7.5.8 Circle geometry test
This adjustment improves the axis reversal peaks. It consists in machining a circle (without
compensation) and verifying it on the graph displayed at the CNC.
The following example shows a program that machines repetitive circles.
After selecting this program in the Execution mode and starting it, access the "Diagnosis,
Adjustments, Circle Geometry test" mode and the CNC will display the following screen:
If the machine parameters are protected, it will request the access password because the bottom
right of the screen shows some of them. When not knowing the password, those values cannot be
changed, but it will be possible to access the screen and the circle geometry test.
The left side of the CNC screen shows the result of the test.
The data at the top right is refreshed by the CNC after the test is completed.
The data at the center right must be defined before running the test.
The bottom right side of the screen shows the parameters associated with the plane axes and the
values to set them.
The graph on the left must be defined before running the test. To do that, define the data of the center
right:
• Number of divisions to the left and to the right of the theoretical circle.
• Scale or value in microns of each division.
• Error margin or % of circle radius occupied by the error margin (divisions area).
Knowing the password, the values shown at the bottom right may be modified. The CNC assigns
the new values to the relevant machine parameters; therefore, it is recommended to jot the initial
values down.
Once the graphic display area and the machine parameters have been defined, capture the data
by pressing the following softkeys:
SIMPLE
It deletes the current graph and draws, over the theoretical circle, the machining error enlarged
according to the defined scale until a full circle is drawn or until the STOP softkey or ESC key is
pressed.
