Thanks for sharing another CNC video. Love your channel. Keep those videos coming. I am a hobbyist machinist and also have the Renishaw Wireless Probe and Tool Setter on my HAAS TM1P. I know the Tool Setter is coolant proof but I found an old piece of tupperware with the right depth and diameter and turned it upside down to cover the Tool Setter while using the machine in normal use. The only time I take it off is when I am setting tool heights. This keeps the coolant and chips off of the tool setter. I also made an manual and automatic air blast system that I attached to my PCOOL nozzle. I mostly use it in the manual mode with a foot pedal. When I want to get rid of any excess chips I just give the old foot pedal a press and presto the chips are blown away from the part. In the automatic mode with the help of one of my internet buddies I was able to set the length of time the blast will occur and how often the air blast will occur. The air blast system allows me to keep the door shut and keep the coolant inside the machine.😊
Seeing the steel block and some of the difficulties you experienced while machining took me back to the mid to late 1980s when i was working on the JP233 project. Part of the submunition was 30 runway crating bomblets. Part of that system was made from a 2.5% Nickel Chromium Molybdenum steel. It 2as by far the most awkward steel I have ever worked with. Hard spots, drills and taps breaking, inserts blunting/chipping, tools pushing off, surface finish problems. We completed the contract and the whole stock of JP233s was used by the R.A.F. and the Royal Saudi Air Force during Operation Desert Storm. Good post explaining the difficulties and remedies, thanks for posting.
I love your manual machining and I'm loving your move into CNC. It's all starting to come together and if it means you can turn out better quality parts, faster for your customers, you'll get more customers. Lots of naysayers here, but you have to make a living, you do what you need to do.
You answered my question. When i was machining 410 stainless, we were running full depth with a 3/4 in rougher/finisher, 5-7% stepover, 4500 rpm, 60-80ipm, constant surface feet program. (I forget the trade name) 1 1/8 depth of cut, but a pretty light stepover. It sounded like a wood shop, it was singing. Plus, many times we ran them dry!
Ten percent of tool diameter is a good starting point for radial engagement. It will really depend on what your machine/setup/tooling will allow. As you learn and grow more confident and comfoertable you will realize cnc machines are capable of things that you could never imagine. Every once in a while i look back at old programs i made where i thought i was really pushing the limits and find out just how slow and gentle i was going. Just keep working at it and you will find the sweet spot for you.
You may still be learning the Computer Controlled part of Machining - but you instantly understood about the burned inserts (and more importantly why they burned up). Your experience and knowledge of machining principles shows. Another fine video, Adam.
Just recently having seen a video on issues with "confidence bias" or the "Dunning -Kruger-Effect". Adams attitude toward his capabilities helps him with that and is something we all should keep in our minds. Despite being a great machinist already, especially with this new to him technology, he freely and openly admits still to be learning and not knowing everything. Something I always find strange in people not admitting, who in the world can know everything, even on a particular subject. Knowing and admitting that, he still has the confidence to try, but tries not to get over confident and thus he keeps learning and improving. So for a lot of those people out there, with all those variations, differences and daily new stuf, it is no shame to admit not knowing everything. It is a strength on which you can build up your skills. Never stop learning!
I am fascinated watching you with this new age machinery. I'm 73 and this is all new world technology. Top marks mate for teaching yourself on these space age machines. New Zealand.
Good catch remembering previous tool paths and results to rectify unsatisfactory results and recovering those errors. Enjoying your educational endeavors, especially using these state of the art CNC machines. That Titan endmill should take .0050 doc, but finish will suffer.
Nice having the pieces from your buddy to play with and continue your learning process. Hate to have to waste good stock. You are coming along nicely. Thanks for sharing.
Thanks for taking us along. That is an impressive machine I did have to laugh though, because everything about that set up is so impressive. But it still needed a $0.99 chip brush. I only hope that you laugh about it to. Another entertaining video!
