leblond makino drilling cycle

[OTOMMYO]

Im drilling a hole z-16. deep but want my drill to start at z-8. and still retract to z.25 to clear the chip. Is their a way to do this w/o cutting air for the first 8"?

 

This is what I have now...

I set up a macro for secondary (long drill) on a few of our VMCs, but I've never set it up in MC.

 

code:

---

:8800(SECONDARY PECK)

(Z=#26 - DEPTH)

(R=#18 - RAPID HEIGHT)

(Q=#17 - PECK AMT)

(F=#9 - FEED RATE)

(I=#4 - INITIAL TOOL DEPTH)

(J=#5 - JUMP HEIGHT)

(K=#6 - PECK CLEARANCE)

(C=#3 - CHIP REMOVAL PLANE)

#1=#4-#17
