What additional item is needed to create a contour with Tool Radius Compensation?

To create a contour with Tool Radius Compensation, it's essential to accurately account for the axis orientation of the tool. This is because Tool Radius Compensation adjusts the programmed path of the tool based on its radius, ensuring that the cutting edge follows the intended contour rather than the center of the tool.

The orientation of the tool directly influences how the radius compensation is applied, especially during circular arcs or curved paths. If the tool’s orientation is not correctly defined, the compensation may lead to an inaccurate cut, as the machine may not adjust the tool path effectively according to the geometry of the workpiece.

Understanding and setting the correct axis orientation before applying Tool Radius Compensation ensures that the CNC machine can accurately follow the programmed contour while maintaining the desired dimensions and surface finishes of the part.
