It is also possible to use polar programming when the angles are

programmed in absolute mode and the radii are in incremental. See

Example 14.11 and Figure 14.15.

Polar Pr ogramming - Angle in Absolute, Radii in Incremental

N10 G00 X0Y0 F500; rapid move to X0 Y0

N20 G90 G81 X3.Y0 R3. Z10.; drilling cycle at X3 Y0

N30 G16; polar programming

N40 G91 X4. G90 Y135.; radius of 4 at 135 deg abs

N50 Y225.; still radius of 4 at 225 deg abs

N60 Y315.; still radius of 4 at 315 deg abs

N70 G15 X6. Y0 cancel polar, move to X6 Y0

N80 G16; polar programming

N90 G91 X8. G90 Y135.; radius of 8 at 135 deg abs.
