Is it possible to edit a canned cycle? I'm working on an old 16i-M control and the G83 pecking cycle is horrible. Every peck starts .1" above the previous depth. This is consuming large amounts of time when I'm trying to do .050" pecks in a 1.5" deep hole. If I could change it to start .005" above the previous level, that would make this cycle nearly 3x faster. I'm aware that I could write my own macro - but that's not really a solution. I want this fixed at the machine, not the post, if it's possible.

Cavi,

Look in your parameter manual. There are a couple of parameters that can fix this problem.

Check parameter 5174
(I am not very sure because I do have the manual in front of me)

The unit is 0.0001 inch in inch mode, in IS-B.
So, a value of 100 means 100 x 0.0001 inch = 0.01 inch

I believe you're looking for parameter 5114 and 5115. But, as Chris D suggested, look in your parameter manual for a more detailed description.

That is how a typical G83 cycle works . If you need a every cut to start above 0.005" then you have to use a different cycle like G73

5114 for for G73, and 5115 for G83
G73 for partial retraction, and G83 for full retraction.
G83 is used when chip removal is difficult (e.g., in a small diameter hole, with a large L/D ratio)
G83, however, is not too slow, because the inward motion up to the defined clearance (5115) is at the rapid rate; feed motion starts after that.

If you have access to operator's manual and parameter manual, you can have such information in a minute.
