Along with increasingly development of CAD/CAM software and their application in various industries, minimizing of the machining time is found to bemore important. In this paper, firstly the concerning subjects are discussed regarding classification of the optimization techniques. These are programmingtechniques, high speed machining techniques and feed rate optimization techniques. As a case study, an NC code was generated for machining of a plasticdie by means of a dedicated software and the die was machined conventionally. Then the workpiece was machined using optimization techniques. Finally times taken for two approaches have been compared. The result shows machining time after optimization has been reduced considerably (64%).
