V2 - 2000b Cnc Machine Tools Transformation

With the development of market economics of China, the competition of domestic and international markets are becoming increasingly acute. Since the contour of aero-product is more complex with higher precision required and the demand of NC machine is increasing gradually, the equipment modification has been an important researching subject in our company currently.The author has performed the further research and analysis for the NC machine modification on the basis of the constant consultation of abundant relative documents, which focuses on describing the design of control system of the machine. NC system is the centralization of the whole control system; the CNC system, electrical control system and the servo system can be operated coordinately and uniformly via the design of programmable controller so as to realize the NC machine. It also describes the content and step of the system adjustment of the whole NC machine, which systematically analyses the PLC control procedure of NC machine, adjustment process of coordinate servo system and the machine-linked operation based on the design of NC machine modification. The NC system has been adjusted and located to optimize the whole control of the machine by adjusting the parameters of CNC machine. The special function of the machine has been developed through selecting its strong compensation function to analyze the reason of error generated and the machine has been modified successfully.
