SECTION 8 LATHE AUTO-PROGRAMMING FUNCTION (LAP)
(1) AP Mode I, Longitudinal Cutting Mode (G85 + G81 + G80)
LE33013R0301000030011
Cutting is executed while shifting the cutting level by the depth of cut. A part program can be
created by simply designating the finish contour data.
(2) AP Mode II, Longitudinal Cutting Mode (G86 + G81 + G80)
LE33013R0301000030012
Cutting is executed along the finish contour. Cast-iron and forged workpieces can be cut at a
higher speed than in AP Mode I since unnecessary tool motion is reduced.
(3) AP Mode III, Longitudinal Cutting Mode (G88 + G81 + G80)
LE33013R0301000030013
