Piston Ring Outer Cnc Precision Turning Processing And Testing System Developed

Article introduce source, importance and trends of piston ring measuring system, additional, expatiate the principium and key technique of system.Piston is the one of the most important part of internal-combustion engine. It can operate internal-combustion engine airproof, conduction, oriented and oil-scraped .The geometry and precision of the piston ring also affect on the some aspects of engine棗power, oil-cost, noise, life of cylinder. For the hereinbefore reason, the testing is the key process of the machining.In the past, factories adopt illumination to test the quality of piston ring. It not only speed a great of works also has no precision. Vividly, it can抰 fit for requirement. Now, we use the serious of NC system to process the piston ring and test the end product, so we can feedback the information of the tolerance on time. System can advance the efficiency of the process and shorten the period.System is the mechanical and electronically integrative products. We developed it in W1N98/WINNT, its software is complied by Visual C++6.O, and hardware includes industrial computer, A/D transfer and the equipment of displacement transfer. System is made of two models, one is to simulation of free curve of piston ring, and another is to test the end product. A great part of industrial field, we also run control system in DOS, but windows is more and more popular to be a trend. In the other aspect, with the B/S developed, almost all products should have function of web, so paper also introduces the some technique about XML, COM and discuss the possibility of applied in web.
