The circularity (roundness) test
20.3.1 Interface description
The screen of the circularity test looks like this, with two clearly different parts. A graphics
window that shows the result of the test and a data area for interacting with the system.
The graphics window
It is the area that shows, graphically, the result of the test. The graphic shows the two moving
axes and the theoretical circle of the interpolation that will be carried out. As the test is being
run, the positioning error at each point is drawn on the circle. This error is shown projected
radially.
Superimposed on the graphics, it shows the following additional data that is updated by the
CNC.
• The real coordinates of the axes.
• Programmed feedrate and % applied.
• Diameter of the displayed circle.
• Maximum and minimum error over the theoretical radius and angular position where it
has been detected.
The data area
It is the area where the user interacts with the system. It offers a set of data for defining the
graphic environment, the subroutine that will be used to generate the machine movement
and the machine parameters involved in the adjustment. Selecting one of the data frames
the group of parameters it belongs to.
Graphic environment data to be configured
• Number of divisions on both sides of the theoretical circle.
• Scale or value in microns of each division.
• Error margin. Percentage of the area that is occupied by the error margin (divisions area).
