Design of Precision Machines

Abstract

Precision machines are essential in modern industry and directly affect machining accuracy, repeatability, productivity and efficiency. Generally, the design of a precision machine mainly includes the design of its key elements such as mechanical structure, spindles and drive system, control and inspection systems, etc. There is a lot of literature available on the design of machine elements [1-5]; while it is difficult to cover in details on design of precision machine in one chapter. In this chapter, therefore, emphasis is placed on the mechanical and structural design of precision machines, relevant design methodology and tools driven by dynamics. Furthermore, the chapter focuses on the integrated approach for modelling and simulation of the machine and machining dynamics, and thus achieving an optimal design of the machine and its performance in the dynamic machining process.
