SECTION 8 LATHE AUTO-PROGRAMMING FUNCTION (LAP)
(6) After point B is reached, the final contour of the rough turning cycle is cut up to the point whose
X coordinate is Xb + D. If G80, indicating the end of contour definition, is found before this point
is reached, the final rough turning contour is cut up to the point specified in the block preceding
the G80 block.
The feedrate in this cut is as specified by E which is designated in a contour definition program.
If no E word is provided in the corresponding contour definition program, the one specified last
is effective. When an E word has not been specified, the feedrate specified when the rough
turning cycle was called out is effective.

(7) After the completion of cutting explained in (6), the cutting tool is relieved from the workpiece in
the direction opposite to the infeed direction along the X-axis and opposite to the cutting feed
direction along the Z-axis, by 0.1 mm (0.004 in.) on each axis (diameter value in the case of the
X-axis).
The relief amount is set for the optional parameter (OTHER FUNCTION 1) in units of µ.
