(1) Figure data of the start point
START POINT Y : Y coordinate of the start point (radius)
START POINT Z : Z coordinate of the start point (radius)
START PNT C COORD. C : Angular displacement of the workpiece
(C coordinate)
BOTTOM X : X coordinate of the bottom of the cut
NOTE
1 The cutting start point is determined from the X coordinate
of the bottom of the cut and the depth of cut. If the depth
of cut is not large enough to enable positioning of the cutting
start point outside the blank, the tool may collide with the
blank during rapid traverse.
(2) Selecting a contour and entering the figure data
After entering the figure data of the start point, press the [INSERT]
soft key. The following soft key menu for selecting a contour is
displayed:
