The Study of the Programming Error Effected by Argument on NC Machining

This paper researches the effects of argument for programming errors based on ellipse CNC variable programming, analyzes programming error characteristics of the arguments θ, X, y, finds visible difference on programming error distribution and maximum value, Then presents the means on variable programming by a selection of the appropriate argument, and uses the multiple arguments for segmented programming to reduce programming error, Finally, gives an example to show the effectiveness of the method.
