Circular path C

Application

You use the circular path function C to program a circular path around a circle center point.

Requirement

Description of function

The control moves the tool on a circular path from the current position to the defined end point. The starting point is the end point of the preceding NC block. You can use at most two axes to define the new end point.

If you want to program a full circle, then define the same coordinates for the starting and end point. These points must lie on the circular path.

 
Tip

In the machine parameter circleDeviation (no. 200901) you can define the permissible deviation of the circle radius. The maximum permissible deviation is 0.016 mm.

With the direction of rotation you define whether the control moves along the circular path in a clockwise or counterclockwise direction.

Definition of the direction of rotation:

  • Clockwise: direction of rotation DR– (with radius compensation RL)
  • Counterclockwise: direction of rotation DR+ (with radius compensation RL)
