4.2.1 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.
Programming
G110 X… Y… Z…
Pole parameter, with reference to the last approached position in
Cartesian coordinates
Or
G110 AP=… RP=…
Pole parameter, with reference to the last approached pole in
polar coordinates
Or
G111 X… Y… Z…
Pole parameter, absolute in workpiece coordinate system with
Cartesian coordinates
Or
G111 AP=… RP=…
Pole parameter, absolute in workpiece coordinate system with
polar coordinates
Or
G112 X… Y… Z…
Pole parameter, with reference to the last valid pole with
Cartesian coordinates
Or
G112 AP=… RP=…
Pole parameter, with reference to the last valid pole with polar
coordinates
