Tolerance design and its applications – Case studies

P. V. Mohanram

Abstract

In today’s competitive marketplace, companies are under increased pressure to produce products that have low cost and high quality. Product cost and quality are influenced by many factors. One factor that strongly influences both is manufacturing variation. No manufacturing process can produce a part with perfect geometry. In modern manufacturing, tolerance design principles are adopted to manage the manufacturing variation and its effect on product performance and manufacturing cost. This paper presents an overview of tolerance design principles adopted in the design of mechanical assemblies. Some typical case studies on tolerance design are presented to illustrate the tolerance design concepts applicable to practical problems.

Keywords

Tolerance design; tolerance analysis; tolerance allocation; cost-tolerance cost; mean shift; truncated tolerance.
