AP Modes
AP modes I through V are explained here. You are advised to refer also to the "precautions" in
section 10-5-5.
10-1. AP Mode I (Bar Turning)
[Function]
In AP mode I, the area surrounded by the AP starting points and the contour defined by the contour
definition program starting with G81 (or G82) is cut while shifting the cutting level by the depth of cut
designated by D.
This mode is effective for normal turning, for example bar turning.
Since both rough turning and finish turning can be executed using the same contour definition
program when stock removal is designated using the U (X-axis direction) or W (Z-axis direction)
command, the program length can be reduced.
