As a Tool & Die Maker, a common drill for me was a 17/32. There were countless days where I drilled perhaps 800 inches in 1 day with that drill. It was used every day! So several tens of thousands of inches could be cut before I even wanted to sharpen it again! Certain metal naturally breaks into little bits, others create long stringy chips. I'd only break my feed for the safety of myself by a chip getting too long. The most difficult part is getting the cutting edge down into the metal, once it's in and cutting, as long as the temperature remains within limits, there's no need to worry. This was a cool video! I learned something about CNC programming that I knew from manual machining all along.
Why is Mark so easy to understand?? While he was talking about G73, I realized we've been using the wrong pecking cycle in a machine for for a whole year or so now.
There isn't a big difference between G83 IJK and G83 Q-peck, but if you're concerned about cycle time, you should increase Q by the same amount you increase K. For example, if you increase K by 0.250, you should also increase Q by 0.250. This is because you're comparing Q.125 with K.250, which aren't the same. That's the way I see it, but I love your videos; you are a good teacher.
Excellent video... for the youngins who see this... don't badmouth old guys using full retract... you use full retract on tools that can't evacuate chips or tolerate heat well; to pull the chips out and expose the hole and drill to coolant. Runout in your system will tend to wallow the entrance to the hole more with full retract, but in some cases the full retract will give you a much tighter hole as chip binding and tool edge bugging are the primary cause of wallowing out the hole aside from runout, and worse, poor work holding. When you need super accurate holes, you generally drill slightly undersized and follow with a reamer....but as the man says the tool technology is getting awesome. Additionally full retract may be a solution if chip strings are wrapping around the drill shank and marring your part's finish.
I almost daily drill holes of Ø 2mm x 60mm depth (or more) in mold steel. G83 is a must for this purpose, the chips don't find the way easily to get out of the hole ,otherwise. Its a time consuming job and depending the mold, 20-50 holes give or take, cnc will drill for hours. The holes must be close fit, and that make things even more difficult. That > , That I didn't know, maybe will help me to speed up things. thx for the tip.
If you're that worried about cycle time, why are you peck drilling at all? Spend a little more on some carbide drills and save a ton of time on every hole.
Yea i've just had a go with deep water hole gun drilling, The stock materials we have are 800 N/mm^2 up to 1.1k strength so they are quite strong so it takes 10 mins to get down to 600mm. But im sure if we machined softer materials they would be way faster
What if i want to drill in predrilled hole on z-30 and wanna continue with longer drill to make z-45 but with pecking from z-30? (drill 3mm). As far im using ijk drilling but i cant change 1st move to z-30 feed too much.
I'm sorry to hear about your bad experience. Here are some hints for the future. Don't try to open up a small diameter pilot with a large diameter tool unless you've got the right feeds and speeds. Check your programming that you're hitting the right hole. If you have two holes with different diameters available, you definitely don't want to hit the small one by accident! Make sure you're using plenty lubrication. If you have a tool that can self-exert lubricant from the tip, all the better. Hope that helped.
could you to a video on arcs in the zx plane? like entering the work with a 1.250 radius with a 1/4 inch ball end mill go in a straight line for 20 inches and then exit at 1.250 radius and show how to peck this down without using a cam system.
Thanks for sharing those tips for dilling, and I got a question for you, can I use G83 code to do these kind of drilling, change the feed rate in different depth of drill. (to extend the life of dirll)
great video .. I'm using a Haas sl-20 .. G83 have I, J, K in the manual .. but the machine ignore the values. It's bugged in some software revisions, or its some parameter you must change? G83 z-50. Q1. R2. I15. .. ? Thatr supposed to do 15mm for the first peck? But its starts pecking from the return value.. whatever i type on I .. tried both positive and negative values.. . Also tried adding values for J and K .. but the machine don't care..
That joke actually illustrates a software design problem that really does exist. There are ways to address it, but it actually takes extra programming work around it, and is often overlooked before it becomes deeply embedded in a code library. You should wonder if this "anti-pattern" happens to exist in the CNC software you use.
