Add to basketPaperback. Condition: New. Print on Demand. This book details how precision gage blocks are the standard tools used in the manufacturing shop to check micrometers and other measuring instruments, for precise mechanical work, and as distance pieces or size blocks. The author, a physicist, was tasked with finding a method for calibrating these gages that would be more accurate than any that had been previously used. The problem was solved by using the interference of light waves as the standard for the measurements, instead of relying on measurements of the expansion of a mercury column or the turning of a micrometer screw. These optical methods rely on the precise and reproducible measurement of the wavelengths of light thus establishing gage blocks, traceable to the international standard of the meter, as the new standard for length measurement. The author describes the tools and methods used to measure very small distances, including an optical system for testing plane surfaces and parallelism of surfaces and a method for determining the length of a gage by means of light waves. This book chronicles the development of a practical system for the calibration of precision gage blocks using light waves, offering a comprehensive overview of the principles, procedures, and tools employed in the field of precision measurement. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
