Precision Machine Design

A precision machine is an integrated system that relies on the attributes of one component to augment the weakness of another component. In this course, emphasis is placed on the design of mechanical and structural precision machine components and their integration with sensor and control systems to maximize performance. In the discussion of the design of components and assemblies, emphasis is placed on how the design will affect overall accuracy, repeatability, and resolution of the machine.
