Abstract
The designers' heuristic approach has been the subject of research, with a view to developing algorithms that can be used in automated design systems. However, apart from some general achievements, viable results are not sufficiently available to be employed in machine tool design procedures. The existing algorithms suffer serious deficiencies, restraining their viable use. In pursuit of a total solution, the current authors have proposed an enhanced methodology on the basis of a weighted priority system that can be used for various steps of machine tool design practice and competitiveness evaluation procedure. The core idea of this methodology is based on prioritization of design factors. The weighted priority orders of input information and the degree and intensity of connectivity existing between input information and design factors are used to decide the priorities of design factors. This methodical approach can assist in developing consistency among the designers throughout design procedures, improving competence of young engineers, and developing total solutions and CAD programs. Its applications have been illustrated by examples of layout, assembly, and component design for machining centres and lathes.
