Defining the pole (G110, G111, G112)

Function
The dimensioning starting point is called a pole. The pole can be specified in either
Cartesian or polar coordinates (polar radius RP=... and polar angle AP=...). The
programming commands G110 to G112 are used to provide a unique definition of the
reference point for dimensions. Therefore, neither absolute nor incremental dimensioning
affects the system defined in the programming command.
