Circular arc, lateral surface G112/G113
Geometry command: G112/G113 defines a circular arc in a contour
on the lateral surface.
Machining command: The tool moves on a circular arc at feed rate to
the end point.
The direction of rotation is shown in the graphic support window.
Parameters
 Z end point (default: Current Z position)
 C end angle —for angle direction, see graphic support window
 CY end point as linear value (reference: G120 reference diameter)
 R radius
 K center point
 J center point as a linear value (reference: unrolled G120 reference
diameter)
 W center point: Angle to center—for angle direction, see graphic
support window
 Q point of intersection (default: Q=0): If entered data permit two
possible solutions for the end point, "Q" defines the end point.
 B chamfer/rounding arc: Transition to the next contour element
When entering a chamfer/rounding, program the theoretical end
point of the contour element.
„ B no input: Tangential transition
„ B=0: No tangential transition
„ B>0: Radius of rounding
„ B<0: Width of chamfer
 X end point: infeed (diameter value)—(default: Current X position)