Adam, you mentioned the rapid override in relation to the feed of the cutter. The rapid override shouldn't change the cutters feed rate. Only the rapid feed rate. In fact does the rapid override on your machine go to zero? If so this can be used to advantage while running the program. By setting it to zero while the machine is feeding it will stop before any rapid move. Until you turn the knob off of zero rapid feed. On running in a tool for the first time. There should be a distance to go display on your control. This shows the distance the tool has to go to reach the end of the move it is currently on. So running a tool the first time press feed hold as the tool rapids down to the work. With the machine now stopped look at your distance to go display in the Z axis. If the distance to go in the Z looks wrong for some reason. Like there is only an inch to go but the display shows more than that. Stop the machine and correct the problem. It is better to stop and check then to regret it later. This can also be used in moves in the X and Y axis while milling. For instance when your chamfering cutter is approaching the part. You could also press feed hold just before it reaches the edge. Then look at the distance to go in X and Y. If there are some big numbers it's going to cut the chamfer to large . I generally like to start a chamfering cutter off the corner of a part, like this instead of arcing in. That way if something is wrong it is easier to catch/see it before cutting to much of a chamfer. Otherwise it looks like you are getting this CNC stuff pretty well. At first it's a little intimidating. But it will all become second nature like running a manual machine is to you.
Hi Adam, Glad to see you are getting more confident with your new machine. Re the surface finish from your face mill. If your feed per tooth exceeds the width of the wiper flat on the insert your finish will certainly look like that. Also are they precision ground inserts or as sintered as the tolerance difference between the two may mean one insert is sitting a little higher which will also give that effect. I worked 28 years for Seco Tools of Sweden and really enjoyed the milling side of the range. There are so many things that can effect surface finish. Cheers Ian New Zealand
18:30 My turning instructor was right. "If your tool is almost sharp, it will almost cut." I've found those to be words to live by. He also said "If you wonder if it's dull, it probably has been for some time so don't be surprised at the improvement when you sharpen it." He was speaking of HSS but it's true of any cutting edge on any material.
The night and day difference between the passes with the old and new cutters is crazy. Completely different sound and everything. A really good example of why it's good to make sure your tools are in good shape. Probably could have made the part to the right dimensions with the bad cutters, but it wouldn't look nearly as good and would be a lot harder to get into spec.
Learning on your own, and my own, creates an unorthodox way of doing things. You invent ways to accomplish your intended goal. Help is fine and needed as well, but in the end you have a solid chance of learning something that no could teach you. You invent processes that others aren't aware of. Then you can truly teach the pro's a new trick and they can teach you their old tricks.
He learnt manual machining the orthodox way, from the ground up, learning from his dad, grandad and employee Sonny before extending his skills at Motion. He's learning CNC the hard way, by himself; which in turn can breed bad habits and inefficient methods. Much easier and thorough to learn it as an employee in the CNC industry, and so learn the techniques and methods presently used. Then if you feel you can improve on them, then that's your opportunity to shine.
Nice video Adam your coming right along with your new CNC machines looking good. I am a old salty fart that is old school but, I must say those new Cutting Edge technology sure does a nice job but that technology is as good as the people running. Once again great job Adam can't wait for the next video.
This sorta reminds me of when I started using 3D printers. You can take on a lot of advice from other people but sometimes you've just got to dive in and try things on your own setup. Nice work Adam. Thanks!
As others probably have said. I'm sure it was just the bad corners on the inserts. Rapid should only change how fast the tool is moving when it's not feeding, so that shouldn't have had anything to do with it. Good practice piece though. Those jaws looked like they held it in place really well. I wish we had some of those.
