This paper describes a generalized method of cutter-direction control using DDA (Digital Differential Analyzer) algorithms. The method is applicable to cutting out two dimensional arbitrary shapes with high accuracy. The cutter path generation process requires a method for moving the cutter along the lines of the figure and for keeping the cutter tip tangent to lines of the figure. The algorithm is capable of generating equations for lines, arcs, ellipses, and arbitrary shapes. For complex shapes, the DDA algorithm generates the desired functions which represent the lines of figure and the tangent lines are generated from points input by a user. From this information, the motor control parameters for cutting these shapes may be easily obtained.
