Study that G and M code as much as possible. While it runs, watch what it does, the moves it makes. Google the codes you want to know. Learn what they do. Print a cheat sheet out. It's what separates the operators from the machinists. Thanks Titan!

Titan I have a similar story to yours. I’m from flint mi. Got a 8th grade education. Got locked up for 2 years. That was over 30yrs ago. Got into machining from a guy in AA. The trade changed my life. Your doing a great job. Keep up the great work.

Not too shabby! At the risk of being a troll, I need to point out that you're confusing the terminology "sub program" and "sub routine". You correctly identify the requirements for M98 sub programming, but you're also calling the M97 callout as a sub program, where that is actually a sub routine. By correctly identifying the sub structure, it is much easier to understand whether the additional code should reside within the source program or externally. Keep up the good stuff!

I learned the trade doing manual work but I can say that in this day and age expert CNC programming is a must, and crucial to being a must have employee in just about any shop. I understood your program as you explained it. Good stuff Titan. I am becoming a big fan. If I was 20 years younger I would be knocking on your door everyday until you let me in.

Titan! Awesome video! I program 2 Mitsubishi CNCs. Your style of keeping the code clean is exactly like I do. I'm obsessed with this style of coding. Also I work making parts, not molds, and never can use CAM for this type of machining. Thank you very much. Cheers from Argentina. Thumbs up for Titan!

The real beauty of M97 is all your sub-routines stay with the Main Program when you write them back to where ever you save/archive your programs!!!

You can add to that another sub with a ball endmill. This sub would have ZX motion with minimal Y stepover and smooth the surface. Boom..!

its so hot to see technical industry stuff in an entertaining way, love it

Titan, I am building a custom machine for CNC machining glass for a customer. I was teaching this technique to one of their techs just this past weekend, thanks for posting, now they can watch it over and over and practice

Boom! This was awesome! Keep this type of content coming. It like visiting a friends shop on lunch and picking up a new trick.

Used to do stuff like this decades ago (before all the cool CAM systems). Nice to see people still do this kind of stuff. Thanks!!

I know nothing about CNC etc but since I started engineering and even before I always had the question of ''How do the people make all those complex shapes and how do they program all these robots ?'' But I have to say that I hugely appreciate and respect people who work in manufacturing and make things come to life and often having pressure from the designers etc.. You are a true Professional Sir !

Nice tip, I am gonna try that one tomorrow. Gotta make some sort of rake tooth gadget. But I do prefer the g53 to the 91/28 bit, being on a Haas mill.... UPDATE: I left the initial comment over a year ago. I use this constantly now. Not only the incremental stuff but the sub routines. I never use the G54 in front of the M97. I recently made a BUNCH of closer tooling for my company for pressing the internal bore rings on the composite material for making automotive head gaskets. We don't have a cnc lathe (a small import lathe the owner of the company bought years ago to polish crankshafts with lol) so I had to get creative on how it was done. Closer tooling fits on a small press with a "toolholder" with a 1" bore you stick the shaft into and lock it down with a set screw. The closer was designed to close a 3.56" bore ring. Shaft was 1.75" long. I was using a 2" sq shoulder face mill on a 4140 billet sized 4" x 4" x 2.5". X & Y was picked up dead center of the billet. G0 G90 G54 X0. Y3.5 ... G01 Z-0.05 F100. M97 P1 L34 .... N1 G01 Y2.5 F60.; G02 X0. Y2.5 I0. J-2.5; GO1 Y1.5 G02 X0. Y1.5 I0. J-1.5 G01 Y3.5 G01 G91 Z-0.05 G90 M99 The cut took about 15-20 minutes to remove a TON of material. Spinning the cutter at 1250 rpm left a very, very good finish. Done on a Haas TM1, circa 2006.

It’s old but when I viewed this I remembered looping from years ago, it’s been awhile. Thanks Titan!!! Modified it to do something different but close enough!

It's good you show this! We use this kind of programming very often, saves a lot of time and I find it very easy to do with HEIDENHAIN. I really love the fact you're teaching this, and now I know a thing or two about 'normal' gcode too! Keep up the good work and greetings from the Netherlands!

