The Development Of Database Query System Of Laser Process

Since laser was invented in the 1960s, its applied potential in the machining aspect got much recognition. Laser machining adopts high-po\ver-density laser beam to perform heat machining. It has many special advantages in material machining, which is hard to realize for traditional machining techniques. After many years' research, laser-machining processing series have come into being, and have applied in many fields. With the continuous development of laser-machining application, all kinds of process performance parameters and data have been largely accumulated. How to effectively utilize these data to supply references to manufacture is a pressing problem to solve. To set up datasbase query system of laser machining is one of the effective solutions. At present the reports about database query system of laser machining are comparatively scarce either domestically or abroad . This thesis initially designs the database query system of laser machining to meet these requirements. The system establishes as a simple Client/Server net model, it can meet the requirements of modern corporation's network and integration.The system primarily includes principles bank module , industry application bank module ,database maintenance module and economy evaluate module . The core of system is industry application module which can provide directional process parameters. The query system can realize the query and output of the basic process theory, the information about laser equipment and important process parameters of laser welding , laser cutting and laser surface treatment. It also can estimate whether the adoption of laser-machining technology can suit to practical production and economic request. This system provides database maintenance function, and users can briefly append, delete, modify the data of the database so as to make it gradually perfected. The storage of the technology and data will be helpful for further research, such as laser-machining expert system's foundation, etc. The help module can make users master the principle in a short time.
