13.3 The circularity (roundness) test
This tool helps improve and adjust the axis reversal peak, an effect that appears when
the axes reverse their moving direction. With this utility, a circle may be executed with
the axes and graphically show the result. This graphic shows the difference between
the actual (real) coordinate obtained from the feedback device and the theoretical
coordinate calculated at each point. This difference is shown projected radially.
The same screen showing the graphics also shows the machine parameters that
affect the movement reversal. These parameters may be modified while running the
test, thus being possible to evaluate the response of the system to these changes
and optimize the adjustment on the go.
The circularity (roundness) test diagram is an assistance tool that only shows the
response of the system to the various settings (adjustments); it is up to the technician
to choose the best adjustment.
How to access the circularity (roundness) test
The circularity (roundness) test may be accessed from the softkey menu for setup
assistance.
