Research And Development Of Glasses Grinding System Based On DSP

With the improvement of living standards, People require better and better quality for glasses. Glasses machined enterprises have known the importance of high precision and automation equipment optician glasses assembly for quality assurance. Although automatic glasses grinding system has been developed in abroad perfectly, it also not fits the requirement of domestic market for high-price. In domestic, research in this field is still in initial stage, some relative products have been developed, but there are still large gaps with aboard products.This paper states the DSP-based glasses grinding CNC system was researched and developed by reference present development of electronic technology and product-developed experience at home and abroad.At first this paper introduces present state and development direction of glasses grinding system in domestic and aboard, then presents the design program of control system for glasses grinding machine, which is based on the control of machining principles of original prototype glasses grinding machine. After confirming the system's hardware and software development environment, this thesis described specific design of hardware control circuit and implementation based on the TMS320 F2812 DSP, which includes the man-machine interface circuit design with CPLD, Motor-driven circuit design and so on. Finally, it states design of system software including design of the overall structure of procedures and parts of functional module, such as HMI program, Stepper Motor driven program, machined process based on F2812 DSP, and it has finished the adjustment of parts of functional module.
