A Study on an Automation System of NC Sewing Machine
Special Issues Editor (Nottingham Tent University, United Kingdom (Great Britain))
In the sewing process, because of the changes of the material properties and the section shapes, the cutting load has a fluctuation, which affects the cutting precision and the surface quality. At the same time, in different conditions, the characteristic parameters of the cutting load are very different, which makes the dynamic characteristics of the drive system of the CNC sawing machine be not satisfactory, so that the driving system will decrease the efficiency and increase the energy consumption. In this paper, a method of adaptive frequency conversion control with load characteristic identification is proposed, and the corresponding control system is designed. The simulation and experiment show that the speed fluctuation, the load change, and the adjustment time of the control system are very short. The adaptive capability of the driving system of the CNC sawing machine for the load and other parameters is strong. On this basis, the numerical control system based on the real-time detection, the error compensation and the auxiliary machinery intelligent control is developed, which improves the cutting accuracy and production efficiency of the CNC sewing machine.
