Maybe true but power milling is hard on your tools and your machine. I can turn an endmill into a ball mill and still finish the job before I’m even aware of it with high speed machining. My parts come out flatter and my walls are straight within tenths. Aaaaaannd I don’t have to tighten the crap out of my delicate part. Power milling has proven to be faster for sure but when that tool breaks, your holder is damaged and that part is scrapped hsm will have put more money in your pocket from said customer. Unless you have a spare tool in the carriage and the part hasn’t moved and verified it hasn’t. A continuously running hsm program will leave you behind and give you over 3 times the tool life.
I use a different approach. I set up my machines to run as many parts as possible. I bought a brand new, gorgeous VF5XT last year and I fill the 60 x 26 travel with parts. this gives me a 9 hour run time with tool reliability. I can run the machine during the day and then get another run in at night. Maybe I could push it harder but as its lights out machining with nobody at the shop I'm happy with a program that is reliable and doesn't break tools.. ever.

B.e.a.utiful. I just bought a Stellram for my shop, they put me in charge of CNC machining, programming, tooling. I don’t know if that’s a good thing or a bad thing. The old guys love their 20-30ipm. I showed them the Stellram today took it up to 600ipm today.
Nice video and I learnt a thing or two. The only thing I don't understand is why the emphasis is put on feed rate while there are more variables contributing to material removal. Making money with a machine means removing volume as quickly as possible, which would mean cubic inches per minute. The 600ipm pass at a 2.7" stepover was 126 cubic inches per minute The 800ipm pass at a 1.5" stepover was 120 cubic inches per minute BUT with reduced spindle load What I would suggest in search for a metal-hogging recipe is to be at full depth of cut, keep the maximum feed rate and play with the stepover. The reason being, you're paying for big inserts but only use .1 inch of the tip. Any thoughts?
2.7 was definitely a higher HP also... My point was not to bury the tool but just to show everyone the tool could handle a lot... so don't be scared to experiment. My normal feed as seen the the spark plug video is 300-500IPM at Z-.2 which gives me a nice MRR.
𝖘 𝖍 𝖎 𝖗 𝖔 you're right a more complete doc would use the insert more efficiently. Though generally a tool of that size your probably using more for facing style cuts, not so much mass MMR, there's more suitable tools for that
I cut mild steel every day with sandvick r.390 inserts. One thing I've found to save the cutters and inserts is to either be above the screw or below it. Having the cutting pressure concentrated at the thinnest part of the insert leads to inserts breaking. Best strategy is at 1/3 of insert or 2/3. I cut at 40 ipm with 1 inch sandvick and .5 depth of cut using air through tool on my HAAS VF5 XT. Btw, I've been machining since 1980 and the HAAS is the best machine I've ever used. Yes, I've owned Makino, Matsuura etc. HAAS wipes the floor with them.
Are you really gaining ground though? Pushing to 800 is great, but if you're reducing your radial to do it, is it worth it? Especially considering wear on the machine? Great video though, thanks.
Christian Forthofer i worked with a programmer like this. Run crazy speeds, pop the program in, and walk away. Then get pissed we you bitched that you were changing tools every 15 min. $100 in turning inserts by the end of the night with only 0% increase in production because of all the downtime rebuilding tools that failed early.
@@pharaun159 LOL I had a "programmer" come in on a weekend with me, turns out we were programming the same part. His took 2.5hrs and used a 6" long R390 to do most of the roughing, 45 minutes on one tool. You actually had to stop in process, change inserts, and restart from the beginning of the tool. My whole program took 45min and you could actually run it without breaking a tool. He was one of those guys that graduated the machinist course and thought he was a programmer worth $26/hr.
Yeah...I've worked for an owner like this..crank the piss out of it and in 304 or 316 ss, make it through one or two like a hero and walk away for u to inevitably have a crash later...not his fingernails getting chewed....prick
by my crude calculations 2.7 x .1 x 444 ipm = 120cu in per min. 1.5 x .1 x 800 = 120cu in per min. also I would say that the tool can handle it just fine, the machine taps out.
