Study of the Cutting Regimes in a Class of Machine Tools Aiming at Their Improvement

The main factors influencing the cutting regimes in a type of turning machines with computer numerical control (CNC) are summarized and analyzed. On this basis, some approaches for their optimization are presented and discussed. The aim of this research is to find appropriate combinations of the cutting parameters such as cutting speed, feed speed, cutting depth, nose radius, rake angle and the respective tools that lead to minimal energy consumption and maximum material removal rate. The practical study of the cutting regimes is illustrated with processing of workpieces in the considered class of machine tools. The research carried out and the results obtained can be applied when using such machine tools.
