G24 Tapered Facing
A G24 block that includes a K word generates a facing pass that produces a
taper.

The format for the G24 single pass cycle to grind a taper on a face is:
G24X__Z__K__;
Where : Is :
X__ the length of grind along the X-axis. In incremental mode specify the amount of
feed across the part, in absolute mode specify the coordinate position of the end
point of the grinding/dressing stroke. X can be programmed as either a diameter
or radius value.
Z__ the grinding/dressing depth for the Z-axis at the end point of the
grinding/dressing move into the part. In incremental mode specify the amount of
infeed, in absolute mode specify the coordinate position at the desired
grinding/dressing depth.
K__ the amount of change in the grinding/dressing depth for the Z-axis. K is always
an incremental value. Figure 18.9 shows the relationship between the sign of the
K value and the way that the cycle is performed. The control adds the value of
K to the Z depth to determine the start point of the grinding/dressing pass.