Wish you would show the Gcode while it's running that would be interesting. I don't know if you watch it or not but as you're gaining experience with Cnc machines it's very helpful to learn to follow along and especially to read the code before you push that awful GREEN button and understand what is about to happen. I do this everytime I run a program. It calms my nerves alot to know exactly what is about to happen but I still keep my finger on the red button and turn the rapids down low on the first part until I'm confident all my offsets are working as planned. Great content, the CNC stuff is very interesting and I do it all day everyday at work...LOL
What's up with all the people hating the new cnc setups? He's trying out his new gizmos and sharing with us, no need to get on his ass about ditching manual machining
In the machining world there're alot of guys who will flat out refuse to try something new. There're still use for manual machine but CNC is the future and soon 3D printing will be. I already told people that soon there will be no need to CNC Programmer as AI will take over.
8-10% radial engagement is pretty good for up to 1.5x of the cutting diameter in axial depth. That said, 3/4" end mill for 1" axial depth a good radial DOC is .070. For feed rate .004" chip load per tooth is pretty good, that would put you at just under 20 IPM
I like to use a roughing end mill to make smaller chips. Then use the finish end mill for the final pass. The coolant does a good job of flushing the smaller chips away.
Adam, get yourself a 1 1/2 indexed end mill and step down say 50tho depth of cut back and forth until it cuts the sides away. Then use the same tool to face cut. Iscar makes some that will cut at amazing speeds. I programmed for years and ran part time. This is by far the fastest method. We tested alot in the automotive tooling world.
Adam, please educate me on the milling direction that you prefer or is necessary. My brain tells me to operate the feed against the rotation of the cutter, yet I see you feeding "towards the grain" so to speak. Have I been milling wrong all this time? Thank you for your outstanding education during the videos. Love it!
A full answer to that question is both complicated and beyond my expertise, but the short answer I can give you. The answer is different for manual machines versus CNC machines. What you see in this video is "climb cutting," which means cutting so that the tool tends to pull the work in the same direction as the travel. On manual machines, you are usually dealing with significant backlash, which makes climb cutting risky--potentially even dangerous. The rule of thumb is "never" climb-cut on a conventional machine, although sometimes you will see somebody take a very light climb cut to get a better surface finish. Always cut so that the tool pushes against the motion of the axis--called "conventional" cutting. CNC machines, on the other hand, are built with virtually zero backlash--typically by using ballscrews instead of conventional Acme screws for the axis drives. Therefore climb cutting is generally safe on this machine, and typically preferred because of the aforementioned better surface finish--although a quick Google search will turn up many people arguing that conventional cutting is to be preferred in this or that particular situation.
I doubt I will ever do CNC, but I do find it interesting to watch. This made me think of the vice build for the WIYB. Might consider making a trial of that one by CNC, after you get some more confidence with your software.
You should make a little box to put over your tool setter, a stringy chip from a drill might tear it apart. We have on all our milling machines something with a cap and a hinge to flip it open when setting tools.
Hey Adam, one of the first series I watched of yours was the making of the body of the tool maker's vise for the Bar Z bash (I think) giveaway, you and a number of others worked on it. I would love to see you duplicate that project using the CNC tools this time around, and it would either be a handy shop tool or an amazing giveaway piece.
8:16 chip problems.. Search Control Your Chips! Chip Splitters and Roughing End Mills - Haas Automation. If you would like a little more detailed info on dealing with those chips. I think you probably already k ow why/what to do to mitigate that problem, but that video is super helpful anyway🙂
Is there a coolant source near the base that could be used for a jet to spray the back of the vise? Maybe with lines similar to the ones for the spindle but with a smaller nozzle for a more pressurized stream to clear away the chips. It didn't look like the coolant gun was blowing the chips away.
I think the only thing you are missing on your machine is high pressure coolant. You were wondering about your 1/4 depth of cut, the rule I was told was you can go up to half the tool diameter when side milling like that. So on a 3/4 diameter tool you should be able to side mill .375 deep
I prefer to cut steel dry in CNC mill. The surface tension of the coolant makes it want to nest up the chips like that, when theyre dry they tend to just go flying. Running faster or making heavier chips helps with chip evacuation as well.
