Polar coordinates
If a workpiece has been dimensioned from a central point (pole) with radius and angles, you
will find it helpful to program these dimensions as polar coordinates.
Before you program a straight line or circle in polar coordinates, you must define the pole,
i.e. the reference point, of the polar coordinate system.
Procedure
1.
The ShopTurn program to be processed has been created and you are
in the editor.
2.
Press the menu forward key and the "Straight Circle" softkey.
3.
Press the "Polar" and "Pole" softkeys.