With a 118 degree drill point, we can multiply the diameter by .3 to get that breakthrough tip length. So drill point length on a 1” 118° drill, is .3”
The X .3 rule just tells us how much deeper we must drill for the tool to reach full diameter, be ones of the drill point angle. What are you trying to accomplish?
I will have to look at the manual when I get back to work, but I don't think the g83 on my 15 year old VF4 has IJK options. Can I get software updates? Currently, I use multiple lines for each hole. A g81 followed by a g83 with an R value that does not pull the drill all the way out of the hole. It works, but the programs get long when making pieces with multiple hole circles since I can't use g70 with my method without losing any time saved to rapid back to each hole multiple times.
Hey bob , great content and have following since an year pluse by now, and we are about start our own shop with a vmc , I am bit confused with the different types of holders that I would want to by, because I don't what's going to come through that door after I set up , so can help me out with the different types of of holder in By 40 tapper , and their uses so that I can decide on what to buy and how many, it will be great if you make a video , that might help others also. Thanks a lot a keep going ,
u v girish - For a new machine I would start with the basic tool holders, then add some of the special holders later as needed. If you don’t know what kind of parts you’ll be running, I might fill a machine with: (8) ER32 x 4” Collet holders, (1) ER32 x 6”, (4) ER16 x 3”, (2) ER16 x 5”, (3) ½” Shank Weldon Holders, (1) 5/8” Weldon, (2) ¾” Weldon, (1) Precision Keyless Drill Chuck . You’ll also need a good indexable endmill to start with, 4 flute 1.25”/32mm is a good generic size, along with a 3” facemill/shellmill. ER collets are just good, universal holders, but you will need to buy collets. As your need for accuracy increases, you’ll find yourself buying a few hydraulic holders, in the specific size you need, and looking at some of the other holder options out there like Milling Chucks and Albrecht APC. Shrink Fit and Rego-Fix powRgrip systems are worth looking at as well, down the road. Check out our video on ER collets for more info, th-cam.com/video/WKikm6cQKh0/w-d-xo.html. Time to give your tool salesman a call! - Mark Haas Tip-of-the-day
Yes, this IJK pecking has been around for a very long time and should work just fine on your '93 Haas Mill. I spent thousands of hours on those mills, at the first shop I had worked at, great machines.
I was super confused when I saw x y i j in my gcode as i thought i and j were unit vectors and it didnt make any sense lol... Could you please let me know what book you referenced in the snippet you showed, this looks like a very nice reference for someone like me who doesnt know hoe to interpret gcode. Thanks
The G-codes vary from machine to machine and from make to make. Mazatrol will use g-codes but it’s specific to mazack. The biggest difference between EIA and mazatrol is incremental imput. There is a lot of information out there haas is normally the most user friendly. The machinists bible is a good place too start. It may make your eyes melt but it has almost everything in there.
I'm pretty sure I know the answer to this already, but would these G83 IJK Cycles work better for a wire sized hole? Talking maybe 1/16 or smaller. I do a lot of EDM blocks and I had to drill sizes that were about .030" Most of the time it's usually around 1/16" though.
Having a lot of personal experience drilling deep and tiny holes in a multitude of material types I would reccomend using g73 for those types of holes. I've had to do up to 65xDia depth holes before and G73 will save your ass doing those.
Hi. My name is Bernardo Dávalos. I'm a creo parametric user here un México. In my facility we have a 5 axis Hass and i want to know how or where can i take a five axis curse To programm this 5 axis hass. Excelent divice i Will put in practice
Flavio Puca - Tooling suppliers have some very specific drills, made just for circuit boards. I would contact your tool salesman, they would love to help find a solution for you. Sometimes, we are able to stack the material, and drill through many parts, firmly clamped together, into the fixture underneath. This can greatly reduce the chipping as the drill exits on glass-filled materials - Mark, Haas Tip-of-the-day
Steel type? Heat Treated? Drill material type? Desired hole depth? If Through coolant is used, you can just use g81. If you are just using a mild steel like 1018 and a basic HSS-Co drill and drilling about an inch deep, you can pretty much do this without a lot of fuss or effort. Something like S1000 F2. g83 q.25 z-1. should do the trick for small hobby machines / small shops. A lot of people have trouble drilling with small diameter tools, hope that helps.
