| Abstract: | To realize multi axis machining for parts of complicated shapes with high precision and high efficiency, one important way is to enhance data processing ability of CNC system, i.e., the ability to interpolate arbitrary curves. A mathematical model and 5 axis programming pattern for arbitrary parabola is developed, and an iterated interpolation method for arbitrary parabola and interpolation methods for rotating coordinates and linear coordinates is suggested. Interpolation error estimation formulas for speed error, arc height error and rotating coordinate error are derived. Theoretical analysis and case study show that the method proposed is of low speed error and locus error. |
