Title: Study of the Machining Processes in a Type of CNC Lathes Keywords: computer numerical control, drive systems, lathes, machine Abstract: This paper discusses the main features of a type of lathe machines with computer numerical control. Based on formulated requirements to these machines, a simplified block diagram of the drive system is composed. The machining modes and cutting forces are determined by the machining parameters. The basic parameters in turning are the cutting speed, feed and cutting depth. They affect the accuracy, roughness, speed and performance of the whole machine. The methodology applied herein includes a theoretical approach and a detailed experimental study. The practical application is demonstrated with machining of some workpieces. Based on the developed geometric model the machining parameters and the tool life for different materials are determined. Some machining operations are shown and discussed. The energy consumption of the drive system in the studied machines is also analyzed. References Issue
