Considering the cost of processing efficiency and

Selected cutting should meet the required criteria and optimization of cutting tools required reliability. Now, the most widely used process cost optimization criteria are guidelines, in addition, there is the principle of the shortest processing time and so on. In the author  cutting tools the optimization is to choose the smallest craft cost principle, this principle into account the processing efficiency and  abrasive grinding costs. According to this principle, choose a higher cutting speed and relatively low tool life is reasonable. In order to ensure stability of CNC machine tools and machining centers work and does not produce waste, it must ensure that the tool has a high operational reliability.