This is great stuff!!! I absolutely LOVE the way you teach and explain how to do this!! Not only are you a master machinist you're a great teacher as well!!! Love it

When you get good at doing simple L repeat sub-routines, you can start experimenting with conditional statements and let the control calculate how many times to repeat the sub-routine. For example, you can use a WHILE [#3 LT #30] execute a sub-routine or a sub-program. The control will repeat the sub-routine as long as variable #3 (my Z depth variable) is less than #30 (my finish Z level). This format works with Haas and Fanuc controls that have macros enabled. It's been several years since I've written macros, but I have used them to automate thread milling and pocketing with tapered walls. WARNING!!! this is high level programming and like Titan said, you can really crash your machine badly if you don't dry run you new sub-routine very carefully!!!

Thanks for the great video Titan. As a 30 year manual machinist, I am now teaching myself CNC programming from the good old HAAS manual and videos like this. I recently used M97 for a program, but could have saved time with the techniques in this video. I can't wait to give this a shot!

I run two fanuc turning centers with live tooling. I adapted a helix milling and flats milling macros into gcodes. I also do custom macros on the fly for repeating features at different angles. Lot of the older guys did not like this at first, but it made things so much easier to program.

Awesome video and perfect timing. I've just started to teach myself Macro/ Sub programming. Some of our controls have memory space issues, so figuring out Subs was essential.

Great video titan I'm actually at the point where I understood what you were doing as you were typing it thanks for sharing that was fantastic

Thank you for this video and others like it! As a relatively new machinist, I have been breaking away from some of the slow conventional methods I have seen and been taught thus far. Your content gives me inspiration that I apply at work; I recently received a large pay increase as a direct result of me cutting cycle time drastically by applying high-speed techniques. My eyes are being opened and I am seeing how much these tools can really take! My finishes are even improving as well since I am having more consistent tool pressure with a good chipload and less vibration and better heat dissipation. Fortunately, the more experienced machinists I work with have been very kind to me in their acceptance of my way of doing things. Worrying about stepping on toes seems like a sure way to limit my potential though, so thanks again!

Used it many times. A time saver.Tool change is one I like. Have seen so much time lost in tool change.

Great video Titan. I would love to see more videos of you interacting with the controls and showing us more tips . Thank you for your knowledge. It is very much appreciated.

Love these tips videos, I now use the invisible stop all the time!

I teach some CNC at a high school, lucky enough to have a HAAS. I am no pro, but I love it. I learn alot from your videos .THANKS! My students don't know why I say BOOM so much :')

I use M97 and M98 to Create menus out of my codes. For Example making 1-2-3 blocks, i used M98 on a Fanuc machine to jump to each individual side to drill and tap my holes and because all of my codes were at the top and the line after each M98 was an M01 so i could stop the program and select whichever side i liked! I love Programming like this and here is an example of what i mean. (Side 1) /M98 P1; /M01; ; (Side 2) /M98 P2; /M01; ; /G91 G28 Z0.; /M30; Second set of end codes at the bottom so if i tun on block skip i skip my menu and run the program like normal for less experienced machinists. Hope you guys find this interesting!

Thank you for this! Ya make understanding machining pretty easy. Will definitely be utilizing this very soon!

I think manual coding videos like this are extremely helpful. Not just for new programmers but for guys like me that use use a refresher..keep this comin! Thanks

Great stuff use this daily, can loop sub programs to do pretty much anything using loops.

That was awesome!😁 Sweet method! You know I'm trying that when I get back to work next week!😂

I have used this hand programming method a zillion times, and there are many times it's easier than using cad simply because it can be quicker, without having to draw and then write a path, download, etc. Especially handy for one off stuff. I also use it with any shape, circles, and some simple curves etc. Just remember to take his advice on G90/91 issues. Run above the part first! Good video!

