section
Cycle end / Simple contour G80
By programming G80 (with parameters), a turning contour
consisting of more than one element can be defined in one NC
block. G80 (without parameters) ends a contour definition directly
after a cycle.
Parameters:
XS: Start point of contour in X (diameter value)
ZS: Start point of contour in Z
XE: Final point of contour in X (diameter value)
ZE: Final point of contour in Z
AC: Angle of first element (range: 0° <= AC < 90°)
WC: Angle of second element (range: 0° <= WC < 90°)
BS: -Chamfer/+radius at start
WS: Angle for chamfer
BE: -Chamfer/+radius at end
WE: Angle for chamfer at contour end
RC: Radius
IC: Chamfer width
KC: Chamfer width
JC: Execution
0: Simple contour
1: Expanded contour
EC: Type of contour
0: Rising contour
1: Plunging contour
HC: 1: Transverse – contour direction for finishing
0: Longitudinal
1: Transverse
IC and KC are used in the control to show the chamfer/rounding
cycles.
