Code for the 8L

[Jace_Snider]

So I run a Harrison lathe at work and just write my own programs instead of using conversational. However I started writing one on the 8L and was running into a problem with G71 canned cycle. Can some one help me with this so it’ll accept my programs and can someone send a reference on how to g code program the 8L?

Thanks!

Does your control at work use a single or double line G71/72?

G-code descriptions

I was looking for a G71 breakdown. I found one, but not PathPilot so the variables were incorrect. On Tormach’s site there is a g-code list but G71 is not on it. G71 P1294 D0.0200 F0.0050 J0.0060 L6 I0.0030 K0.0030 R0.0200 E0 Can anyone define this. P not sure. D is depth of cuts F is feed rate J, I and K unknow - if there were only 2 I would think that is stock to leave on X and Z L is the number of times to repeat the cut. R is the retract amount E is anyone’s guess. I don’t mind ma…

This post may have what you need in it.

It’s a double line so for example:

G71 U.01 R.1
G71 P101 Q102 U.005 W.005 F.010

P is the sub routine address line so for the profile of the part

You could use About Tormach Virtual PathPilot to spin up an instance and simulate it.
