G71 turning cycle is used for rough-material removal from a cnc lathe component. G71 turning cycle makes large diameter cutting easy. Cutting can be done in simple straight line or a complex contour can also be machined very easily.
Through G71 turning cycle parameters cnc machinists can control
Depth of cut.
Retract height.
Finishing allowance in x-axis and z-axis.
Cycle cutting-feed, spindle speed.
ParameterDescription
U=Depth of cut.
R=Retract height.
Second block
ParameterDescription
P=Contour start block number.
Q=Contour end block number.
U=Finishing allowance in x-axis.
W=Finishing allowance in z-axis.
F=Feedrate during G71 cycle.
S=Spindle speed during G71 cycle.
