Fundamentals
The control allows 3D tool compensation in CAM-generated NC programs with surface-normal vectors.
The control displaces the tool in the direction of the surface normals by the total of the delta values from tool management, tool call and compensation tables.
Tools for 3D tool compensation
Here are some examples of where 3D tool compensation can be used:
- Compensation for re-worked tools for compensating small differences between the programmed and the actual tool dimensions
- Compensation for substitute tools with deviating diameters for compensating even larger differences between the programmed and the actual tool dimensions
- Generating a constant workpiece oversize which may serve as a finishing allowance, for example
The situations below are some of the cases where 3D tool compensation can be used:
For an optional tool angle of inclination, the NC blocks must include an additional tool vector with the components TX, TY and TZ.
Note the differences between face milling and peripheral milling.