Do you have any tips for drilling with large diameter (i.e. 1/2 inch and above) HSS drills? I was drilling a 1 inch deep through-hole with a 1/2 inch diameter drill bit (brand new from McMaster Carr) in 6061 aluminum with one plunge (since 1 inch is less than 4*diameter) and the bit seemed to scream a little bit. I later tried it using a 1/8th inch pecking full retract cycle and there was still a bit of screaming and strange noises. And sometimes a chip would get wrapped around the bit before it plunged for the next peck and it almost seemed like it was going to jam up. I had two steady streams of coolant flooding the bit and hole in each scenario. Would you want to drill progressively larger holes or is there another strategy to get better results?
Sounds like you are using a bad RPM / Feed to me. The bigger your cutting diameter, the slower it needs to go. If you aren't trying to drill a thousand holes a day or anything, and you'd rather prefer a clean hole wall I'd use 800 - 1000 RPM with a feed of 4ipm. So like, S1000 g83 z-1. q.400 F4. The reason why q.4, is because alum chips tend to get really stringy and need to be broken up to avoid a tornado of chips on the drill. Also breaking the chips up and doing a full retract with g83 will allow coolant to go in and prevent the aluminum from welding itself to the drill. Also, try drilling with an HSS-Co drill instead of an HSS drill. They will cut better and have better edge geometry.
@@Brokoro Thanks for your reply! I was using 3439 RPM at 20 IPM (on a 3.5 HP Matsuura Tiger) that I got from my HSM Advisor calculator, but it looks like that wasn't quite slow enough. I will try slowing the feed and speed down with the full retract cycle per your recommendation and see if I get a better result. Would a carbide drill cut much better than an HSS-Co drill (a carbide drill would obviously be a lot more expensive than an HSS-Co drill so if the results would not be much better than I would much rather use HSS-Co)?
pushparaj - They make them. It gets weird in a CNC machine though. Most drills like to feed at maybe .125mm per revolution, where an M6x1 tap must feed at 1mm per revolution to keep the threads nice. It’s possible though, you could use one feedrate for the ‘drill’ portion and another for the ‘tap’ portion. Fun stuff. - Mark, Haas Tip-of-the-day
@@Raja-kk1zi Pushparaj - It’s not practical for drilling and tapping into solid material. The deeper we go, we will need the regular flutes of the drill to evacuate the chips. For through holes (thin wall), it is very possible and it could save us a tool change. - Mark, Haas Tip-of-the-day
@@haasautomation Actually they make thread mills now that don't need a pilot hole even in steel and as an added bonus we were able to lower our sky high coolant concentration that we attempted to reduce small tap breakage in steel! Your videos are awsome!
High rpm and light feeds will not drill as deep of a hole without pecking as lower rpm and heavier chip loads. A heavier chip that is wire like comes out of the hole better than a thin chip that folds up and packs the flutes which causes friction (heat) and blocks coolant. A wiry chip allows some coolant to pass by and get down in the hole. Also, a heavier chip will not wrap around the drill and block the coolant and mar the part.High rpm also results in more heat and in a deep hole that is hard to get the coolant into that is bad. Sometimes by slowing the rpm down and taking the heaviest practical chip load possible you can drill to full depth without pecking, or get by with one peck instead of many. An example of "slow" winning the race.
Chad - Definitely. The new control has all the bells and whistles. The G83 cycle will also have the new chip-clean function as well th-cam.com/video/d1ATntHemHk/w-d-xo.html - Mark, Haas Tip-of-the-day
Ask your tool supplier if g83 peck is right for you. Stop using g83 peck if you experience strange chip formation or loose stool...oops I can't go on...Good on you Haas for the video.
