Foundations of Mechanical Accuracy by Wayne R Moore – 1970
A landmark reference work published by Moore Special Tool Company exploring the fundamental principles of achieving extreme precision in manufacturing and metrology. The book is structured around four pillars of mechanical accuracy: Geometry (flat surfaces, straightedges, squareness), Length Standards (linear measurement, gauge blocks, international standards bureaus), Division of the Circle (angular measurement and precise circle division), and Roundness (spindle accuracy and hole geometry). Includes extensive coverage of universal measuring machine techniques, detailed analysis of cast iron properties (notably Meehanite) and the effects of temperature and humidity on dimensional stability. Features an introduction by Dr. George R. Harrison of MIT and traces the historical evolution of measuring instruments, jig borers, and ruling engines for diffraction gratings. 357 pages of detailed illustrations, diagrams and technical explanations for machinists, toolmakers, metrologists and precision engineers.
