Peck drill cycle problem.

[odessa]

Good Morning.

I need to change something in my lathe postprocessor to get right drill cycle in a program but I do not know what. Please look to my pics.

Thanks.

Not in the right forum. This is for scripting code not posts. 

Someone please move.

this is not a post problem. You have set our value to incremental .1 and if you are at -.9 on the depth then you will get the output you are getting. Change to absolute .1 and you will get the correct output. 

Welcome to the Mastercam forum.

I have it in absolute.

The post is outputting the correct value for a Fanuc style control.

R is treated as an incremental value from the INITIAL plane, So, an Absolute Z.1 IS -.9 from an initial plane of Z1.0 as in your program.

The absolute/incremental in the cycle only determines where the R plane should be in reference to the geometry. It has no bearing of whether or not an R value is absolute or incremental in the control. Those are two different things.

From a Fanuc manual:

Now, if you want this to do something else, it will probably be in the prdrlout or lchpbrk$ postblock.

But since I'm not too well versed in the LATHE POST BY LEO postprocessor, I can't tell for sure.