Pretty cool test. 162 in³/min @ 600ipm is more than I expected it would do. Those Stellram cutters are very nice. Do you know how low the rpms dropped on that 600ipm pass? When can we expect a test in steel? :)
at collage I try to push the haas mini mill to it limit, it got a 6000rpm 5.6kw spindle(7.5hp) I then got it running at 7500 mm/m feedrate which is about 300ipm, I then chickhen out as the spindel is reach over 8.9kw(8.9)
I wonder how much of a difference it would have made if you were conventional milling, rather than climb milling, on the original 2.7" step over. When you were on the 600 & 700 passes, it had that big wall that may have messed with chip evacuation. (P.S. I am NOT a machinist. So if that's an absolutely stupid observation and query, forgive me.) Also, I would like to see a video of milling with & without coolant. For example, if you did the *exact* same cuts with coolant and without coolant. Maybe with a parametric graph with the spindle load % & kw, HP, and surface footage. So we could see whether or not the coolant makes an appreciable difference, or any statistically significant difference at all. Maybe even one comparing MQL, mist, HP vs LP flood coolant, WD-40, brushed on cutting style lube like the old school guys use on the manual machines, etc.
For me usually is the workholding that limits the speeds. I can dial in the numbers even larger MRR than that in video but either there's too little material to hold on or poor selection of vises at the moment. Eitherway it costs money better known as opportunity cost. Proper tools always pays off in time and only thing that you can't replace is time so that will always be the most expensive thing in any shop.
It's amazing to see the limits of a machine , but in real life application , this is too scary. Over 400 it really gets out of hand , if something breaks , even "only" 200 brings your hearth rate up :D . Now i wanna see some super high feed turning even if it's just aluminium . (parameters like .1 radial depth , feed .05"/rev , and cutting speed about 6000SFM)
Kiss peter that is the reason the shop I work at loses money, one guy runs and saves aggressive money making programs the next guy "ooo that's too much" and drops feeds and speeds by 50% and burns up tooling
I loved this! As an apprentice machinist this guy can show me da way... haha awesome keep up the CNC videos! coming from washington state! The future must hold more machinists!! lets go!
You must not have watched the end. I simply was showing the the tool can outlast the machine so don’t be scared and then backed it off and said 400 was the sweet spot We run at 400 all the time and never have issues at all...
You da man! That is some scary stuff you just did and pulled it off nicely. Since I work with mostly plastic, aluminum, and stainless steel to me this is very impressive. I hope one day I can make it to just half way to what you know about cutting stuff. Keep up the great work as you are an inspiration to a lot of us just starting in on machining.
We just got the same ngc control in (2018 haas vf5xt). I noticed your chip load you see on the screen is reading correctly as a 4 flute cutter. So far I just programmed tool length and dia of tool . Looks like there is more for me to add (# of flutes)
Nothing against Haas, but you get what you pay for. This is a 40 taper machine and that little spindle just doesn't have gobs of torque like a geared 50 taper with 35+ HP. Bigger machine would also have sturdy box ways and a design that is simply more geared towards beating the shit out of it.
I agree for the most part, Haas machines are cheap but they're very economical. my old shop had a high end Mori, it was a kick ass machine but had a lot of problems and had to be fixed often. My new shop has a vision wide which is a cheap Korean machine, it is really powerful; 55hp and a crap ton of torque but its maxed out at 7000rpm.
A CAT40 taper, linear guide machine is NOT made for old school/box-way hogging. "High speed machining" works because linear guides wear less overtime than boxways and typically the feed rate/rapids are higher on the machine due to the smaller amount of friction. My box way fadal is maxed out at 200ipm. Over that and not only can the processor not keep up, it drains the way oil with a quickness. It's like complaining about not getting your corvette to trailer 10,000lbs loads.
