Automatic generation of computer aided process planning and CNC code for rotary parts using geometric and topological similarity

In this work, ”Automatic generation of CA PP ami CNC code for rotary parts using geometric and topological similarity”, that were developed to meet the needs of fast- changing product design cycle and lower batch production volumes to achieves flexibility with a certain degree of intelligence. The system uses case-based reasoning methodology. Briefly, case-based reasoning (CBR) is an intelligent problem-solving technique which works by searching through a database for previously solved problems for one or more cases whose identifying features closely resemble the current problem. The case-based reasoning system used in this work to develop a process plan, typically consists of three modules, i.e. the part input and representation module, the case retrieval, and case adoption module. CBR combines the advantage of the generative and variant approaches by reusing old solutions automatically or planning generatively when no appropriate old solution exists.
