Fixed Cycles
Chapter 25
25-17
Function
This parameter is used for lathe controls only.
This parameter is used for the grooving cycles called by these G-codes:
G Code System Grooving in X Grooving in Z
A G75 G74
B G75 G74
C G76 G76
This parameter determines the retraction amount “e” for the grooving
cycles. Normally for these cycles, the control attains the programmed
depth of cut in steps. It infeeds a programmed amount and retracts an
amount “e.” This cut repeats until the control has reached the programmed
depth. Enter the distance of retraction “e” for the grooving cycles.