Do you mean feed at 100%? You can have a separate override for feed and rapid. rapids are making the machine move as fast as it possibly can using a g00. In your case moving between events or it can be on the return of something like a peck drill cycle. You can have a rapid set at say 50% and if its independently controlled from the feed override its still going to feed at the rate it was commanded
Hi Abom, Try to put some angle plate near the tool probe, because it is easy to broke it during normal operation, cleaning or in case of tool crash. Setting back the probe can costs up to half of hour. Regards.
Never seen jaw blocks like that for a Kurt vise, did you make them? That would have made my life way easier for 20yrs 😂 working on raw castings and plasma cut profiles...
wish you would use coolant on those big surfacing cuts, that thing was heating up. im willing to wait for the end of run cleaned off version to save you some inserts.
I thought that vise was so cool when you first got it and set it up, now you have another cool tool!! Did that coolant spray gun come with the mill or was it something you added?
push that tool! that baby should take a 15-20% steep at that feed / speed. i run 1/2 tools 1.25" deep @ 25% step 2500rpm @ 32 imp in A2 tool steel. gotta see that that new vise its made of
Setting the rapids (G00) at 50% doesn't affect 'cutting' time (G01). Just the return between cuts. It's good to have the rapids down at the start of a program when you are single blocking but once you know it isn't going to crash into anything consider putting them back to 100% again. Interesting that you didn't use coolant on the shell mill. Is that what Walter recommend for that type of steel?
Adam, what kind of chip load and rpm are you running? Material? Are you using a constant chip load type of programming (high speed roughing or profiling), or is it a constant surface feet type of software? Thanks, like your show.
Today's Cutting Edge Engineering video starts out with a recommendation video from Adam Savage! Apparently a long time subscriber. Says he's obsessed with Kurtis's mastery and recommends Kurtis to his viewers. That should really blow up CCE! Adam promises to stop by and visit Kurtis and sent some customized gifts as well. Can't do better than that. Maybe some sponsors will acknowledge the real force in machinery channels now! Already 55K views in 4 hours.
@andrewterry8092 He says he will move into CNC when he has time to do it right. Apparently, one of his brothers already does CNC, as I recall. He purchased a used machine a while ago but ended up parting it out as it wasn't worthwhile to him to repair. Regardless, when he does start using CNC, I don't expect a steep learning curve. His views are already 10 times this channel, I 'll have to check Social Blade to see how Adam's endorsement affects subs and views. An unsolicited endorsement like this can really be a game changer, as they say.
@longcaster At best, Abom is journeyman level, on a good day, with the sun shining, in a leap year! Kurtis is a master, his shop made tools rival the most expensive store-bought, often surpassing them! He never halfasses anything, unlike Abom. No wonder Adam Savage gave him a shout-out! If he was here in the U.S. and not Australia he would be a breakout star on Discovery for sure! And he is definitely not a wannabe lifestyle influencer like Abom!
Thanks for sharing another CNC video. Love your channel. Keep those videos coming.
I am a hobbyist machinist and also have the Renishaw Wireless Probe and Tool Setter on my HAAS TM1P.

A mid week bonus video!! Def made my day!!!
Building confidence, great work Adam, keep going and you will achieve the goal of small batch run work that big shops don’t like…

Wonderful video.
Looking forward to see actual products come out of this fascinating machine :)
Love the new CNC content!
"sparks flew, emotions ran high..."😂
This sorta reminds me of when I started using 3D printers. You can take on a lot of advice from other people but sometimes you've just got to dive in and try things on your own setup. Nice work Adam. Thanks!
Mid week Abom Video....YES PLEASE!, something to kick back grab the popcorn and enjoy it in surround sound Audio!