For pepole that don't know this toolpath it's called desending peck drill in mastercam, I = Initial Peck, J = Descending Value, K = Final Peck. After playing with it and trying to simulate what it was doing in mastercam i tought it was a G81, but after pos processing it uses the G83 IJK cycle.
I love these tips and Mark is great but this tip does a disservice to those who use HSS drills. The main purpose of peck drilling is to get coolant in the hole to cool the chisel point. Heat destroys HSS. Chip removal is the second reason for peck drilling. For my applications a G73 will just pack the flutes and cause drill breakage. There is no new magic for drilling unless you can utilize TSC drills. I'm sorry to have to disagree with this tip because they are always so good.
I have used similar cycle with an old Deckel Dialog control and really speeds up the drilling with HSS drills without compromising the drill longevity. Materials used were mainly tool steels and with drill sizes over 5 mm (~0.2") 4-5xD for the first peck is easily managed and coolant will flow in to the hole with just plain old single nozzle setup.
I don't know how well dialed in your speeds and feeds are but making too light of a cut at high rpm will require more pecking and is harder on drills. Slowing the rpm down and taking a heavy chip load often eliminates the need for pecking, speeds up the cycle, and extends the drill life. It took me years to figure that out. Running the highest rpm on deeps holes slows you down because it requires more pecking and wears out or breaks more tools.
@@G53X0Y0Z0 Very true, speed is a tool's worst enemy. If your tool (almost any tool) is not lasting what you think it should, the first parameter to consider adjusting is your speed. Speed is what creates heat, heat destroys the tool. Always better to start out using the tool at the lower end of it's recommended surface feet per minute (SFM) or meters per minute if in metric, check with your tool supplier and make sure you are using the tool within their suggested parameters as well.
I thought we needed a Z depth as well even with ijk method. Wording seems as if G83 Z# Q# needs Z depth. While showing only G83 I# J# K#, with no depth.
Normally Post processors will put the Z after the g83 like you have in your comment. But most fanuc machines don't care as long as it is on the same line as the G83. But you are A-O-K with how you wrote it out.
When using regular coolant shooting out at the drill I want to point out something that some people may miss. If the coolant is not pointed below the tip of the drill it will be washing chips down into the hole and when the drill goes back down will spin on the chips and break a small drill. Or if the coolant is blasting at super volume and high speed and hitting the top of the workpeice it can blast chips down in some of them--because it has the same effect as if the coolant were pointed above the tip on the flutes. It took me a long time to figure out why small deep drills were breaking for no reason right after changing them.
I am reminded of Shawshank Redemption when Brooks gets out of prison after fifty years and he says The world went and got itself in a big damn hurry. LOL
Very good overview on the topic of chatter. I wonder - maybe I just don't know - why non periodic oscillation in speed and feed isn't used. To my understanding, positive excitation often comes from harmonic, periodic resonance. Thus, why not modulating the feeds and speed around a mean value? ... :)
Stefan - We call this SSV, Spindle Speed Variation. It is available on Haas Lathes (M38) and Haas Mills (M138).

SuperAWaC - Yes, those same IJK values will work with our G73 High-Speed Peck Drilling cycle, which can give you the best of both worlds.

As a 30 year enginerd, all things industrial and technology from the old reliable pencil paper and drafting tools. To hand tools in the shop along with mechanical timing cam packs, gears, bearing slides, etc. To tooling for HDDs, turbines, roller blades, aerospace, and communications, motorsports, mining, military, Powergen, oil gas, automotive, automation, software Internet, IT, electronics, MEMS, rapid prototyping, to the maker and small business through the advances in information technology and social media to be alive now is awesome. Time is the most precious resource and the ability to maximize advances like using TH-cam to share across the world is a huge benefit for improving life skills that provide lessons that took me a long career to accumulate while today if i didn't have to spend years being lucky enough to have the opportunity of working with a great group of well-seasoned veterans to get tips like this. They had catalogs they generated thousands of tips they figured out or some old timer taught them. It was your responsibility to create your own book to glean from the guys retiring they were happy to share but some were not. So if you figured something out that eliminated issues like knowing your best goto for a supplier or manufacturing process. The difference over time is if you are making the company money and being awarded appropriately while taking on learning more and become a mentor and leader that attracts talent. If it's toxic recognize issues if integrity is in leadership for performance based on many attributes. Burnout will be less and group motivation is self-feeding. It is important to diversify your skills across all areas.

