ABSTRACT:
The coordinates (X.sub.n+1 Y.sub.n+1) of an arc to be traced at time t.sub.n+1 are preliminary calculated using the coordinates (X.sub.n Y.sub.n) at time t.sub.n, the radius (r) of the arc and a specified length l.sub.n during the time t.sub.n+1 -t.sub.n, thus the number of the calculations required for tracing an arc is considerably reduced and a low speed digital element which is cheap can be utilized in the present arc interpolation system. The formula for obtaining the coordinates is;
