The highly effective processing is the stone cutting tool processes the greatest quantity by the lowest cost or removes most materials, the lowest cost must depend on the exten the life of stone cutting tool to guarantee. Enhances the stone cutting specifications (cutting velocity, feed rate, back of cutting) to enhance the processing efficiency effectively, but, if the stone cutting specifications are excessively higher, the stone cutting tool will be worn seriously, service life of stone cutting tool will also reduce and the processing cost is corresponding to rise. Therefore, there is a reasonable technological parameter between the processing efficiency and the stone cutting tool abrasion which can cause the stone cutting tool obtains the highest processing efficiency in the normal wear situation.