A good test for the machine. If you're up to doing this again, drop the spindle speed to 9k-10k, since it will increase the available torque by about 60% (specifically at 9krpm). The chipload will shoot through the friggen roof at 800 IPM @ 9krpm, but hey that's what the test is for :)
I actually just did this today on my 1996 or 7 VF-6. I was running a similar style high feed face mill on some large 7000 series parts. 7500rpm (max for the machine it's old) at 150ipm 2"step over on a 3 inch shell @ .05doc. Spindle load floated around 100% I was getting fluffy hard to clean out chips. The auger didn't like them...haas... I dropped the rpm down to 5000rpm and everthing else the same. Load went down to 60% so I said ok, more feed? I went up to 240ipm, .05 doc, 5500rpm at 85-90% load. So my mrr went up 62% if i figure right, I got better chips, and didn't kill the machine. So I dropped all my other tools from 7500 that I was using down around 5000-5500 and almost doubled all my feed rates for the milling operations and now the parts are coming out roughly 75% faster. It makes sense thinking about it too. So for hogging I wont be maxing out my spindle, machine just falls flat on its face.
I have been machining like this from day 1 in building my shop and that’s why I have been successful... because I solve my customers problems. You should check my last Vlog on last Friday when I tell the story of starting my shop and sleeping their so I could run machines 24/7. What I have is because I risked it all and put the work in.
So how was the cut on the 500, 600, 700, fpm no coolant runs? As a non-machinist, I'm curious to see how much snipe or chatter there was on the (Y?) axis end of the material. I assume the Z was rough as well. (X?) went through on all but the last pass, so there was nothing to see there. (Not sure if the X was the plate motion, or if the Y was, but I'm assuming X based on the load factor on the screen)
Titan, while finding the sweet spot on any machine is the key to productivity I have this feeling that you wont be happy and you want to make a machine that can actually do 1000 ipm no matter what material you put in its vise !!
Nice nob there , in my experience the sweet spot is a resonating sound that feels like music to the ears. When you hear it you automatically get to know that neither the spindle nor the tool is bearing any abuse. I work in millimetres and using 45 kw spindles , 22000 RPM a feedrate of 7000 - 8000 mm/min , and depth of cut 4-5 mm it feels like and orchestra . With smaller tools 3mm depth of cut is better and safer. Whats your spindle power and torque ?
The volume of material removed per minute is V = Feed x Width of Cut x Depth of Cut. You were actually removing more material per minute at 500 ipm and 2.7" woc than at 800 ipm and 1.5" woc.
Cool vid. but need to know rated power of spindle and chipload per flute as well as chipload per revolution! how many revolutions per min? gotta know stuff but cool vid either way!
20.3 metres a minute is certainly travelling. What RPM were you running? What grade aluminium were you using? Material has a big bearing. Insert geometry also has an influence. All machining is a lot of trade offs between speed, tool use, wear and number of operations in a job. The rapid traverse rates and speed of tool change also can have a bearing in time taken. Would be interested in seeing this performed on steel tho.
I was under the impression that you did not want to enter the cut right at half the cutter diameter, because it is the weakest part of the cut for the insert. For example enter the cut at 1.6" or 1.4" I could be wrong
The us government actually provides a free feeds and speeds chart for all kinds of materials. They do this kind of thing in my hometown. We were told about it by a local machine shop school
OOOH WHAT A WORLD.....It was when tape readers and auto-chuckers ruled the world..!!..I toured the Hardinge plant in Elmira in 83' when my company bought their first Super Slant...Kennametal gave the Spectra Physics fab shop some of their first production tooling to try out on the floor..It was good back then, but now OMG..
Sir , can you please suggest me the best but economical 100mm Dia milling cutter with insert specifications for Aluminium alloy having 10% of silicon...I'm waiting for your reply, thank you Currently I'm using SDHT04
A couple questions, what grade was the aluminum, and did you step up the spindle speed when every increase of feed rate, or did you run the spindle speed the same rpm for every test?
As a MR1(SW)Retired Navy vet w/16 yrs sea duty .. I KNOW when I see power and Damn Good Machinest ... Wish you could Teach Me.. Where where you in '95?
Who cares about IPM, it's all about MMR and you had to step off your radial to hit 800. Your RPM are above the optimal range for best power output on that machine. Lower your spindle speed, get a facemill with more inserts to maintain chipload and get your material removal rates up. MMR is what counts. This video is flash and smoke, all show. If you're saddled with a Haas, at least understand its strengths and weaknesses and play to them. Do you even know what your target chip load is? TH-cam, why do you keep putting this dude in my recommended videos?