Mate! Cnc shop I worked at, was running for years without subs, programs a mile long on repeater parts... I reprogrammed everything with subs... Everything is so much easier to adjust. 40 parts on a jig.. female 36mm between flats hexagon,fully deburred, 4 holes on the OD, chamfered and back chamfered. 1 main program, 5 subs.. done. Boom.🤘

Great tutorial , Titan has big heart

Awesome video Titan sir, Keep posting such Fantastic contents and I would love to see a separate playlist for advanced manual programming G and M codes. Waiting for more such interesting contents ahead thank U 🤘BOOM

Great video, Not many videos out there in this much detail. I like to use helical cycles when I program on the haas machine. Program below is an example of a 20mm hole using the loop system on haas control to mill a hole (won’t work on Fanuc machine) (Helical milling); G00 G17 G21 G40 G49 G80 G90; G53 Z0; T1 M06 M03 S15000; G54 X Y ; (x & y being the centre of the hole you want to mill) G43 Z50 H01; G01 Z2 F4000; G91 G41 D01 X0 Y10 F6000; G02 Z-2 X0 Y0 I0 J-10 L31; G02 Z0 X0 Y0 I 0 J-10; G90 G01 G40 X Y;( x&y being the centre of the hole you want to mill) G00 Z50 M5 M8; G53 Z60; G53 X-750 Y0; M30;

Nice job titan i love the vids keep em coming one day i will own my own shop im determined to be able to give my kids the life they deserve thanks for all you do

Amazing trick! Titan please make a video about how to achieve 3D surface smoothness when machining with ball end mills!

Absolutely great I am CNC machinest And i operate CNC optical profile grinding,,,and the machine is waida,,,, I put program is only, radius,line,champer, y,x.f. but G code i never use thats why i want learn more,,, actually my machine is 5 axis x,y,z,c,b, your machine and your tutorial is very good and gave a lot of information from you sir,,thank you more blessings and God bless you Always watching #philippines

you are outstanding me and my brother went to Hass open to day little BOB showed us your site wow we have struggled for years and argued over the running of these machines

Great little video!👍, glad it’s not just me that likes to keep things clear by throwing in some EOB’s, Nothing worse than trying to trawl through a program that’s all bunched together. Look forward to your next vlog. 👍

Great video, this is stuff I wish I would have learned in school. I was just starting to get the knack of running and tweaking when I had to leave to take care of my baby boy. I feel so rusty now...

I always enjoy watching it. I am using haas machine vf-2 vf-5 ec400 in Japan. It's a very motivating video that I use for my work. boom! boom! boom!

NIce video, I did never used the M97 and I think I will love it

Please keep bringing manual programming. I have a lot of catching up--- I spent 15 years in prison. It's really tough to compete with people that have a better understanding--- and my criminal record prevents me from getting the top or any job. Thank you so much!

Back in the day, i used to use a sub incr z+, prog loop, works a treat, in heidenhain, or m98 /m99 also incr scale factor to produce pyramids, you can work out the tangent and create the x/y stepovers to create the angle, also linear polar and angles can do loads for way less code, just link the subs together Most Miller's would have a bunch of subs tucked away This was back when cad was only used for more advanced profiles

Thanks for the great lesson!

I use this a lot. So quick and handy!

Titan - master of machining Simple and easy way how to ramp 45 degrees like it !

Very Nice. I'm always doing manual part programing for just like this, conical shape cutting, 3D "V" shape in segmental of circle, spiral grooving, part of circular segment with variable depth, scroll grooving etc. etc.

Great video! I use the same process when I do cnc broaching of keyways on a HAAS VF4SS. today I learned something new. Thanks! TITAN GILROY I'm a big fan.

I use the hell out of sub programs and macros on the G code machines. On the hiedenhain controlled machines I use Q parameters. What you just did you could do in 4 lines with hiedenhain. It's super powerful.

Love from India 😍❤️ u r awesome

love every single video on your channel. i wish you would do some more lathe videos though :) but mill is good knowledge too. One of the coolest channels on youtube BOOM BOOM BOOM!!

Haas' use of M97 is and has always been a fantastic feature. Try using G52's for multipart positioning, incorporating M97's for the subs. In other words, you can either hand program or use cam for the subroutines and position multiple parts with just one work offset(G54-G59). I've set up jobs with over 250 parts on a 4th axis tombstone, sitting in a vertical haas this way.

Awesome little snippet. Your dedication boosts my confidence everytime I see your videos. BOOM! Just a though: Ramping Z will add better finish and shallow scallops.

