Abstract

The study develops an Expert System approach to generate alternative process plans for mechanical parts with tolerance requirements. The knowledge base incorporates six factors: process selection, machine specifications, tool election, machining parameters, fixture selection and process capability. The EXSYS program has been used to manipulate the knowledge base. It starts to extract and verify dimensional and geometrical tolerances for each machining surface. Then, it selects all possible processes, machines and tools. Alternative groups of machines and tools are first verified by the machining parameters required to machine the part. Then, the operation index generated by statistical process control is used to verify the practical feasibility of each of these groups. The potential operations are then grouped to form alternative process plans. Operations in each process plan are finally sequenced using an optimization algorithm and a total cost for all operations is calculated. Application of the program to a mechanical part is illustrated.Dept. of Industrial and Manufacturing Systems Engineering.
