Notes:
Approximate Double Circular Arc Interpolated Method (ADCAIM) has been proposedby the authors. It requires only the included angles in the normal directions of the adjacent arcs atintersection points to be less than specified value, but does not require the adjacent arcs to betangent as in other circular arc interpolated methods. ADCAIM is an approximate method withbetter calculating speed because of its concise calculation, and its interpolated error can meet therequirement too. The problems in NC programming of aspheric curves have been solved by usingADCAIM. In this paper, to the plane profile including aspheric curves, using VB program languageas the second development tool, auto-programming for NC machining of aspheric curve is alsorealized by using ADCAIM, as long as the curve’s profile graphics on the AutoCAD is known. Theresearch result indicates: the method introduced in this paper can meet the needs of NC machiningin both interpolated accuracy and calculating speed for the example
