Abstract This research focuses on the development of an object-oriented case-based process planner which combines the advantages of the variant and generative approaches to process planning. The case-based process planner operates on general 3D prismatic parts, represented by a collection of features (eg: slots, pockets, holes, etc.). Each feature subplan is developed by the case-based planner. Then the feature subplans are combined into the global process plan for the part via a hierarchical plan merging mechanism. Abstracted feature subplans correspond to cases, which are used in subsequent planning operations to solve new problems. The abstracting and storing of feature subplans as cases is the primary mechanism by which the planner learns from its previous experiences to become more effective and efficient. The computer-aided process planner is designed to be extensible and flexible through the effective use of object-oriented principles.

Theory Application

Realization of the control programs for controlling of the numerically controlled (NC) manufacturing machines is very important in manufacturing practice in this time. Manufacturing process of the parts with complex and free form figures is realized by NC manufacturing machines application. It is very difficult without application of personal computers with special software. Very often this software can be Computer Aided Manufacturing (CAM) system. These programs for control of NC manufacturing machines can be realised by other methods, too. In paper is presented new method of NC programs preparation by Group Technology theory application.

ISO 14649, known as STEP-NC, is new model of data transfer between CAD/CAM systems and CNC machines. In this paper, the modeling based on machining feature is proposed. The machining feature comes from the manufacturing process considering the restriction of machining technology and machining resource. Then the framework for computer aided process planning is presented, where the algorithms of operation planning is studied. The practical example has been provided and results indicate that machining feature based model can integrate with CAPP and STEP-NC seamlessly.

Abstract Fixture planning is an indispensable part of a manufacturing process planning routine. This paper introduces a rational approach to computer-aided fixture planning (CAFP). A method of fixture classification and selection is introduced for planning of modular fixtures. The location of each fixture component is determined according to the common fixturing principles. We has developed a prototype CAFP system and linked to a commercial CAD system, namely CADAM. Modular fixture elements are automatically selected by the system, and the generated fixture layout can be displayed on-screen after assembly. For verification and optimization of a fixturing scheme, a fixture analysis module is also developed. An iteration method is used to solve the fixturing constraint equations and to determine the adequate clamping forces for holding the workpiece during machining processes.
