Abstract


EDM is a mechanical, electricity in one of the advanced manufacturing technology, it has been widely used for its unique processing advantages . Its core EDM machine , CNC system. At present, most of the EDM machine CNC system at home and abroad is a special type of closed , its expensive . In recent years, the EDM CNC system development direction of the open CNC system has good flexibility and lower cost . Open CNC system is designed to establish a modular , reconfigurable , scalable hardware and software system to enhance its functionality and flexibility to the user , leaving more room for secondary development to quickly and economically respond to new processing requirements for the purpose of reducing its production costs . This thesis five-axis EDM milling machine , programmable multi-axis motion controller the PMAC has developed a open CNC system for EDM milling requirements . Meanwhile, in order to improve the accuracy of machine movement , the use of laser interferometer to achieve the detection of each movement axis positioning accuracy , and at PMAC pitch error compensation for each axis , each axis of motion accuracy . The thesis mainly : 1, open CNC system developed a five-axis EDM milling machine . PMAC multi-axis motion controller to build a the EDM milling machine CNC system hardware platform , the development of pulse power discharge control module, pulse power discharge detection module and I / O detection module ; On this basis , the VC 6.0 as a platform , completion of the part of the control program development . 2 -axis linkage EDM milling machine characteristics , the discharge control module, the discharge gap detector module experiment, to ensure good communication between the various modules . 3, using a laser interferometer positioning accuracy and repeatability of the detection of the X and Y axes of the five-axis EDM milling machine . On this basis , each axis leadscrew error compensation and backlash compensation table , and the PMAC pitch compensation and backlash compensation adjustment for each axis servo motion accuracy and improve the positioning accuracy and repeatability .
