G24 calls either a straight or a tapered facing cycle. This cycle is a single
pass cycle (makes only one grinding pass over the workpiece or one
dressing pass over the wheel each time it is called).
Use the G24 cycle to grind along the face of a workpiece (in this manual
that means it grinds along the X-axis). The G24 cycle consists of the
moves shown in Figure 18.6.

1 -- Rapid approach to the part
2 -- Grinding/Dressing feed into the part
3 -- Grinding/Dressing feed out of the part
4 -- Rapid return to the start point
ATTENTION: When programming the single pass cycle, the
first move to the grinding/dressing depth is a rapid move. Make
sure that the grinding wheel does not contact the part on this
initial move.
The single pass cycle uses the currently active programmed
grinding/dressing feedrate. You can specify a different grinding/dressing
feedrate in the single pass cycle block.
Use the rapid feedrate (for the axis in motion as assigned in AMP) for the
approach to the part and the return to start point.
