4.26 Lateral Surface Machining

Circular arc on lateral surface G112/G113

G112/G113 moves the tool in a circular arc at the feed rate to the “end

point.”

Parameters

Z End point

C End angle—for angle direction, see graphic support window

CY End point as linear value (referenced to unrolled reference

diameter G120)

R Radius

KCenter

W Center of angle (angular direction: see help graphic)

J Center point as linear value (referenced to unrolled G120

reference diameter)

X End point (diameter value)—(default: current X position)

Programming:

 Z, C, CY: Absolute, incremental, or modal

 K; W, J: Absolute or incremental

 Program either Z–C or Z–CY and K–J

 Program either center or radius

 For radius: Only arcs <= 180° are possible
