Application On The CNC Lathe Of Open Numerical Control System

NC inserting into PC opening CNC system is a popular study field of numerical controlling technology. It has following advantages: low developing cost, friendly person-computer interface, highly opening degree, good universal usage, and so on. This essay will apply the opening CNC system into the improvement of machine tool, which combines IPC and motion controlling. That will realize its norma run of CK0625.The writer describes its general condition of development and its fabric system of opening NC system as well as analyzes the hardware and software construction of CNC in detail The writer also analyzes the detailed way of realization and offers a main framework of CK0625 opening CNC system on that base. The wr ter will express the whole system process with the support of hardware clearly so that lays a good foundation for the practice and realization of CNC system.The writer elaborates the processing of input data, which is the key technology. According to the reforming demand, the writer designed a systematical person-computer interface and confirmed the system command of CK0625 as well as designed the input way of CNC processing. On the base of detailed analyzing the coding, cutting tools' radius compensation and length compensation, the writer designed a flow chart of coding and cutting tools' compensating software. That will realize the encoding program of cutting tools' compensative function, single cycle, compound - fixed cycle, simplify the program processing of NC production and improve the productive efficiency.The essay researches the application of frequency control technology in spindle drive system and the adjustment process of half closed-loop serve circuit, and solve the communication between IPC and frequency converter and the communication between controller and feeding serve machine. That realizes the spindle's functions of stepless timing ,two axis linkage and automatic tool changer.A large number of experiments show that the CK0625 machine tool can monitor and show the production process in time, make the each basic function of machine tool NC reach the routine requirements that numerical control should possess.