Hello from Romania! GREAT video Titan, I was very excited to discover M97 on HAAS :D I usually use variables on haas and fanuc machines and do the same thing So the program will looks like: M6 T1; G00 G90 G54 X-0.325 Y-3.75 M3 S12000; M08; G43 H1 Z0.1; #1=-2.25; (Z START POSITION) #2=-0.325; (X START POSITION) N1 G00 G90 Z#1 X#2 F100; G01 G91 Y4.25 F300; #1=#1+0.05;(WARNING INCREMENT NEED TO BE SUBDIVISION OF Z FINAL POSITION) #2=#2+0.05; G90 Z#1 X#2; G91 Y-4.25; #1=#1+0.05; #2=#2+0.05; IF [#1 GE 0.05] GOTO 1; (Z FINAL POSITION 0.05 above the surface) G00 G90 Z0.1 M9; M5; G28 G91 Z0.;( BOOM!) M30;

Just starting this coarse and I would like a playlist from beginner to advance

Although i am not good at English but you explain quite clear thank you so much.

I have used macros to do something similar, except it milled a conical chamfer on the top of a bore with a ball end mill, and the angle was specified for the macro. The G91 is the perfect way to do many different ops with very little code.

Happy to be with you guys.

This technique is used on the turret punch press machine in our shop to repeat features with an incremental shift to make a bunch of parts on a piece of sheetmetal. Controller is a bit older though, LOL. 1984 FANUC GN-6.

I sure do appreciate you Titan. I practice Fusion 360 daily. I watch your videos and other machining videos. You add value to the whole country. God smiles on service to people. God bless you.

Great video awesome tip! Hey I just picked up an Mlock vise from ASI Mechanics. Wicked fast setup and 12,000lbs clamping force BOOM!

Nice video as always. :) I'm now a Heidenhain guy. I make programms only by hand. The subs are the best way to make programming easier. I think you can have a video about macros (on HH Q parameters). The whole world changes with them. On the older HH CNC234 (20+ years old) I make nearly all the cycles that my TNC640 have by hand programming, with subs and macros for 4 axis and I can do helical milling and ramping with only few lines of codes. I don't know how it works now on Haas controller because it was 3 years ago I last worked on a Haas but on a the Fanuc basis controllers I'm working on (NCT for examlpe but if I remember right Fanuc can do it, but I need to check it) I can use "I" before the axis letter and don't need G91. It is a more safer way. For examlpe IX, IY, IZ and so on.

Super bro tq for your technic manual program ❤️👍

That works well on a lathe if you have multiple sized spacers you can use sub programs

Use same formula with a G13 for boaring a hole or pocket with I,J,L and Q...(depending on application) 1 line 1 hole or pocket minus tool pickup, homing lines, ect. Great time saver for any machine use it a lot

Superb Titan, give me a shout if you're ever over in the UK or thinking of starting up in the UK...lol!! Would love to work for you. Keep up the good work😉👍

Great job brother, I teach at a University and I would love to take some training with you! Very similar style, meat and potatoes.

I’ve been running Kuraki HBM for 15 yrs now. Can you make a video using any of your Horizontal Boring Mills? Love to see how you guys demonstrate any sort of Cogsdill U axis heads for contouring. By the way, I just found your channel 2 days ago and subscribed. I’m a fan! Titan, keep up the great work man! Cheers from Houston,TX 🤘🙂🤘

Hey titan it’s me again! I really enjoy your videos, and I found a HAAS vf3! It’s been great so far but I’m only set up for 3 Axis parts right now. I’m wondering what is your best and fastest multi vice, multi operation set up and tips! Thank you.

Man, i wish i could afford to get lessons . I like this kind of stuff.

Awesome, great video.

Great teacher.

very informative,thanks a ton!

I run wire EDM machines and use sub programs quite often. We made fixtures for machining multiple parts one after another, and my predecessor used to program the fixture in one long string with the CAM software. 10 or more parts in one long program. Just program it once, move over, and run it again, boom! 😉 It's a whole lot easier to follow that way, and if you have only a few parts left to do (and you're not going to be around) you can VERY quickly stick in a stop so you don't waste wire machining thin air (water)

The god among the cutting machine operators. 💪

Titan! Please! Do more tutorials like this. When you dont have to make difficult part in cam and / or you dont have time to sit and do it in CAM in office.. Just by hand fast and efficient.. Many of us have kinda simpler parts than that aero space which are insane! Appreciate the vid! soo cool!

sorry to comment on such an old video, but i recently used this added in some some common variables and can chamfer about any size material by changing my VC's (I'm an okuma guy) great vid

This is a great trick and useful for learning sub programs. Are going to do any video about how to use sub programs for multiple parts with M97 and G154? It would be awesome to learn.

