[Abstract]:With the wide application of PC in industrial control field, open CNC system based on PC has become a research hotspot. As a typical numerical control product, engraving machine has broad market prospect in advertisement making, mould manufacturing, building decoration and so on. Combined with the present situation and development trend of the computer numerical control engraving technology, this paper analyzes the characteristics, modes and communication forms of the CNC system of the engraving machine based on PC. This paper presents a software architecture of open CNC system based on PC USB 2.0 digital pulse servo interface card. The hardware and software design, development and test of the prototype are completed. The CNC system of the whole software engraving machine realizes all the management and control functions of the NC system by using the powerful computing ability of PC platform, including: program management, instruction decoding, rough interpolation operation, USB communication, OpenGL simulation and man-machine interface, etc. In order to simplify the connection between the system and the machine tool control interface and obtain the high speed data transmission ability, the system uses the EZ-USB FX2LP interface chip of CYPRESS to realize the USB2.0 bus data transmission between PC and the digital pulse servo interface card. The interface with machine tool control is a digital pulse servo interface card with FPGA as the core. On the one hand, it realizes USB communication control with PC, including read and write control of EZ-USB data, data buffer FIFO across clock domain, etc. On the other hand, the precision interpolation pulse output and the I / O control function of other machine tools are completed. The system has the advantages of simple structure, convenient wiring, high hardware integration and high reliability. The results of system alignment show that the function and performance of the prototype system meet the expected design requirements.
