This paper describes new methods to minimize the cutting time in zigzag milling operation of two dimensional polygonal surfaces. Previous works have been focused mainly on experimental approaches by considering some machining parameters such as, spindle speed, depth of cut, cutter traverse rate, cutter diameter, number of teeth, and so on. However, in this study, we considered a geometrical factor, which is the length of cut. In an N-sided concave or convex polygon, an algorithm has been developed which minimize the total length of cut.
