This newly revised text presents the basic concepts of the design of workholding devices. Topics covered include the basic types of jigs and fixtures commonly used, the principles upon which the design of these devices is based, and practical applications of jigs and fixtures. Stron coverage of geometric dimensioning and toleracing, modular tooling systems, power clamping and low cost tooling is included. Numerous part drawing problems and review questions provide extensive application of text material. This book should be of interest to students of FE colleges on mechanical drafting or machine technology disciplines.
