of cut.

Example: G76 X60640 Z25000 K3680 D1800 F6.0 A60 P2;

For staggered thread cutting, always use the FS15 tape format (see

Section 17.5).

When command P instructing a cutting method is not specified or a

command other than P2 is specified, one–tool cutting is performed by a

constant amount.

If the depth of cut in one cycle is less than dmin (specified in parameter

No. 5140), the depth of cut is clamped at ∆dmin.
