The processing quality of machine tools (including size, shape and position accuracy and surface quality) mainly depends on the structural rigidity, geometric accuracy, motion accuracy and positioning accuracy of machine tool equipment (including tools and fixtures), and of course environmental conditions (such as temperature, vibration, etc.) control and assurance. Therefore, it needs to be solved by developing precision, high-precision and even ultra-precision machining technologies and machine tools.
Production efficiency is mainly measured by the production cycle of parts from blank to finished product. The production cycle of parts includes the time required to directly change the properties (performance) and (shape) of the part material (such as cutting and forming, heat treatment, etc.) The time required for waiting, transmission, detection, adjustment, clamping, etc.) is composed of two parts. In order to reduce the cutting time, it is first necessary to increase the cutting speed and feed rate. To this end, people have developed high-speed cutting technology and machine tools, and in order to shorten the non-processing time, people have to develop more technical measures and equipment, including mechanical automation, CNC flexible machine tools and production lines (manufacturing systems) and are now in The booming CNC composite machining machine tools, etc.
Processing costs include direct costs (such as material consumption, energy consumption, worker wages, etc.) and indirect costs (including depreciation costs for plant and equipment, safety and environmental protection fees and management fees, etc.). In order to reduce costs, there are many problems involved here, including technical problems and organizational management problems, so more comprehensive research is needed to solve them.
