A framework of a virtual machining and inspection system for diamond turning of precision optics

This paper describes a framework of a virtual machining and inspection system (VMIS) for the diamond turning of precision optics. The development of the VMIS aims at creating a virtual manufacturing (VM) environment for the design, manufacture and inspection of precision optics through various model-based simulation modules. Basically, the VMIS consists of six building blocks which include the information module (IM), optics design and optimisation module (ODOM), virtual machining module (VMM), virtual inspection module (VIM), analysis and decision-making module (ADMM), and performance evaluation and monitoring module (PEMM). In this paper, the concept, the theoretical basis and the underlying assumptions in the development and implementation of each module are outlined. Preliminary experimental and simulation work together with the future development of the system are also discussed.
