The Application of CATIA Parameterization in the Rapid Design ofthe Special Fixture;

Aimed at characteristic that many standard parts are repeatedly used in designing special fixture,by taking VB6.

Based on the analyze of process of special fixture design and application situation of fixture CAD technology, this paper presents the structure of fixture CAD System of scheme design by expert system principle and structure design of fixture based on 3D feature modeling.

Interim plate is an important part of the steel-plastic extruding die, made a special clamp in the lathe turning procedure,guaranteed the precision, and enhanced the work efficiency.

Introduced a special clamp applied in batch manufacture copper electrode, the clamp is simple, exchange performance is good in various machine, improved location precision in EDM machining, cutted clamp time, enhanced precision and productivity.

This paper analyzes the features of combined clamp, compares the combined clamp with unit clamp, and introduces the advantages of combined clamp and its wide applicability.

Taken into account the machining cost, practicability and maneuverability, based on the traditional machining technology, a kind of newly developed brazed diamond trepanning tool and special clamp were designed to machine engineering ceramics.
