Contrary to the fabrication of micro v-groove in ultra-precision fly-cutting. An integrated manufacturing platform is developed to cover micro v-groove design, data transform, micro v-groove model construction, simulation and cutting optimization of multi-axis machining. The adoption of the system shortens the time to develop complex NC programs for different micro v-groove. This system helps to avoid expensive repeated cutting tests, as well as to optimistic the cutting parameters and improve the surface quality of micro v-groove. In addition, the system could predict the surface roughness based on the chosen cutting parameters.
