Precision Spindle Metrology furnishes the mathematical tools to understand--and correct--various kinds of motion and rotational errors.

Using case studies and practical examples, the book explains how to set up devices for measuring spindle motion. It then presents a detailed analysis of precision spindle metrology data and demonstrates how the data can be utilized to understand and improve the performance of spindle-based machinery, measured to the nanometer level.

Features:

• Newly updated and corrected, with improved illustrations
• Theory and practice of measuring spindle motions at the nanometer level
• For turning, milling, and grinding machines, and production and inspection machinery of all kinds
• Clear explanations of the methods and mathematics of data analysis

This volume is a revised version of the original, which is the chief introduction to the fundamental concepts and technology of measuring spindle motion. The new edition has been updated with clearer examples and explanations, as well as improved illustrations.
