Development of the machining producibility evaluation method: Quantitative machining producibility evaluation for various processes

Abstract

The machining producibility evaluation model (MEM) was developed to assess design quality quantitatively for easier processing of parts and products. It is constructed on the basis of product and process modelling and covers cutting and grinding, metal working, welding, moulding, die-casting and casting. The main features of the MEM are

Quantitative evaluation is carried out by means of an easy-to-understand 100-point scale, and processing cost is estimated within a ±15 per cent error.

It is an easy method to both learn and use, employing approximately 20 basic symbols and five supplementary elements.

This paper provides a description of the theory, the evaluation procedure and the accuracy of the method, and gives application examples.
