Modeling and simulation of feed system of numerical control lathe based on MATLAB

In the industry, CNC machine tools plays a irreplaceable role. It not only realizes the rapid industrial production, but also saves manpower and material resources. It is the symbol of modernization. As an important part of CNC machine tools, feed system plays a very important role on the processing process, It refer to the product's quality problems. According to the principle of mechanical dynamics, I establish a mathematical model of machine tool feed drive system and use Simulink(dynamic simulation tool) in MATLAB to construct the simulation model of the feed system of lathe. We contain the simulation curves of the system performance. Also I joined the space module analysis. These efforts offer effective foundation for the improvement of CNC machine tool.
