Construction of knowledge management system for precision machining

Mechanical Industry is a typical technology-intensive industry that is the Taiwan industrial development base. Precision machining includes complex professional technical knowledge. Technician uses a self-understanding way to label the machining setting. This setting implies important technical knowledge, but is difficult to teach others. Furthermore, when changes machining parts, technician needs to review and modify machining parameter and program due to the limit of human memory, Manufacturing process may be delayed when machining adjusting can not achieve program optimization. It is common problem face small and medium enterprises. The topic of knowledge management has wide application in knowledge-intensive industry, but less attention in technical field. Technical knowledge tends to be tacit. Personal tacit knowledge must convert to explicit knowledge, and then personal knowledge is possible to preserve and spread to organization. In this research, we select a typical CNC milling parts in precision machining, systematic analyze machining procedure, and utilize documentation strategy to construct machining knowledge management system. The outcome of this knowledge sharing platform can be a template for other precision machining.
