Book 1991annot be avoided, and it is therefore necessary to define measurement tolerances. This book offers a comprehensive presentation of tolerance problems and their solution by statistical methods. All calculated solutions are presented in clear figure or graphical form. It is particularly appropriate fo

Introduction,is impossible to manufacture technical products in accordance with exact theoretical dimensions. In fact—depending on the variability of technical resources—some deviations from the theoretical dimensions are unavoidable, and these deviation may be either assignable (systematic) or unassignable (ran

Process Control,ed out successfully if a continuous QCC is used. This is not problematical if microprocessor controlled measuring machines are used, which store and statistically compute measurements from several measurement stations and can output the results in tabular form of several measurement stations or as Q
