Losses caused by the presetting of tools by the manual method

摘要

In the search for competitiveness machining companies are applying concepts of lean manufacturing, like the fast setup, for the elimination of losses in the process. However, most of the companies users of CNC machines still face a significant barrier in this field: the presetting of tools is usually performed manually, and requires high times for the preparation of the machines. In this paper the losses in production caused by the manual presetting operations are detached, showing the results in terms of delays generated in the setup operations of machines, and also the reductions in the utilization rates of CNC machines.
