Need help setting up a custom drill cycle for thru spindle coolant drills in a VMC. I will be spotting the holes 2xD with short drill first. After the holes are spotted this is what I am looking to do:
Enter hole at a lower rpm (around 300rpm)
Turn TSC ON
Ramp spindle speed to desired RPM
Drill Hole
Return to origanal starting point
Ramp RPM back down
Turn TSC OFF
go to next hole
Custom drill cycle seem like the way to go to do this just not familar with them and the daocumentation is lacking to say the least. We drill anywhere from 100 to over a thousand holes in one block. I have been able to use normal drill cycles for the shorter drill but when using 15D or 20 D drills they will snap if the tip is not supported in the hole when ramping up to proper spindle RPM. I might want to try a different variation where the TSC coolant stays on the entire time instead of on/off for every hole. I will say that I do not program everyday but trying to utilize the machine and tooling to their potential. Thank you for any help.
