Dimensioning and Tolerancing Handbook

Michael D.King
Raytheon Systems Company
Plano, Texas
Mr. King has more than 23 years of experience in engineering and manufacturing processes. He is a certified Six Sigma Black Belt and currently holds a European patent for quality improvement tools and techniques. He has one US patent pending, numerous copyrights for his work as a quality champion, and has been a speaker at several national quality seminars and symposiums. Mr. King conceptualized, invented, and developed new statistical tools and techniques, which led the way for significant break-through improvements at Texas Instruments and Raytheon Systems Company. He was awarded the DSEG Technical Award For Excellence from Texas Instruments in 1994, which is given to less than half of 1% of the technical population for innovative technical results. He completed his masters degree from Southern Methodist University in 1986.
In the recent past, good design engineers have focused on form, fit, and function of new designs as the criteria for success. As international and industrial competition increases, design criteria will need to include real considerations for manufacturing cost, quality, and cycle time to be most successful. To include these considerations, the designer must first understand the relationships between design features and manufacturing processes. This understanding can be quantified through prediction models that are based on process capability models. This chapter covers the concepts of how cost, quality, and cycle time criteria can be designed...
