Polygonal turning means machining a polygonal figure by rotating the
workpiece and tool at a certain ratio.

Workpiece
By changing conditions which are rotation ratio of workpiece and tool and
number of cutters,the machining figure can be changed to a square or
hexagon. The Machining time can be reduced as compared with
polygonal figure machining using C and X axes of the polar coordinate.
The machined figure however, is not exactly polygonal. Generally,
polygonal turning is used for the heads of square and/or hexagon bolts or
hexagon nuts.

G51.2(G251) P_Q_;
P, Q
: Rotation ratio of spindle and Y axis
Specify range:Intefer 1 to 9 for both
P and Q
When Q is a positive value, Y axis
makes positive rotation.
When Q is a negative value, Y axis
makes negative rotation.
