This paper presents a generic integration approach to the design and manufacture of scroll type compressors which are becoming popular and widely used in refrigeration and air conditioners. To design and manufacture scroll compressors, however, is not easy for the reasons that their key parts have complex shapes with involute curves. The authors have developed a design approach that can cope with simultaneous design activities concurrently within one single environment. The approach is implemented by using Pro/ENGINEER and Visual C++ programming. The work presented is focused on the integration of Constructive Solid Geometry (CSG) solid modelling, FEM and CAM. With this particular approach a correct and precise solid model can be achieved, which leads to an optimal design in terms of specification adherence, quality, delivery time and cost. The paper concludes with a discussion on the potential and applications of the approach for mechanical product design.
