6.21 Lateral Surface Machining
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)
