Peck Drilling
I have to peck drill .128" for about 1/2" at the bottom of a 1/2" deep .136" hole. This is for a 1/8" rollpin. The larger hole provides a guide and makes it easier to assemble the pin and part.
With Haas' peck drill (G83?) and single step, you can't single step! It runs through the entire routine and I can't see the Z values. What I am trying to do is to rapid down to the bottom of the clearance hole and then start peck drilling, yet retract to clear chips to Z+.01. What it seems to do is feed for the first 1/2" cutting air. This is a four-up table load and I am trying to reduce the run time.
