The majority of carbide micro cutting tools are now made by a mechanical grinding process starting with an ultra-fine grain carbide rod. Coating materials are deposited on the majority of cutting tools by either chemical vapour deposition (CVD) or physical vapour deposition (PVD). Protective coating materials deposited on micro cutting tools can bring about longer tool life and improvements in cutting performance. Diamond cutting tools for micro machining, for example, diamond micro turning, fly cutting and so on, are notable for their ultra-high hardness and significantly smaller tool edge radius. In micro milling, tool wear and tool breakage are factors of major concern when machining hard and difficult to cut materials. This chapter presents two smart tooling approaches to improve micro tooling technology.
