Circular path C
Application
You use the circular path function C to program a circular path around a circle center point.
Related topics
- Programming a circular path with polar coordinates
Requirement
- Circle center point CC is defined
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.
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)
Input
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