The correct approach (IMHO) is to review the torque curve of the mill and run at the RPM that produces Peak torque. then optimize depth of cut and feed rate around that for best MMR. At a certain point the tool stalls or breaks but usually that's to do with clearance of chips from the cut. To improve clearance of chips increase spindle speed - continue to optimize. I was able to triple my MMR over just running the spindle "flat out" and not thinking thru this..
I was ready for the climax at 800 IPM, no coolant, in round one. KO. It was the great prophecy, foretold and expected by all in the title. In a stunning subversion, the solution was to REDUCE THE RADIAL. The next time my spindle load is at 200% and I'm breathing smoke, and I'll remember this little trick.
Hey can someone direct me to a place where I can buy aluminum like that? I’m not a machinist and I don’t have access to tooling equipment (sadly), but I DO need aluminum for metal casting, and seeing that much aluminum being shredded to bits is slightly infuriating tbh
have you tried googling "metal distributors" ? or if you're looking for a low volume of metal and want to make it simple check out mcmaster carr ( mcmaster.com )
Interesting to see this demo on alloy. I would like to see the result if you had tried to do fast speed (ipm) before you had reduced the height with previous cuts. More leverage on part, that would be interesting! Cheers from John, Australia.
I’m a precision engineer in Britain working with hurco CNC milling and Centre Lathes and we run our machines about equivalently what you run those but in millimetres
but I could make the machine work faster by increasing the depth of cut so what do I do make it machine slower with a deeper cut or make the machine work faster? or some combination of the 2?
Awesome video, You're the man. Is Kennametal your brand of choice for indexable cutters? I'm sure you've tried a variety of brands and know your stuff so I'm just curious. I'm in the process of modernizing my machine shop and I am currently focusing on tooling. Keep it up!

Put a larger diameter cutter in an go at less than 50% width of cut, that way the cutter is always climb milling and reducing the force.
Makes no sense if you want to go fast... larger diameter = slower
The coolant made the most difference I'm sure.
Nice video and I learnt a thing or two.
The only thing I don't understand is why the emphasis is put on feed rate while there are more variables contributing to material removal.
Making money with a machine means removing volume as quickly as possible, which would mean cubic inches per minute.

The 800ipm pass at a 1.5" stepover was 120 cubic inches per minute BUT with reduced spindle load
What I would suggest in search for a metal-hogging recipe is to be at full depth of cut, keep the maximum feed rate and play with the stepover. The reason being, you're paying for big inserts but only use .1 inch of the tip.
Any thoughts?
2.7 was definitely a higher HP also... My point was not to bury the tool but just to show everyone the tool could handle a lot... so don't be scared to experiment. My normal feed as seen the the spark plug video is 300-500IPM at Z-.2 which gives me a nice MRR.
𝖘 𝖍 𝖎 𝖗 𝖔 you're right a more complete doc would use the insert more efficiently. Though generally a tool of that size your probably using more for facing style cuts, not so much mass MMR, there's more suitable tools for that
I cut mild steel every day with sandvick r.390 inserts. One thing I've found to save the cutters and inserts is to either be above the screw or below it. Having the cutting pressure concentrated at the thinnest part of the insert leads to inserts breaking. Best strategy is at 1/3 of insert or 2/3. I cut at 40 ipm with 1 inch sandvick and .5 depth of cut using air through tool on my HAAS VF5 XT. Btw, I've been machining since 1980 and the HAAS is the best machine I've ever used. Yes, I've owned Makino, Matsuura etc. HAAS wipes the floor with them.
You should try some DMG, Mori Seiki or Hermle Machines. Those wipe the floor with anything else you know.
"HAAS is the best machine I've ever used" haha
Nice
More positive inserts play a massive difference in spindle load also. Can often increase cutting date this way and also reduce load.
Are you really gaining ground though? Pushing to 800 is great, but if you're reducing your radial to do it, is it worth it? Especially considering wear on the machine?
