Abstract:

The generation of an efficient algorithm for easy understanding of machining features in a CAPP is much difficult. A simple logic is always needed for complex machining features. The CAPPS module contains feature extraction; feature recognition and machining process planning for each and every hole are discussed. In this paper a framework has been engendered for the integration efficient setup sequencing for machining of 2.5 Dimension prismatic parts considering each and every hole as a feature. An efficient algorithm has been developed to easy understanding the task. These algorithms can be applied for automated process planning of2.5D parts irrespective of the nature of fixture used. In addition, an improved version of CNC has been presented along with J2EE software programme. The algorithms have been implemented as part of a feature-based CAD/CAM environment, G and M codes have been generated for a selected model and simulation for entire operations also presented. The cutting tools, machining parameters, setups and fixture configurations evaluated. Finally, the rationality of the process has been verified by experiment considering a wooden block of specified dimension and results have been discussed.
