    The document discusses various canned cycles used in CNC programming including G90 modal turning cycle, G71 rough turning cycle, G70 finishing cycle, G72 canned cycle facing, and G32 taper threading.

    The canned cycles discussed are G71 rough turning cycle, G70 finishing cycle, G72 canned cycle facing, and G32 taper threading.

    The parameters of the G72 canned cycle facing are: W - depth of cut, R - return value after a cut is complete, P - contour start block number, Q - contour end block number, U - finishing allowance in x-axis, W - finishing allowance in z-axis.
