Conversion Format
The radius vector and C-axis angle after coordinate conversion are calculated with the formula
below.

Program Examples
G137 is effective until G136 is designated. Do not designate other commands in the G136 block.
For the C command in a G137 block, designate the angle in reference to the C-axis zero point. This
angle is equivalent to "θ" in the figure in 2. "Conversion Format" above.
After designation of G137, use X and Y words instead of X and C words as positioning commands
until G136 is designated.
