X0, Y0 : Center of the ellipse Process: The points of the ellipse are calculated and connected by many short lines. The more points that are calculated and the shorter the lines between them, the smoother the curve. The machining direction can be varied by changing the entries for start and end angles. The input parameters are listed below in blocks 112. Calculations are programmed with the FORMULA function. a, b Y Y b Y1 X2 a Y2 b 2 1 X1 a P X Y Y Q5 S X DR 0 = E Q4 DR+ X X Part program 0 BEGIN PGM K72 MM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
