Single-Pass Turning Cycles
Chapter 22
22-8
G24 calls either a straight or a tapered facing cycle. This cycle is a
single-pass cycle (makes only one cutting pass over the workpiece each
time it is called).
Use the G24 cycle to cut along the face of a workpiece (in this manual that
means it cuts along the X axis). The G24 cycle basically consists of the
moves shown in Figure 22.6.

CAUTION: When programming the single-pass cycle, the first
move to the depth of cut is a rapid move. Make sure that the
tool does not contact the part on this initial move.
