Manufacturing Chain

Inspection is an essential part of the entire manufacturing chain providing measurement feedback to the process planning system. Fully automated machining requires automatic inspection process planning and real-time inspection results feedback. As inspection process planning is still based on G&M codes containing low-level information or vendor-specific bespoke routines, inspection process planning is mostly isolated from machining process planning. With the development of new data model standards STEP and STEP-NC providing high-level product information for the entire manufacturing chain, it is achievable to combine machining and inspection process planning to generate optimal machining and inspection sequences with real-time measurement results feedback. This paper introduces an integrated process planning system architecture for combined machining and inspection. In order to provide real-time inspection feedback, On-Machine Inspection (OMI) is chosen to carry out inspection operations. Implementation of the proposed architecture has been partially carried out with a newly developed data model and interpreter software. A case study was carried out to test the feasibility of the proposed architecture.

Feature Based

A feature-based process planning approach for fineblanking-forming-stamping parts is discussed in this paper. To reduce the dependence of experience designers and improve the design efficiency and quality, a prototype of feature-based process planning system has been established. The system consists of four major modules: forming process recognition, feature representation, operation sequence design and parametric feature modeling. The graph-based process recognition and feature representation methods are introduced. The knowledge-based methods are also used for process planning. An application example is illustrated.
