Design And Realization Of NC Grinding Machine Tool Control System For Rotary Burrs

Tungsten-carbide rotary burrs like a milling cutter with handle, is used in that complex inside of mould machining finish machining work. It becomes a difficult problem to produce this kind of cutter due to shape is complex and little measure. Traditional method using tongs and mould with certain extent handwork to operate. It is not only low efficiency and high cost, but difficult to guarantee quality. In order to solve the problem, a NC system based on IPC, which is used to control grinding machine of the 4-axis rotary burrs, is developed. According to the grinding motion models of the rotary burrs, the grinding of tungsten-carbide rotary burrs is realized through the combination of hardwares and softwares to control the multi-axis simultaneous motion.Firstly the structure of the 4-axis NC rotary grinding machine is introduced, and then fifteen types of grinding motion models are built up. According to function requirements and the development of open NC system, these hardware components such as IPC, motion controller, drive and stepper motor are selected and connected. At the meantime, using G code explainer bring to success NC programme explainer and conversion. The programming of the system is completed according to the demand of software design.Finally, the NC system is used to realize the multi-axis simultaneous motion control of the grinding machine. The trials of all kinds of the rotary burrs are carried on. As a result, the programme of NC system can accomplish work of Tungsten-carbide rotary burrs, the validity and feasibility of motion models are proved. The open NC grinding machine of rotary burrs based on IPC, which is developed firstly by the college of mechanic engineering Tianjin University, has been put into practice successfully.
