Abstract

Design for Quality Manufacturability (DFQM) is a design tool that empowers engineers to create designs that are easily and effectively transformed into manufactured products. The goal of this methodology is to make designers aware of design characteristics that may lead to product defects during the assembly process. Acknowledging the possibility of these defects will enable the designer to institute design modifications early in the design phase. The benefits realized in this approach are a reduction in the number of defects in the finished product, reduced product cycle times, a reduction in monitoring costs and a reduction in time-to-market.

This thesis supports the application of the DFQM methodology as a means of maintaining a competitive advantage within industry. The value of utilizing this approach is proven by the submitted case studies of quality defects. An automobile emergency brake, portable overhead projector, car door handle, hand soap dispenser, floppy disk drive and hand held hair dryer were analyzed using the DFQM classes of Manufacturing Quality Defects. Through this analysis, Influencing Factors and Factor Variables of the each design were isolated and suggestions for modifications were presented to eliminate these quality defects.
