摘要

Machining processes have various restrictions related to cost, material, production method etc. and design for manufacturability is the key success factor for constructing the best equilibrium between the different aspects of production. In the present paper, to improve manufacturability of a part design, a research on design recommendations for turning, milling and drilling operations was made. This research provided the database for the further step of creating a TRIZ-alike matrix-based access tool. TRIZ is a problem-solving methodology developed by Russian patent inspector Genrich Saulovich Altshuler that takes technical problems as a contradiction of two system properties and uses standard principles to remove the contradictions of the systems. The ultimate aim of the TRIZ is to reach the ideal systems. In order to create the matrix-based access system, technical properties of a chip removal process were defined. Following this step, technical properties are organised in the matrix form and compared with each other. Consequently, contradictions that prevent an ideal chip removal process have been observed and design recommendations, which can eliminate or minimise these contradictions, were placed into the intersections of technical properties. With this study a knowledge database for various contradictions of chip removal process has been established.
