Fig. 4-2: Circular interpolation with F8000 mm/min and Minimized Following-Error
Mode
In the circle shown in Fig. 4-2 the following-error is multiplied by an ex-
pansion factor of 1693.7. Here is the part program for the circle plot (Figs.
4-2 to 4-5).

The actual contour is nearly ideal on the NC control end due to the com-
pensated following error. A position deviation of 0.002 mm occurred only at
the transition between the squares. The position deviation at the transition
between the quadrants can be compensated for almost completely by pro-
gramming in addition friction compensation (see Chapter 11, "Special
Functions, AXD Command").
