Circular arc on lateral surface G112 / G113
The tool moves in a circular arc at the feed rate to the ”end point.”
Parameters
Z, C: End point, end angle
CY:
End point as linear value (referenced to unrolled reference
diameter G120)
R: Radius
K, W: Position, angle to midpoint
J:
Center point coordinate as a linear value (referenced to unrolled
G120 reference diameter)
X: End depth (diameter value) – default: current X-position
• Program either Z, C or Z and CY, or K, W or K and J.
• Program either center or radius.
• If you program a radius, the arc size cannot exceed 180°.
