Pole definition, programming
G110 ; Pole specification relative to the setpoint position last programmed
(in the plane, e.g. with G17: X/Y)
G111 ; Pole specification relative to the zero of the current
workpiece coordinate system (in the plane, e.g. with G17: X/Y)
G112 ; Pole specification relative to the last valid pole; preserve plane
Information
S Pole definitions can also be performed using polar coordinates. This makes sense if a
pole already exists.
S If no pole is defined, the origin of the current workpiece coordinate system will act as the
pole.
Programming example
N10 G17 ; X/Y plane
N20 G111 X17 Y36 ; Pole coordinates in the current workpiece coordinate system
...
N80 G112 AP=45 RP=27.8 ; New pole, relative to the last pole as a polar coordinate
N90 ... AP=12.5 RP=47.679 ; Polar coordinate
Traversing with polar coordinates
The positions programmed using polar coordinates can also be traversed as positions speci-
fied with Cartesian coordinates as follows:
S G0 – linear interpolation with rapid traverse
S G1 – linear interpolation with feedrate
S G2 – circular interpolation CW
S G3 – circular interpolation CCW
(see also Section 8.3 “Axis movements”).
8.2.5 Programmable work offset: TRANS, ATRANS
Functionality
The programmable work offset can be used for recurring forms/arrangements in various positions on a
workpiece
or simply for the selection of a new reference point for the dimensional information
or as an allowance for roughing. This results in the current workpiece coordinate system.
The newly written dimension specifications are referred to this coordinate system.
The offset is possible in all axes.
