Single-Pass Turning Cycles
Chapter 22
22-9
The feedrate used in the single-pass cycle is the currently active
programmed cutting feedrate. If desired, a different cutting feedrate may
be specified in the single-pass cycle block.
The rapid feedrate (for the axis in motion as assigned in AMP) is used for
the approach to the part and the return to start point.
G24 Straight Facing
The format for the G24 straight facing cycle is:
G24X__ Z__;
Where : Is :
X__ the length of cut 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 cutting stroke. X may be programmed as either a diameter or radius value.
Z__ the depth of cut for the Z axis. In incremental mode, specify the amount of infeed. In
absolute mode, specify the coordinate position at the desired depth of cut.
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.
