2.18.2 Radial Cutting Cycle G94
Command function: From start point, the cutting cycle of cylindrical surface or taper surface is
completed by radial feeding(X) and axial (Z or X and Z) cutting.
Command format(A set) : G94 X(U) __ Z(W) __ F__; (face cutting)
G94 X(U) __ Z(W) __ R__ F__; (taper face cutting)
Command format(B set) : G79 X__ Z__ F__

Code specifications: G94/G79 is modal;
Cycle process:
①
Z rapidly traverses from start point A to cutting start point B;
②
Execute linear interpolation from the cutting start point B to cutting end point C;
③ Z executes the tool retraction at the cutting feedrate (opposite direction to the
above-mentioned
①
), and returns to the position which the absolute coordinates and the
start point D are the same;
X_,Z_ Coordinate of cutting end point(C point in the figure below)in the direction of
the bottom side
U_,W_ Movement to cutting end point (C point in the figure below)in the direction of
bottom side
F_ Cutting feedrate