Good stuff, Abomb! You could probably push that big mill at a bit faster sfm and ipm. I also like to you a shredder type chip breaker mill
Looks like you could use some higher pressure coolant
As others probably have said. I'm sure it was just the bad corners on the inserts. Rapid should only change how fast the tool is moving when it's not feeding, so that shouldn't have had anything to do with it. Good practice piece though. Those jaws looked like they held it in place really well. I wish we had some of those.
Holy - that surface finish 😮 nice work
Consider using a helical in path for facing so the cutter is always climb milling.
Thank you for amazing video as always!! Personally I’ve never touched the lathe but I will one day have my own!
Happy to be the first watch! Cheers from Austin Texas.
Wish you would show the Gcode while it's running that would be interesting.

He has a conversational machine that shows a mastercam like simulation of the cut.
She's a real chip spitter.

Don't let the critics get to you. It's all about learning and getting to place where that mill becomes a profitable part of the business.
Live and learn. Good stuff.
Great video, thanks
Experience and time will help you sort out all the small details. Well done.
Don’t worry about the chips we’re they lay, unless the end up in the cut(recutting)
You have the coolest toys, I mean "tools", totally tools, for "working", and stuff… 😂
I like to use a roughing end mill to make smaller chips. Then use the finish end mill for the final pass. The coolant does a good job of flushing the smaller chips away.
Hog ugly, save your best tools for finishing. Thanks for sharing.
Nice work Adam. Keep plugging along.
What you should do is program your logo into the machine put your logo onto the part and use it as a display piece
Just wanted to say i came for the comments 😆
Adam, get yourself a 1 1/2 indexed end mill and step down say 50tho depth of cut back and forth until it cuts the sides away. Then use the same tool to face cut. Iscar makes some that will cut at amazing speeds. I programmed for years and ran part time. This is by far the fastest method. We tested alot in the automotive tooling world.
Hey Adam do you think you could show us the programming for a part like that?

Is there a coolant source near the base that could be used for a jet to spray the back of the vise? Maybe with lines similar to the ones for the spindle but with a smaller nozzle for a more pressurized stream to clear away the chips. It didn't look like the coolant gun was blowing the chips away.
Your are starting to sound like a cnc guy. I can tell the confidence is building.
Muy buen trabajo amigo me encanta como se mueve ese CNC 🙏👍
When you turn the rapid to 50 percent it does not affect the feedrate. So i dont think that affected the inserts.
He probably meant feed over ride knob.
6:30 it looks as if your arbor was cooked somewhere? A little bit on the golden brown side
I think the only thing you are missing on your machine is high pressure coolant. You were wondering about your 1/4 depth of cut, the rule I was told was you can go up to half the tool diameter when side milling like that. So on a 3/4 diameter tool you should be able to side mill .375 deep
great video. practice practice
Put a brush in the tool holder and have it sweep every so often. 😊
Don't need a fancy spinny thing...
Does that machine spindle have thru coolant?
I prefer to cut steel dry in CNC mill. The surface tension of the coolant makes it want to nest up the chips like that, when theyre dry they tend to just go flying.
Running faster or making heavier chips helps with chip evacuation as well.
Would be interested how you do the programming and settings in the computer! That is still a mystery to me.
Use something like Mastercam. You don't want to write G code by hand. BTDT. Ugly.
Hello sir hope you’re having a wonderful day
Do you mean feed at 100%? You can have a separate override for feed and rapid. rapids are making the machine move as fast as it possibly can using a g00. In your case moving between events or it can be on the return of something like a peck drill cycle. You can have a rapid set at say 50% and if its independently controlled from the feed override its still going to feed at the rate it was commanded
Hi Abom,
Try to put some angle plate near the tool probe, because it is easy to broke it during normal operation, cleaning or in case of tool crash. Setting back the probe can costs up to half of hour.
Regards.
8:14 raise your rpm and feedrate and possibly lower your woc and cut dry, then the chips will fly away on their own :)
Is there anything in the programming that accounts for cutter wear as the milling progresses? Thanks.
What are you making?
Just chips for now. 😊
And a lot of experience.
Seem like someone with more talent than me should help Abom make a CNC shaper
Never seen jaw blocks like that for a Kurt vise, did you make them? That would have made my life way easier for 20yrs 😂 working on raw castings and plasma cut profiles...
He did a video on those vice jaws a few weeks ago.
You need more coolant pressure for chip evacuation. The tool is making nice chips.
Adam!!! Look into radial chip thinning!! Dapra cutting tools has a good article on the subject. Jack those feed rates UP!
wish you would use coolant on those big surfacing cuts, that thing was heating up. im willing to wait for the end of run cleaned off version to save you some inserts.
I thought that vise was so cool when you first got it and set it up, now you have another cool tool!! Did that coolant spray gun come with the mill or was it something you added?
push that tool! that baby should take a 15-20% steep at that feed / speed. i run 1/2 tools 1.25" deep @ 25% step 2500rpm @ 32 imp in A2 tool steel. gotta see that that new vise its made of
Never seen that kind of vice before.
Yes, that was wicked and immoral behavior as opposed to a mechanical work-holding device...
So nice to do outside radii.
Hi Adam! My favorite type of content! Hi to your wife and it’s nice to have a mid week video! Take care!❤️
Looks dang good
Setting the rapids (G00) at 50% doesn't affect 'cutting' time (G01). Just the return between cuts. It's good to have the rapids down at the start of a program when you are single blocking but once you know it isn't going to crash into anything consider putting them back to 100% again.
Interesting that you didn't use coolant on the shell mill. Is that what Walter recommend for that type of steel?
This is AWESOME 😍
Adam, what kind of chip load and rpm are you running? Material? Are you using a constant chip load type of programming (high speed roughing or profiling), or is it a constant surface feet type of software? Thanks, like your show.
Wow, you really are taking advantage of that heat shrink tooling with passes that match my desktop Taig CNC
Should you machine mill scale or grind it off first?
Cut underneath the scale.
You have a machine with a built-in squirt gun.
Today's Cutting Edge Engineering video starts out with a recommendation video from Adam Savage! Apparently a long time subscriber. Says he's obsessed with Kurtis's mastery and recommends Kurtis to his viewers. That should really blow up CCE! Adam promises to stop by and visit Kurtis and sent some customized gifts as well. Can't do better than that. Maybe some sponsors will acknowledge the real force in machinery channels now! Already 55K views in 4 hours.
I saw that, a well deserved accolade for Kurtis and Karen. And not a CNC in the shop! How does Kurtis do it???
@andrewterry8092 He says he will move into CNC when he has time to do it right. Apparently, one of his brothers already does CNC, as I recall. He purchased a used machine a while ago but ended up parting it out as it wasn't worthwhile to him to repair. Regardless, when he does start using CNC, I don't expect a steep learning curve. His views are already 10 times this channel, I 'll have to check Social Blade to see how Adam's endorsement affects subs and views. An unsolicited endorsement like this can really be a game changer, as they say.
@@andrewterry8092 How does Kurtis do it? Just like Adam used to do.
@@SteveColluns-hm2xx Yes, I agree (my comment about CNC was a bit sarcastic)...Palace of Pimp is spot on.
@longcaster At best, Abom is journeyman level, on a good day, with the sun shining, in a leap year! Kurtis is a master, his shop made tools rival the most expensive store-bought, often surpassing them! He never halfasses anything, unlike Abom. No wonder Adam Savage gave him a shout-out! If he was here in the U.S. and not Australia he would be a breakout star on Discovery for sure! And he is definitely not a wannabe lifestyle influencer like Abom!
Congrats on finally getting back into machining.
Can you program it to do your logo carve it out so to speak be a good practice?
Is this eventually the solution to the Keith Rucker stoker engine dilemma?
Low rpm. why???
