Design of Aircraft Structures For “Mass Production” 490212
SINCE “mass production” cannot be defined, our problem is to design for any specific quantity. To determine the suitability of the design for the quantity, a cost criterion is proposed.
An examination of cost factors and the distribution of costs at various quantities shows the relative importance of each, so that our production design effort may be better directed.
The principles of design producibility are shown to be directed toward minimizing our tooling and manufacturing problem. A detailed study of the material and assembly problems attempts to set forth the more exacting requirements of new design trends.
A set of principles is set forth as a guide for more realistic production design effort. The principles emphasize the necessity for staying within the design, material, tooling, and manufacturing limitations of any organization, in other words, employ only “sure-fire design” practices.
