The micro grinding machine tool was built up with a combined support structure of both advantages of gantry column and single column structure, allowing more work zone and better static stability. In order to improve the dynamic performance of the machine tool, an optimization design method based on sensitivity analysis was proposed.
Micro-grinding technology can meet the demand for complex structures and micro-characteristic, especially for hard and brittle materials with desired surface integrities (Pratap et al., 2016). Micro-grinding is widely used as an effective method for machining thin-walled parts, which have low stiffness and high removal rate.
This study is focused on the optimization of the grinding process parameters for the grinding of the CVD diamond micro-milling tool. Two types of CVD diamond i.e. CDM and CDE are used for the study. Feed rate and the grinding velocity are used as the grinding parameters. The optimizations of the parameters are done by studying the two results i.e. grinding force and cutting edge radius.
