This cycle allows cutting a fixed pattern repeatedly, with a pattern being displaced bit by bit.
Format : G73 U(i) W(k) R(d)
G73 P__ Q__ U(u) W(w) F__
Where ,
U(i) = Distance of relief in X direction
This U(i) = (Job. Diameter –
Min. Diameter in the program) / 2
W(k) = Distance of
relief in Z direction
R(d) = No. of divisions
for the pattern.
This R = ( U(i) / Max. Depth
of Cut) + 1
P = Starting block no. of the program for the
required shape
Q =
Final block no. of the program for the
required shape
U(u) = Finishing allowance in X direction.
W(w) = Finishing allowance in Z direction.
F =
Feed-rate for cutting.
