Management of Machining Parameters Based on Process Planning Knowledge

The selection of reasonable machining parameters in numerical control milling process is the key issue to improve quality and productivity of product as well as save cost. In order to determine the optimal machining parameters instead of conservative ones used at present, a method of machining parameters management based on process planning knowledge was introduced in this paper. On the basis of analysis of process planning knowledge in milling process, an application mode was established, in which the storage, optimization, analysis and usage of machining parameters were considered. Finally, an application case was introduced to the optimization-usage program to validate the proposed system. The result shows that the application mode of machining parameters based process planning knowledge which were applied in NC milling process can shorten parameters selection time and increase productivity.