Great video though, thanks.
They real machinists calculate their Material Removal Rate vs their chip load.
Cutting your MRR by 25% to get to 800ipm, thats not epic manufacturing, thats an epic fail.
Christian Forthofer i worked with a programmer like this. Run crazy speeds, pop the program in, and walk away. Then get pissed we you bitched that you were changing tools every 15 min. $100 in turning inserts by the end of the night with only 0% increase in production because of all the downtime rebuilding tools that failed early.
LOL technically a little MORE silly video showing how to do it the wrong way and HURT production AND Tool life at the same time
@@pharaun159 LOL I had a "programmer" come in on a weekend with me, turns out we were programming the same part. His took 2.5hrs and used a 6" long R390 to do most of the roughing, 45 minutes on one tool. You actually had to stop in process, change inserts, and restart from the beginning of the tool.
My whole program took 45min and you could actually run it without breaking a tool.
He was one of those guys that graduated the machinist course and thought he was a programmer worth $26/hr.
Yeah...I've worked for an owner like this..crank the piss out of it and in 304 or 316 ss, make it through one or two like a hero and walk away for u to inevitably have a crash later...not his fingernails getting chewed....prick
by my crude calculations 2.7 x .1 x 444 ipm = 120cu in per min. 1.5 x .1 x 800 = 120cu in per min. also I would say that the tool can handle it just fine, the machine taps out.
Pretty cool test. 162 in³/min @ 600ipm is more than I expected it would do. Those Stellram cutters are very nice. Do you know how low the rpms dropped on that 600ipm pass?
When can we expect a test in steel? :)
I am going to start testing a lot of tools in different materials and machines. This will be a regular feature : Tools of Domination.
Yes we want to see you break shit!!
Man that was smoking, a good job good results and good to see Stuart predicted correctly the outcome at them settings :)
at collage I try to push the haas mini mill to it limit, it got a 6000rpm 5.6kw spindle(7.5hp) I then got it running at 7500 mm/m feedrate which is about 300ipm, I then chickhen out as the spindel is reach over 8.9kw(8.9)
ive got to be the biggest viewer i come back and watch this often .
Man,turn the quill on.
What a crack up.
Great demo thanks.😁
That was awesome! Would love to see a comparison of the finishes for each cut too.
I wonder how much of a difference it would have made if you were conventional milling, rather than climb milling, on the original 2.7" step over. When you were on the 600 & 700 passes, it had that big wall that may have messed with chip evacuation. (P.S. I am NOT a machinist. So if that's an absolutely stupid observation and query, forgive me.)
Also, I would like to see a video of milling with & without coolant. For example, if you did the *exact* same cuts with coolant and without coolant. Maybe with a parametric graph with the spindle load % & kw, HP, and surface footage. So we could see whether or not the coolant makes an appreciable difference, or any statistically significant difference at all.
Maybe even one comparing MQL, mist, HP vs LP flood coolant, WD-40, brushed on cutting style lube like the old school guys use on the manual machines, etc.
For me usually is the workholding that limits the speeds. I can dial in the numbers even larger MRR than that in video but either there's too little material to hold on or poor selection of vises at the moment. Eitherway it costs money better known as opportunity cost. Proper tools always pays off in time and only thing that you can't replace is time so that will always be the most expensive thing in any shop.
It's amazing to see the limits of a machine , but in real life application , this is too scary. Over 400 it really gets out of hand , if something breaks , even "only" 200 brings your hearth rate up :D .
Now i wanna see some super high feed turning even if it's just aluminium . (parameters like .1 radial depth , feed .05"/rev , and cutting speed about 6000SFM)
You must not have watched it til the end...
i did , but that is just too much for the machine . so what about pushing turning to the limit ?
Kiss peter that is the reason the shop I work at loses money, one guy runs and saves aggressive money making programs the next guy "ooo that's too much" and drops feeds and speeds by 50% and burns up tooling
Holy shit that was insane I've never seen anyone push a machine that hard before!!
I work in maintenance so this made me cringe lol
I loved this! As an apprentice machinist this guy can show me da way... haha awesome keep up the CNC videos! coming from washington state! The future must hold more machinists!! lets go!
