With the straight line function LP you program a straight traverse motion in any direction using polar coordinates.
Application
Requirement
- Pole CC
You must define a pole CC before programming with polar coordinates.
Description of function

The control moves the tool in a straight line from its current position to the defined end point. The starting point is the end point of the preceding NC block.
You define the straight line with the polar coordinate radius PR and the polar coordinate angle PA. The polar coordinate radius PR is the distance from the end point to the pole.
- The algebraic sign of PA depends on the angle reference axis:
- If the angle from the angle reference axis to PR is counterclockwise: PA>0
- If the angle from the angle reference axis to PR is clockwise: PA<0
