Study on Evaluation Index of Hard Machining Materials Based on the Application Feature

Abstract

For the same hard machining materials, the tool life, the axial distance for cutting and the material removal amount were adopted for the orthogonal test. The results show that the high tool life usually corresponds to low cutting parameters, which means the poor processing efficiency. The results have poor potential applications. The axial distance for cutting and the material removal amount can represent the machined surfaces and the removal quantity of materials, respectively, which can perfectly reflect the relation between cutting parameters and application effect. In the optimization test, the processing efficiencies by two evaluation parameters are all better than by tool life. But it's important to note that the results by two parameters are different, the special works still need to be made according to the real situation.