The video show you fast the thing cut but doesn't show you tool life comparision, the over all money ratio to profit at the end.
You must not have watched the end. I simply was showing the the tool can outlast the machine so don’t be scared and then backed it off and said 400 was the sweet spot
We run at 400 all the time and never have issues at all...
You didn't show the surface finish after each pass? Also, how well did the inserts hold up under the extreme load?
What about the finished surface at this amazing parameter? Have you documented it?
You da man! That is some scary stuff you just did and pulled it off nicely. Since I work with mostly plastic, aluminum, and stainless steel to me this is very impressive. I hope one day I can make it to just half way to what you know about cutting stuff. Keep up the great work as you are an inspiration to a lot of us just starting in on machining.
We just got the same ngc control in (2018 haas vf5xt). I noticed your chip load you see on the screen is reading correctly as a 4 flute cutter. So far I just programmed tool length and dia of tool . Looks like there is more for me to add (# of flutes)
Have to love the variables, from a parametric programmer👽
Awesome video. Just wanted to know if you changed the inserts for every pass?
very nice tutorials,
i watch almost all of them
Nothing against Haas, but you get what you pay for. This is a 40 taper machine and that little spindle just doesn't have gobs of torque like a geared 50 taper with 35+ HP. Bigger machine would also have sturdy box ways and a design that is simply more geared towards beating the shit out of it.
I agree for the most part, Haas machines are cheap but they're very economical. my old shop had a high end Mori, it was a kick ass machine but had a lot of problems and had to be fixed often. My new shop has a vision wide which is a cheap Korean machine, it is really powerful; 55hp and a crap ton of torque but its maxed out at 7000rpm.
A CAT40 taper, linear guide machine is NOT made for old school/box-way hogging. "High speed machining" works because linear guides wear less overtime than boxways and typically the feed rate/rapids are higher on the machine due to the smaller amount of friction. My box way fadal is maxed out at 200ipm. Over that and not only can the processor not keep up, it drains the way oil with a quickness.
It's like complaining about not getting your corvette to trailer 10,000lbs loads.
Eggs you're wrong vf6 model is a 50 taper machine.
Vlad The Impaler: The machine in this video is a #40-taper and according to Haas homepage the VF-6 is also a #40-taper.
you can get Haas VF-5 or VF-6 at either 40 or 50 taper. It depends upon the individual machine.
A good test for the machine. If you're up to doing this again, drop the spindle speed to 9k-10k, since it will increase the available torque by about 60% (specifically at 9krpm). The chipload will shoot through the friggen roof at 800 IPM @ 9krpm, but hey that's what the test is for :)
I actually just did this today on my 1996 or 7 VF-6. I was running a similar style high feed face mill on some large 7000 series parts. 7500rpm (max for the machine it's old) at 150ipm 2"step over on a 3 inch shell @ .05doc. Spindle load floated around 100% I was getting fluffy hard to clean out chips. The auger didn't like them...haas... I dropped the rpm down to 5000rpm and everthing else the same. Load went down to 60% so I said ok, more feed? I went up to 240ipm, .05 doc, 5500rpm at 85-90% load. So my mrr went up 62% if i figure right, I got better chips, and didn't kill the machine. So I dropped all my other tools from 7500 that I was using down around 5000-5500 and almost doubled all my feed rates for the milling operations and now the parts are coming out roughly 75% faster. It makes sense thinking about it too. So for hogging I wont be maxing out my spindle, machine just falls flat on its face.
When Haas and Kennemetal give you your stuff, I would rag it out too
I have been machining like this from day 1 in building my shop and that’s why I have been successful... because I solve my customers problems.
You should check my last Vlog on last Friday when I tell the story of starting my shop and sleeping their so I could run machines 24/7.
What I have is because I risked it all and put the work in.
So how was the cut on the 500, 600, 700, fpm no coolant runs? As a non-machinist, I'm curious to see how much snipe or chatter there was on the (Y?) axis end of the material. I assume the Z was rough as well. (X?) went through on all but the last pass, so there was nothing to see there. (Not sure if the X was the plate motion, or if the Y was, but I'm assuming X based on the load factor on the screen)
Your an epic man and amazing .... inspiring and brave .... nice demo and its a great tuturial who understood what were you doing ....
