Summary: Two methods have been developed as a result of the research in the project. The application of the method for maximum utilization of single point cutting tool gives the maximum output of the machining system in rough turning. A tool selection method using economic criteria and optimization is developed too. The results obtained in the research in face turning are applicable on CNC machine tools, i.e. the cutting time is shorter for approximately 45% when face turning is done at constant cutting speed, and the surface roughness is smaller. A contribution to the tool wear sensing methods in turning and a contribution to the standardization of machinability testing procedures are given. Also the identification of manufacturing processes applying acoustic emission analysis by neural network is done.

Keywords: Machining, Cutting tools, Optimization of the process, Sensors, Chip control, CAM, CAPP.

Research goals: The complete change of the conditions in the science of manufacturing caused by the application of computer integrated advanced manufacturing systems, brings about a need to change the way of thinking and the approaches in manufacturing science. The same is valid for the practice of manufacturing. In industrial conditions, it is important that the machining system works, and in most cases it does not matter how it works. The productivity of such a machining system is usually much below its optimum value and the machining cost is too high. The aim of the project is to obtain new knowledge in this field in order to come closer to the optimal machining conditions, i.e. to increase the productivity, to decrease the machining cost, to increase the utilization of cutting tool, etc.
