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.

4 -- Rapid returntothe startpoint

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.