There isn't a big difference between G83 IJK and G83 Q-peck, but if you're concerned about cycle time, you should increase Q by the same amount you increase K.

Yes, this IJK pecking has been around for a very long time and should work just fine on your '93 Haas Mill. I spent thousands of hours on those mills, at the first shop I had worked at, great machines.
Which book is that 4:35
How does this come into play with a center drill or spot drill and a regular HSS or TiN drill?
Unless you are working with strong, dense, or heat treated materials you really shouldn't need to be pecking your spots or center drills.
Can we also use G83 in turning centers?
I was super confused when I saw x y i j in my gcode as i thought i and j were unit vectors and it didnt make any sense lol... Could you please let me know what book you referenced in the snippet you showed, this looks like a very nice reference for someone like me who doesnt know hoe to interpret gcode. Thanks
The G-codes vary from machine to machine and from make to make. Mazatrol will use g-codes but it’s specific to mazack. The biggest difference between EIA and mazatrol is incremental imput. There is a lot of information out there haas is normally the most user friendly. The machinists bible is a good place too start. It may make your eyes melt but it has almost everything in there.
I blind drill M42 tool steel, no pecking at all. Carbide drill, through tool coolant and a nice feedrate.
Can we use a G73 on a non High Speed Mill? Or it’s only for High Speed machines?
Jorge - The cycle will run on machines, even if they don’t have the High Speed Machining Option. - Mark, Haas Tip-of-the-day
Such a good teacher. My new Haas lathe is much to due to your videos. Thank you sir. Thank you to Haas.
Solidworks CAM has this ability but no where have I found a way to set I,J,K for a HAAS.
Very interesting and informative. Too bad I don't even own a cordless drill lol.
I'm pretty sure I know the answer to this already, but would these G83 IJK Cycles work better for a wire sized hole? Talking maybe 1/16 or smaller. I do a lot of EDM blocks and I had to drill sizes that were about .030" Most of the time it's usually around 1/16" though.
Having a lot of personal experience drilling deep and tiny holes in a multitude of material types I would reccomend using g73 for those types of holes.
I've had to do up to 65xDia depth holes before and G73 will save your ass doing those.
Sir this cycle can use only HASS..... Or can use another serious, for an example fanuc...
u can use it in fanuc machines too
Hi. My name is Bernardo Dávalos. I'm a creo parametric user here un México. In my facility we have a 5 axis Hass and i want to know how or where can i take a five axis curse To programm this 5 axis hass. Excelent divice i Will put in practice
Hola trbajo perforando material de circuitos impreso y tengo problemas de dispercion en agujeros de 0.50
Flavio Puca - Tooling suppliers have some very specific drills, made just for circuit boards. I would contact your tool salesman, they would love to help find a solution for you. Sometimes, we are able to stack the material, and drill through many parts, firmly clamped together, into the fixture underneath. This can greatly reduce the chipping as the drill exits on glass-filled materials - Mark, Haas Tip-of-the-day
what would you recommend for an .098 drill (number 40) in steel?
What type of Steel? Do you have coolant through? If so, what coolant pressure do you have?
Steel type? Heat Treated? Drill material type? Desired hole depth?
If Through coolant is used, you can just use g81.
If you are just using a mild steel like 1018 and a basic HSS-Co drill and drilling about an inch deep, you can pretty much do this without a lot of fuss or effort.
Something like S1000 F2. g83 q.25 z-1. should do the trick for small hobby machines / small shops.
