Fig. 1: Short and Rigid tool can cut this. Design Guide This document will outline some Design suggestions or factors that drive the costs of machined components. It will help the engineer make choices during the Design process which may reduce the cost of the end product. Choosing Materials: When choosing materials, allow the use of different forms of the material such as bar stock and plate. There can be significant differences in the cost and lead time of acquiring different forms. The Table below shows approximate $/lb and machinability ratings for common metals. Consider the strength vs. machinability rating as well when choosing materials. Choosing an annealed but heat treatable alloy of steel for example and then not specifying any heat treat will just drive cost with little benefit in material performance.
Fig. 6: A larger wall than floor radius is much faster to machine. Fig. 7: This part could be cheaper if it were a little thinner. floor radii can be, the better, with a …
