Along with Boothroyd, Peter Dewhurst and Winston Knight (both U. of Rhode Island) share with practicing manufacturing engineers and designers the results of their research into methods for designing products for manufacture and assembly. They do not mean the reference to replace the software that Boothroyd and Dewhurst have developed, which contains more elaborate databases and algorithms, but to serve as a handy companion. It provides the basic equations and data that allow manufacturing and assembly cost estimates to be made, so that for a limited range of materials and processes, engineers can make cost estimates for real parts and assemblies, and so become familiar with the details of the methods employed and the assumptions made. The second edition contains new chapters on the processes of sand casting, investment casting, and hot forging. No date is revealed for the first. Annotation c.
