Y Axis 10
Full circle G374 Geo
G374 defines the contour of a full circle in the XY plane.
Parameters
X, Y: Circle center (X radius dimension)
R: Circle radius
P: Depth/height and position of the milling contour – no entry:
”P” from G308
■ P<0: Pocket
■ P>0: Island
I: Area diameter (as cutting limit)
■ No entry: ”X” from the section code.
■ ”I” overwrites ”X” from section code.

R: Curvature radius (reference: center point path of the slot)
B: Slot width
A, W: Starting angle, ending angle (reference: positive X axis) –
default: 0°
P: Depth/height and position of the milling contour – no entry:
”P” from G308
■ P<0: Pocket
