Single-Pass Turning Cycles
Chapter 22
22-12
After the G24 block is executed the control re-executes the cycle for any
following block that commands axis motion (until the cycle is cancelled).
The value of the axis word in that block is used to replace the parameter
determined with that axis word in the original G24 block and the cycle is
re-executed using these new parameters.
Figure 22.9 applies only if programming X and Z as incremental values. If
programming X and Z as absolute values, the depth of taper K is added or
subtracted (depending on its sign) to the absolute Z axis position.
