We just got our Hardinge GX1000 with an Okuma OSP-P200 control up and running the other day and I've done a couple jobs already without a problem. Today I was drilling some holes in the bottom a of a c'bore and I came across a problem. My Z zero was the top of the part and my Z starting point is Z-1.000 and then I drill a hole 7/8 deep. I use GibbsCam to program, all my other machines will output a G98 or G99 when I'm below the the Z zero plane. What does the Okuma use in this situation? I looked in the manual but didn't find much info on this, it was towards the end of the day so I didn't have much time. Does Okuma use a different G-code for this type of application? I did see something about a G71 but didn't have enough time to read up on it. One more question, I was using a G73 drill peck cycle and I was wondering if there was a parameter setting somewhere to tell the machine to stop a specific distance when the tool rapids back down into the hole? I broke a couple small drills today and was wondering if the tool was stopping on the rapid before it hit the bottom of the hole.
