Fixed Sensitive Radial
Fixed Sensitive Radial acquires displacement in the X direction relative to angular position of the axis of rotation and displays the data in a polar plot.
This test is valid for processes such as turning and some grinding processes where the part is rotating in the spindle, or where the point of contact between the grinding wheel and part are at a fixed position such as surface grinding.
It measures changes in the axis of rotation in one direction and evaluates the following aspects of machine tool performance:
