Technology of virtual assembly of machine tool fixture based on typical instance

Aiming at some problems of tradition machine tool fixture such as long design period, low design efficiency and so on, the technology of virtual assembly of machine tool fixture based on typical instance can increase design speed, reduce repetition laboring and satisfy rapid and flexible request of modern manufacture system. Machine tool fixture design theory and realization based on typical instance were proposed. Machine tool fixture searching model, instance organization model, instance modification and reasoning mechanism and instance storage tactics were studied in detail. Computer aided machine tool fixture instance rapid design way based on Pro/E was developed, and a case study was presented. The result shows that the present method is equal to enhance the design efficiency and quality, and should be recommend in the clamp design field.
