Book Description: Applications of precision engineering, generally defined as manufacturing to tolerances that are better than one part in 105, abound and can be found in various semiconductor processes (e.g., lithography, wafer probing, inspection), co ordinate measuring machines, precision metrology systems (e.g., scanning probe microscopy), and robot/machine tools to carry out micro assembly (e.g., micro electro mechanical systems) and delicate short wavelength laser processes. Precision Motion Control(second edition) focuses on enabling technologies for precision engineering issues of direct importance to be addressed in the overall system design and realization: precision instrumentation and measurement, geometrical calibration and compensation, and motion control. It is a compilation of the most important results and publications from a major project that develops a state of the art, high speed, ultra precision robotic system. The second edition has been extensively edited and rewritten throughout with the following particular areas being expanded or added: piezoelectric actuators; fine movement control; gantry stage control; interpolation of quadrature encoder signals; geometrical error modelling for single , dual and general XY axis stages. By providing detailed experimental verifications of the material developed, a comprehensive and thorough treatment of the subject matter is provided in a manner that is accessible to a broad base of readers, ranging from academics to practitioners.
