This thesis is aimed on proposal of production technology, NC codes and production of selected hinge part. The theoretical part describes the technologies of milling, surface grinding and hole grinding as technologies used during production and as non-production technologies of CAD/CAM software. Selected production machines and cutting tools are also specified and a technological process is proposed including all the steps and operations for the production of the hinge part. According to the proposed production plan, the work in two different CAM systems for the NC code of the machining center is described. The practical part describes the production on a CNC machining center and grinders. The economic evaluation summarizes material costs, ...