Thank you for all your effort to teach. Please let me understand better about the "sweet spot point" This point is between 80'to 100% of spindel load?
wow, im surprised the surface finish was still very good at that high feed rate, great vid guys.
Who would have thought that cooling and lubricating while machining would lower the effort needed....
Titan, while finding the sweet spot on any machine is the key to productivity I have this feeling that you wont be happy and you want to make a machine that can actually do 1000 ipm no matter what material you put in its vise !!
The Fadal I was running yesterday cant even rapid at 800 IPM more like 700 ipm rapid at most. This is crazy stuff.
Nice nob there , in my experience the sweet spot is a resonating sound that feels like music to the ears. When you hear it you automatically get to know that neither the spindle nor the tool is bearing any abuse. I work in millimetres and using 45 kw spindles , 22000 RPM a feedrate of 7000 - 8000 mm/min , and depth of cut 4-5 mm it feels like and orchestra . With smaller tools 3mm depth of cut is better and safer. Whats your spindle power and torque ?
Adding the coolant,I bet, made a difference. I wonder what would've happened if you increased the spindle speed?
Very nice video, thanks for uploading
I want Type3 Software, do u have it?
The volume of material removed per minute is V = Feed x Width of Cut x Depth of Cut. You were actually removing more material per minute at 500 ipm and 2.7" woc than at 800 ipm and 1.5" woc.
Cool vid. but need to know rated power of spindle and chipload per flute as well as chipload per revolution! how many revolutions per min? gotta know stuff but cool vid either way!
Hello.What is Your Best Insert for Monell Welding Interroupted Cut For a Lathe ?
THANKS.
Most can't possibly understand how this feels to see this after miles of machining
20.3 metres a minute is certainly travelling. What RPM were you running? What grade aluminium were you using? Material has a big bearing.
Insert geometry also has an influence.
All machining is a lot of trade offs between speed, tool use, wear and number of operations in a job.
The rapid traverse rates and speed of tool change also can have a bearing in time taken.
Would be interested in seeing this performed on steel tho.
I just bought one of these Stellram tools for my shop. You should have seen the look on my bosses face when he saw me bulldoze the material away
Probably shit a one ton brick in his pants, didn't he?
Is this aluminum or aluminium? Can't tell.
I was under the impression that you did not want to enter the cut right at half the cutter diameter, because it is the weakest part of the cut for the insert. For example enter the cut at 1.6" or 1.4" I could be wrong
Yeah coolant will stop aluminium from weding onto the cutter. I cringed until you finally turned it on. Thanks for the video.
I am learning a lot from Titans, get the speed and accuracy dial in and we are in the $$$.
The us government actually provides a free feeds and speeds chart for all kinds of materials. They do this kind of thing in my hometown. We were told about it by a local machine shop school
Doesn't really apply with 10k+ rpm CNC milling machines that are designed for high speed mass production.
400 ipm looked like the sweet spot
OOOH WHAT A WORLD.....It was when tape readers and auto-chuckers ruled the world..!!..I toured the Hardinge plant in Elmira in 83' when my company bought their first Super Slant...Kennametal gave the Spectra Physics fab shop some of their first production tooling to try out on the floor..It was good back then, but now OMG..
Mgyver D but a HLVH is still one of the best machines ever made, aside from the 10EE.
What does "stepping in at -2.700 radial" mean? What does the "radial" parameter mean?
Just that the tool is 3.0” and 2.7 is engaged in material cutting.
This kind of experimentation is fun when you have the time to play like that. I"m curious, when you hit 600 IPM, what was the chip load per tooth?
Assuming a 12k spindle and 5 inserts the chip load was . 01 per insert per rev
Sir , can you please suggest me the best but economical 100mm Dia milling cutter with insert specifications for Aluminium alloy having 10% of silicon...I'm waiting for your reply, thank you
Currently I'm using SDHT04
You're positive the sudden large load and smoke isn't from the tool rubbing behind/after each insert?
