The ability to quantify part dimensional quality with respect to design specifications is of fundamental importance in product design and manufacturing. Our earlier work has proposed the use of admissible transformation volume as a part dimensional quality metric. That is, part quality is quantified based on how much an as-manufactured part shape can move while still remaining within a tolerance zone. A transformation is admissible if upon such a transformation a manufactured part shape falls within the design tolerance zone. A collection of such transformations in the transformation space forms an admissible transformation volume (ATV). In this paper, we present two properties of ATV: transformation invariant and decomposability. We then describe algorithms for computing ATV and how ATV properties facilitate complex tolerance check and reveal new insight on part producibility.

A Product Design and Manufacturing (PDM) Engineering emphasis has been designed to update a Manufacturing Engineering program at Grand Valley State University. While the program continues to include a major focus on manufacturing it also emphasizes crossing disciplinary boundaries for product design. Graduates of the program are educated to work in all phases of the product development process from concept to customer. The program includes a blend of courses from a variety of disciplines, tieing these together using a sequence of product design courses. Within the courses students are exposed to course work that encourages product oriented design including prototyping. The program redesign described in the paper could also be applied to Mechanical Engineering programs.

As diversification is quickly increasing, industries are making tremendous efforts to cope with it. But this paper points out that these efforts are too much producer-centric. Our customers are not passive consumers as most industries assume. They are very active and would like to customize our products to their own needs and to their preferences. We should note that this act of customization is deeply associated with our basic need of self actualization. That is why their requirements are diversifying. We have to change our product development much more to customer-centric. New emerging technologies such as 3D printers enable them to get involved in product design and manufacturing. But if we consider the capabilities of the present states of these technologies and expertise of our customers, it is much easier to realize such customer-centric product development, if we extract the feature parts or feature points from a product that relate to personalization and let our customers develop them with the help of us, experts. The parts that do not substantially contribute to personalization may be developed as a common platform and these parts can be developed by experts without customer’s involvements. In this way, customers would feel they are actualizing themselves and would be more satisfied.
