The Development of a Feature-Based Fixture Process Planning System for Flexible Assembly
This paper presents a prototype feature-based fixture planning system for flexible assembly. Fixture process planning prepares the fixture clamping position and orientation for the base part. In a heuristic way, a group of guidelines were generated to help find the feasible solution for automated fixture planning based on the geometries of the workpiece and the nature of the selected fixtures. By representing the geometric and nongeometric properties of fixtures and workpieces in terms of features, a fixture process planning system was implemented using a knowledge-based approach. A rating technique for feasibility evaluation was used to include all the active facts into an optimal solution. Through this analysis, a product can be evaluated for its manufacturability, cost, and cycle time at the product design stage.
