SECTION 8 LATHE AUTO-PROGRAMMING FUNCTION (LAP)
(13) The steps described above are repeated until the X-axis reaches the level where a tool path is
generated below the "Xa + U" level. When this level is reached, the final rough turning is
carried out along the contour up to point B.
The feedrate for cutting along the final rough cutting contour is the one specified by the E word.

After the completion of the final rough turning step, the X- and Z-axes are relieved by 0.1 mm
(diameter value for the X-axis). The relief amount is set at Relieving amount in LAP-BAR
turning of optional parameter (OTHER FUNCTION 1).
(14) On completion of step (13), the axes return to the AP starting point (Xs, Zs).
There are two patterns of axis return motion:
The two axes return to the AP starting point simultaneously when G00 is designated in the first
block of the contour definition program (the block following the one containing either G81 or
G82).
When G01 is designated in the block indicated above, positioning on the X-axis is done first,
then the Z-axis returns to the AP starting point.