And Hardness materials are different 😉 ..moreover you're amazing ..whereas you're risking a lot in this trial ... You're the best 👍
A couple questions, what grade was the aluminum, and did you step up the spindle speed when every increase of feed rate, or did you run the spindle speed the same rpm for every test?
6061 is what he said at the end.
As a MR1(SW)Retired Navy vet w/16 yrs sea duty .. I KNOW when I see power and Damn Good Machinest ... Wish you could Teach Me.. Where where you in '95?
Who cares about IPM, it's all about MMR and you had to step off your radial to hit 800. Your RPM are above the optimal range for best power output on that machine. Lower your spindle speed, get a facemill with more inserts to maintain chipload and get your material removal rates up. MMR is what counts. This video is flash and smoke, all show. If you're saddled with a Haas, at least understand its strengths and weaknesses and play to them. Do you even know what your target chip load is?
TH-cam, why do you keep putting this dude in my recommended videos?
The correct approach (IMHO) is to review the torque curve of the mill and run at the RPM that produces Peak torque. then optimize depth of cut and feed rate around that for best MMR. At a certain point the tool stalls or breaks but usually that's to do with clearance of chips from the cut. To improve clearance of chips increase spindle speed - continue to optimize. I was able to triple my MMR over just running the spindle "flat out" and not thinking thru this..
This is a hell of an advertisement.
How much effect do you have in your spindle? Sometimes we just hit machine limit before tool limit.
I was ready for the climax at 800 IPM, no coolant, in round one. KO. It was the great prophecy, foretold and expected by all in the title. In a stunning subversion, the solution was to REDUCE THE RADIAL. The next time my spindle load is at 200% and I'm breathing smoke, and I'll remember this little trick.
That is the best thing I've seen in a long time it probably would have went through if it had new inserts
This dude listened to all episodes of the Jocko Podcast. "We're at max? Good. Back off, reload, recalibrate, REENGAGE!"
I find the finish so good on the deep cuts
Hey can someone direct me to a place where I can buy aluminum like that? I’m not a machinist and I don’t have access to tooling equipment (sadly), but I DO need aluminum for metal casting, and seeing that much aluminum being shredded to bits is slightly infuriating tbh
have you tried googling "metal distributors" ? or if you're looking for a low volume of metal and want to make it simple check out mcmaster carr ( mcmaster.com )
Interesting to see this demo on alloy. I would like to see the result if you had tried to do fast speed (ipm) before you had reduced the height with previous cuts. More leverage on part, that would be interesting! Cheers from John, Australia.
try that in D-2 and I might be impressed, you can do the same with high speed tooling in aluminum
:-)
Do your machines come with body armor for the operators ?
Can yu please tell me whats the best insert i can get to machine cast iron
RA VALUE SHOULD BE LESS THEN 3.2
What is the best software or application for calculating speeds and feeds for cnc machining?
NOVO from Kennemetal is Great
@@TITANSofCNC Thanks Titan.........Amazing Response Time. All the best to you in 2019!
I’m a precision engineer in Britain working with hurco CNC milling and Centre Lathes and we run our machines about equivalently what you run those but in millimetres
I could almost smell the metal at 600, haha... I wish I was there to see it live
but I could make the machine work faster by increasing the depth of cut so what do I do make it machine slower with a deeper cut or make the machine work faster? or some combination of the 2?
Awesome video, You're the man. Is Kennametal your brand of choice for indexable cutters? I'm sure you've tried a variety of brands and know your stuff so I'm just curious. I'm in the process of modernizing my machine shop and I am currently focusing on tooling. Keep it up!
The inserts were smoked at 500. Coolant is the make it or break it at these feeds and speeds.
Not really... inserts were fine. Machine drew the limits not the inserts
i assume you used the same side of the inserts for all the tests? there was probably build up on the inserts once you got to the high IPM
I would've liked to see some chip analysis on this, just to see what kinda chips are breaking across the board at the different feeds.
I want one of your titans of cncs T-shirt’s! I enjoy watching the videos you guys post!
