HOW TO USE AN M98 TO CALL SUB PROGRAMS ON A CNC MILL

This video shows you how to reduce the size of a program when running multiple parts in a production setup by using SUB-programs.

Brilliant video Tom ! Thank you

[@federicobarretto2627]

Excellent and simple explanation!!! 👏🏽

[@eugene1885]

Good vid.... Having it demonstrated was great as compared to deciphering it.... Needed a quick review to get a project finished... thanks!

[@forgamztalkzz8472]

Very clear, thank you.

That's such an amazing video

Thankyou Tom... :)

Just a quick question Tom, how to set a repeat on subprograms to cut to two or three parts the roughing if there is too big material to shaping off ?

[@janebibal7731]

Very useful .

Mr Stikkelman Thank you for your clear explanations on G programing. Could you explain us how to program a NPT thread in a milling machine by interpolation? I did oone time ago in it was a lot of calculations for a 1 inch NPT

Do you have to use multiple work offsets (not conducive to using a pallet system) and what if not all parts are oriented the same way to fit said pallet. My assumption is that you could use the same work offset so long as the cam compensates for the offset. I use one work offset for the pallet when camming parts affixed to pallet and use fusion 360 to assemple them prior to caming the ops.

I love it! I have a few questions... Where are the subprogram located? Are they different files, or different parts of the same file? If they are separate, how does program #1 identify them, and would they need to be in the same directory? Would other programs be able to call them as well? If they are part of the same file, how are they separated in the code? Thanks for all the work you put into these videos Tom, you are an excellent teacher.

[@TomStikkelman]

Good question. They are separate files in the program directory of the machine. The sub program is called using the M98 command. Yes. Other programs can also call these sub programs. Hope that helps.

I have an M98 P12345 L10 at the beginning of my program, after the safety codes but before it calls up the first tool to start machining. Program 12345 is a bar puller sub program I wrote and I want my program to run that sub then the main 10 times then stop. With the L on that line of code, it runs the sub only 10 times then it runs the main and then continuously loops nonstop. What am I doing wrong. I have an M99 at the bottom of both programs. Is the M98 in the wrong place? Is the L in the wrong place? I spent most of my day today trying to figure it out.

Email me your programs! [e-mail]

i don,t understand why you used G91 incremental mode before you send the tool to home position. thanks for efforts 👍✌

[@hatubadhan405]

How can i repeat subprogramm behind m98 put L?

Hi Tom; Rather than using g54, 55, 56.. I am getting a headache: N50 m97p300L10 N300 goxo.yo.z.1 N310 s1000 m03 n320 g1z-.2 F20. n330 y.75 n340 x2. n350 g91 x2.2 n360 m99 So, it isn't just moving over a set amount and running another pattern. I am trying to make a pile of smaller knockout parts from a length of flat... Hey, thank for posting! Mark

[@TomStikkelman]

+Mark Richardson Thanks Mark. M97 internal sub program call only works on a Haas.

[@markrichardson239]

What happens when I take it over to the Fadal for production? 2007 20x40 ? Ah... I might just stay on the Haas... What was the giveaway? M97 internal sub is Haas specific? ( I have a new control TM-2 ) Thanks yet again! Mark

sir how to learn about fanuc macro program

[@eddies6669]

Why did you pick a complex program?, you could have just used a line going back and forward, your trying to look smart by making things unpractical, the pont is to understand how to control only the subs, you get into all this extra bs to make it look "impressive",
