Fig3.13.1 Example of Polar Coordinate
(a) Specifying angles and a radius with absolute commands.
N1 G17 G90 G16 X0 Y0;
Specifying the polar coordinate command and selecting the XY-plane setting the zero point of
the workpiece Coordinate system as the origin of the polar Coordinate system.
N2 G81 X100.0 Y30.0 Z-20.0 R-5.0 F200.0;
Specifying a distance of 100mm and an angle of 30 degrees
N3 Y150.0;
Specifying a distance of 100mm and an angle of 150 degrees
N4 Y270.0;
Specifying a distance of 100mm and an angle of 270 degrees
N5 G15 G80;
Canceling the polar Coordinate command & drilling cycle.
(b) Specifying angles with incremental commands and a radius with absolute commands
N1 G17 G90 G16;
Specifying the polar coordinate command and selecting the XY plane. Setting the zero point of
the workpiece Coordinate system as the origin of the polar Coordinate system.
N2 G81 X100.0 Y30.0 Z-20.0 R-5.0 F200.0
Specifying a distance of 100mm and an angle of 30 degrees
N3 G91 Y120.0;
Specifying a distance of 100mm and an angle of +120 degrees
N4 Y120.0;
Specifying a distance of 100mm and an angle of +120 degrees
N5 G15 G80;
Canceling the polar coordinate command.
(c) Specifying a radius in the polar Coordinate mode
In the polar Coordinate mode, specify a radius for circular interpolation or helical cutting (G02,
G03) with R.
Neither optional-angle chamfering nor corner rounding can be commanded in polar Coordinate
mode.
-
The zero point of the work
coordinate system is set as the
origin of the polar Coordinate
system.
- The XY plane is selected.
