Circular Interpolation Test - HEIDENHAIN iTNC 530 HSCI Service Manual

10.5.2 Circular interpolation test

The integrated oscilloscope of iTNC 530 HSC also features a circular interpolation test.
With this test, for example the static and sliding friction at the quadrant transitions can be analyzed.
Example of a circular interpolation test with the integrated oscilloscope:

Note
The integrated circular interpolation test with the mounted encoders (e.g., linear encoders) does
not serve to test the geometry of the machine.
Additional measuring equipment (e.g., KGM grid encoder from HEIDENHAIN) is required for this
purpose.
Choose the CIRC operating mode in the oscilloscope.
Set Contour deviat. twice.
Select the axes involved (XY, YZ, XZ).
Note
If required, ask the machine operator how to operate the machine and how to create and execute
the NC program!
Position the axes in an area that allows safe traverse of the circle.
Set the reference points for X and Y as follows:
Write a simple NC program, such as:
10 – 109