A lot of people have trouble drilling with small diameter tools, hope that helps.
Sir Plz All Programs used in G21 mode (mm)
I have a note on my desk to remind me of this! Thanks. More than half of our users run their machine in Metric Mode. Thanks for the comment.
Do you have any tips for drilling with large diameter (i.e. 1/2 inch and above) HSS drills? I was drilling a 1 inch deep through-hole with a 1/2 inch diameter drill bit (brand new from McMaster Carr) in 6061 aluminum with one plunge (since 1 inch is less than 4*diameter) and the bit seemed to scream a little bit. I later tried it using a 1/8th inch pecking full retract cycle and there was still a bit of screaming and strange noises. And sometimes a chip would get wrapped around the bit before it plunged for the next peck and it almost seemed like it was going to jam up. I had two steady streams of coolant flooding the bit and hole in each scenario. Would you want to drill progressively larger holes or is there another strategy to get better results?
Sounds like you are using a bad RPM / Feed to me. The bigger your cutting diameter, the slower it needs to go.
If you aren't trying to drill a thousand holes a day or anything, and you'd rather prefer a clean hole wall
I'd use 800 - 1000 RPM with a feed of 4ipm.
So like, S1000 g83 z-1. q.400 F4.
The reason why q.4, is because alum chips tend to get really stringy and need to be broken up to avoid a tornado of chips on the drill. Also breaking the chips up and doing a full retract with g83 will allow coolant to go in and prevent the aluminum from welding itself to the drill.
Also, try drilling with an HSS-Co drill instead of an HSS drill. They will cut better and have better edge geometry.
@@Brokoro Thanks for your reply! I was using 3439 RPM at 20 IPM (on a 3.5 HP Matsuura Tiger) that I got from my HSM Advisor calculator, but it looks like that wasn't quite slow enough. I will try slowing the feed and speed down with the full retract cycle per your recommendation and see if I get a better result. Would a carbide drill cut much better than an HSS-Co drill (a carbide drill would obviously be a lot more expensive than an HSS-Co drill so if the results would not be much better than I would much rather use HSS-Co)?
Hey bro ,I got a doubt and what are the problems of combining a drilling and tapping in a single tool.
pushparaj - They make them. It gets weird in a CNC machine though. Most drills like to feed at maybe .125mm per revolution, where an M6x1 tap must feed at 1mm per revolution to keep the threads nice. It’s possible though, you could use one feedrate for the ‘drill’ portion and another for the ‘tap’ portion. Fun stuff. - Mark, Haas Tip-of-the-day
@@haasautomation so it's not recommended for drilling and tapping? Right! And what happens if the drill speed is used along with drilling!
@@Raja-kk1zi Pushparaj - It’s not practical for drilling and tapping into solid material. The deeper we go, we will need the regular flutes of the drill to evacuate the chips. For through holes (thin wall), it is very possible and it could save us a tool change. - Mark, Haas Tip-of-the-day
@@haasautomation ahmmm....thank you!! And i would like to look into it more!!!
@@haasautomation Actually they make thread mills now that don't need a pilot hole even in steel and as an added bonus we were able to lower our sky high coolant concentration that we attempted to reduce small tap breakage in steel! Your videos are awsome!
High rpm and light feeds will not drill as deep of a hole without pecking as lower rpm and heavier chip loads. A heavier chip that is wire like comes out of the hole better than a thin chip that folds up and packs the flutes which causes friction (heat) and blocks coolant. A wiry chip allows some coolant to pass by and get down in the hole. Also, a heavier chip will not wrap around the drill and block the coolant and mar the part.High rpm also results in more heat and in a deep hole that is hard to get the coolant into that is bad. Sometimes by slowing the rpm down and taking the heaviest practical chip load possible you can drill to full depth without pecking, or get by with one peck instead of many. An example of "slow" winning the race.
dumb question does IJK work on the last gen control?
Chad - Definitely. The new control has all the bells and whistles. The G83 cycle will also have the new chip-clean function as well th-cam.com/video/d1ATntHemHk/w-d-xo.html - Mark, Haas Tip-of-the-day
Ask your tool supplier if g83 peck is right for you. Stop using g83 peck if you experience strange chip formation or loose stool...oops I can't go on...Good on you Haas for the video.
How can you make a G83 IJK in mastercam?
For pepole that don't know this toolpath it's called desending peck drill in mastercam, I = Initial Peck, J = Descending Value, K = Final Peck. After playing with it and trying to simulate what it was doing in mastercam i tought it was a G81, but after pos processing it uses the G83 IJK cycle.
I found what was the issue.
Plz update more videos
Hello Mark. Great video. Where can i buy a shirt like yours ? I drive a VF-7 and it would match perfectly.
Is this function available in Vf2 also
I love these tips and Mark is great but this tip does a disservice to those who use HSS drills. The main purpose of peck drilling is to get coolant in the hole to cool the chisel point. Heat destroys HSS. Chip removal is the second reason for peck drilling. For my applications a G73 will just pack the flutes and cause drill breakage. There is no new magic for drilling unless you can utilize TSC drills. I'm sorry to have to disagree with this tip because they are always so good.
I have used similar cycle with an old Deckel Dialog control and really speeds up the drilling with HSS drills without compromising the drill longevity. Materials used were mainly tool steels and with drill sizes over 5 mm (~0.2") 4-5xD for the first peck is easily managed and coolant will flow in to the hole with just plain old single nozzle setup.
I don't know how well dialed in your speeds and feeds are but making too light of a cut at high rpm will require more pecking and is harder on drills. Slowing the rpm down and taking a heavy chip load often eliminates the need for pecking, speeds up the cycle, and extends the drill life. It took me years to figure that out. Running the highest rpm on deeps holes slows you down because it requires more pecking and wears out or breaks more tools.
@@G53X0Y0Z0 Very true, speed is a tool's worst enemy. If your tool (almost any tool) is not lasting what you think it should, the first parameter to consider adjusting is your speed. Speed is what creates heat, heat destroys the tool. Always better to start out using the tool at the lower end of it's recommended surface feet per minute (SFM) or meters per minute if in metric, check with your tool supplier and make sure you are using the tool within their suggested parameters as well.
Can apply on fanuc control
I don't understand how to machine know drill depth ?
G83 used in turning cnc lathe machine
The SS stands for Super Sport, liscenced by Chevy
SS stands for something else in Germany
There is the G73 with Q and K value...a combination of a G83 and G73...
Where can I get one of those shirts? Who makes it?
Directions unclear, got steak knives stuck in my tool holders.
I thought we needed a Z depth as well even with ijk method. Wording seems as if G83 Z# Q# needs Z depth. While showing only G83 I# J# K#, with no depth.
You still need the Z depth value. It was just passively implied.
Why u r using
4D,2D,1D
Why u don't take any other values
Is it relates with your component or tool dimen.
If any 1 know plz explain
I use a G73 q .05 and add a k .150 so it breaks up the chip and brings it up after 3 breaks
i would definitely be happy if u explain that frog joke??but cool explanation MR.THICK HEAD lots of love from INDIA
Excellent video thanks for sharing !!!
Good job explaining that, cheers!
sorry where is the total depth do I go G83 Z-2.0 I.5 J.125 k .05
Normally Post processors will put the Z after the g83 like you have in your comment. But most fanuc machines don't care as long as it is on the same line as the G83.
But you are A-O-K with how you wrote it out.
When using regular coolant shooting out at the drill I want to point out something that some people may miss. If the coolant is not pointed below the tip of the drill it will be washing chips down into the hole and when the drill goes back down will spin on the chips and break a small drill. Or if the coolant is blasting at super volume and high speed and hitting the top of the workpeice it can blast chips down in some of them--because it has the same effect as if the coolant were pointed above the tip on the flutes. It took me a long time to figure out why small deep drills were breaking for no reason right after changing them.
I am reminded of Shawshank Redemption when Brooks gets out of prison after fifty years and he says The world went and got itself in a big damn hurry. LOL
Dear sir plz provide programing manuals in pdf
Gracias, buen trabajo, me ahorro bastante tiempo en ciclos preprogramados
With the I-J-K do I have to use G98 ?
George Papadimitriou Yes, with I J K you have to use G98 or G99 as your choice for drilling the other holes with 'Z' initial value or 'R' value.
Thank you
Now i was told peck drilling helps keep drills from walking especially longer drills? Is this true
Very good overview on the topic of chatter. I wonder - maybe I just don't know - why non periodic oscillation in speed and feed isn't used. To my understanding, positive excitation often comes from harmonic, periodic resonance. Thus, why not modulating the feeds and speed around a mean value? ... :)
Stefan - We call this SSV, Spindle Speed Variation. It is available on Haas Lathes (M38) and Haas Mills (M138). Our Servo control systems are also tuned to avoid certain frequencies, on different machine models, based on their natural frequencies. - Mark, Haas Tip-of-the-day. Check out th-cam.com/video/dXR2wDDFFm4/w-d-xo.html
please teach us about polar coordinate G16 drilling cycle
no.
I'd call for the steak knives, but there wasn't a flashing number in the bottom of the screen...
Just use solid carbide thru coolant and drill it in one go use tool life on machine job done.
Can I use IJK with G73?
SuperAWaC - Yes, those same IJK values will work with our G73 High-Speed Peck Drilling cycle, which can give you the best of both worlds. The drill, with a G73, will back up slightly with each peck, but won’t retract all the way out of the hole. - Mark, Haas Tip-of-the-day. For more info, download the Haas Mill manual from our website, www.haascnc.com.
Sir your lecture is good. Pleas send some milling programs in Simone
no.
knowing me I'd try that command and all of a sudden the machine would start helical plunging with a 1/4" drill bit
It doesn't get rid of the chips in the hole
Thank you very much for your helpful videos
First peck 2.5D use G73, second peck use G83 with dowel,I made a G66 custom macro 😂
I’m no longer a sales rep but Cutco is pretty damn good 😂😂😂
As a 30 year enginerd, all things industrial and technology from the old reliable pencil paper and drafting tools. To hand tools in the shop along with mechanical timing cam packs, gears, bearing slides, etc. To tooling for HDDs, turbines, roller blades, aerospace, and communications, motorsports, mining, military, Powergen, oil gas, automotive, automation, software Internet, IT, electronics, MEMS, rapid prototyping, to the maker and small business through the advances in information technology and social media to be alive now is awesome. Time is the most precious resource and the ability to maximize advances like using TH-cam to share across the world is a huge benefit for improving life skills that provide lessons that took me a long career to accumulate while today if i didn't have to spend years being lucky enough to have the opportunity of working with a great group of well-seasoned veterans to get tips like this. They had catalogs they generated thousands of tips they figured out or some old timer taught them. It was your responsibility to create your own book to glean from the guys retiring they were happy to share but some were not. So if you figured something out that eliminated issues like knowing your best goto for a supplier or manufacturing process. The difference over time is if you are making the company money and being awarded appropriately while taking on learning more and become a mentor and leader that attracts talent. If it's toxic recognize issues if integrity is in leadership for performance based on many attributes. Burnout will be less and group motivation is self-feeding. It is important to diversify your skills across all areas.
In love with kennametal go drills
Hass' videos are really well done!...how? Who's doing the scripts? 🙂
Abinesh Chandrasekhar - Thanks. We have a number of
different people making videos. The scripts are usually a collaboration between
the on-screen Engineer and the person filming (Videographer/Editor/Producer).
On complex topics, we’ll get feedback from the Engineering, Applications, Service,
or Software Departments. Thanks for the comment. - Mark, Haas Tip-of-the-day
So did you save the time by doubling the depth of the pecks or by less pecks? Or both?
