When tool nose radius compensation is active, the control
automatically calculates the required equidistant tool paths to the
programmed contour for the current cutting radius R.
Equidistant
X
Z
The control requires the following information to calculate the tool
paths:
• The tool compensation data (length X, length Z, tool nose radius R,
tool point direction). The distance between the tool path and the
workpiece contour is calculated from the tool nose radius and the
tool point direction.
• The control recognizes the direction in which the tool path is to be
moved from the machining direction.
