Rotating Sensitive Radial
Rotating Sensitive Radial acquires distance data from two probes positioned 90° apart. The probes measure the X and Y displacement of the axis of rotation to generate a polar plot using the Tlusty or B89.3.4 method. This test is valid for processes such as milling, boring, and drilling, where the tool is rotating in the spindle.
Rotating Sensitive Radial measures changes in the position of the axis of rotation in two directions and evaluates the following aspects of machine tool performance:
