Longitudinal contour roughing G817/G818
The cycles machine the contour area described by the current tool
position and the data defined in the subsequent blocks in longitudinal
direction without recessing (see “Contour definition” on page 310).
Parameters G817, G818
 X cutting limit (diameter value): The control machines up to the
cutting limit.
 P maximum infeed: The proportioning of cuts is calculated so that an
"abrasive cut" is avoided and the infeed distance is <= P.
 H type of departure (default: 1):
„ 0: Machine contour outline after each pass
„ 1: Retract at 45°; machine contour outline after last pass
„ 2: Retract at 45°; do not machine contour outline
 I oversize X (diameter value)—(default: 0)
 K oversize Z (default: 0)