Ive been working in a machine shop for 10 years now and i thought i wanted to do something new but now since watching your videos ive taken it upon myself to re organise machine areas and seek the fastest most efficient way to machine parts, nothing will compare to your absolute perfection of a machine shop but every little bit helps at work thanks mate

I like your video. Good explaining 👍🏻👍🏻

I work on a fanuc machine so instead of a M97 i use a while loop instead of a M98, the beauty of the while loop is that you can increment variable values using X#1 Y#2 and z#3 making it a very powerful technique to use

Good video Titan 👍 I teach my guys to use a sub for safe start and another for safe end so like M98P1 safe start M98P2 safe end Both progs the same but P1 leaves table where it is P2 parks table at load position or door. Sub should have all you cancels in even mirror and rotation and G52 X0Y0Z0 G40 G90 M9 if you follow. So then at the start it M98P1 Call tool and all that Then cycle or whatever M98P2 M30 BOOM 💥 best to use P8001 & P8002 so you call lock it out so it can’t be changed with the parameters. It’s good with 5Axis as well. Keep it real my man! 👊

After I started programing with Macros by hand, there is very little I need to do in the CAM apart from the very complex parts. I love to make programs in the machine and learning Macros was the very best thing I did, it makes your like A LOT easier. Trully recommend to everyone.

Excellent work. Boom boom

i like the subs i used them when doing alot of drilling you can use the subs to break up tapped holes and counterbored and thru holes in different subs lots of copy paste and i also used G91 and broached in the mill locked spindle and up and down in Z stepped over in X or Y

You and your son explain so well. Most people have to be machinist to understand why we explain some in detail. The way I program starts either how I start and end my programs. I make sure I stick to that so I notice if I did some wrong there. Because I have seen people mess up at the start or end. I like to get the machine going on the first line. I. The first line I turn on the spindle and make it go to the first position where I begin my approach. I like to use EOBs to to separate the slots pockets or holes. And I name them to if I the measurements are going to be different. You must have been very good with your son Sir. I remember when my dad got me hired at 9.50 I thought this was going to be easy money where I could play all day. At just 3 months he made me load programs by hand instead of the easy way. Can you programs bolt circle patterns and maybe some boring a holes to a certain diameter and explain the math. I want to have those in a folder. Figuring out Bolt circle patters t he hard way is something I still struggle with.

Excellent so nice videos i love it

Probably best programming video you’ve released yet!

Live these vids you do titan give me a good insight into what I can do better at with myself when I'm machining, BOOM brother 👍

Make it parametric so that it can be used in more situations. Or should I do it and post the code here?? And you can explain it later

I'll just like the way you explain.(from Tijuana)

Awesome.. i programmed apple computers in elementary school. To do this in the 1970s it dawned on me the relation , if then statements too. Similar concepts.

It would be great to see the material being cut alongside the machine control. Then we can follow along with the coding.

Ahh your sub program is a label on Heidenhain which I programme and operate! We can also write complete different programs and also call them up in a singular programme! Very enjoy these videos keep up the good work!😊

Such easy steps you can also create without sub, symply install a Counter(by example #1), if you don`t want to have a lot of small subs after the PGM END. ; #1=0; (Reset counter, number NOT used by anything else) N666; (Jumpmark) G91 ......... ; xyz; xyz; #1=#1+1; IF[#1 GT 23] N555; GOTO N666; N555; (Jumpmark) ; ; Works with every NC, only little changes in writing #=/ VC=/R=/Q= etc. etc. ; And I agree totally with you: only if you are able to read the NC you can shine at the CAM Greets from Switzerland

Thank very much sir

brother publishes a good table to locate revolution and advance depending on the blade and the material please, gong video thank brother
