SECTION 8 LATHE AUTO-PROGRAMMING FUNCTION (LAP)
[Supplement]
1) The blank material shape definition must always come before the blocks defining the finish
contour.
2) The blank material shape must be defined in the same direction as the finish contour is defined.
3) There are cases in which the NC changes the first element data of the blank material shape to
shorten cycle time. For example, in longitudinal cutting in the forward direction, if the X-
coordinate of the first element is smaller than the X-coordinate of the second element, the X-
coordinate of the second element is used as the X-coordinate of the first element.
