Feb 01, 2020· The increasing demand for micro components and features in ceramic materials has led to the development of bonded micro abrasive processes such as micro grinding with micro pencil grinding tools (MPGTs) or thin dicing blades [1,2].Compared to other tool based micro machining processes, micro grinding has several advantages when machining hard and brittle materials [3,4].
The ability to predict the grinding force for hard and brittle materials is important to optimize and control the grinding process. However, it is a difficult task to establish a comprehensive grinding force model that takes into account the brittle fracture, grinding conditions, and random distribution of the grinding wheel topography. Therefore, this study developed a new grinding .
Jul 13, 2017· 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.
Dec 01, 2008· Mechanical micromachining generally consists of various material removal processes. Within these processes, microgrinding is typically the final process step and like conventional grinding, it provides a competitive edge over other processes in fabricating microscale parts such as micro sensors, micro actuators, micro fluidic devices, and micro machine parts.
