Abstract
The purpose of the paper is to improve the efficiency of mechanical processing of parts from hard-to-machine materials by using special designs of face mills with variable cutting patterns. The study uses experimental and theoretical research methods of improving the performance of required designs of face mills with disposable hard alloy inserts for the processing of hard-to-machine materials at their design stage. The method of designing special constructions of face mills with disposable hard alloy inserts for milling of hard-to-machine materials for both rough and finishing machining has been developed. The use of computational methods allows to eliminate the influence of subjective factors on design quality and reduces design complexity. The use of special face mills with disposable hard alloy inserts operating with reverse shavings increases the efficiency of both rough and finishing machining of parts from hard-to-machine materials and from 2 to 10 times intensifies metal removal as it was proved by the results of laboratory and production testing. In some cases they are the only possible machining option in production conditions.
