Optimal tempering of machine tools by interconnected components and processes

Cyber-physical components, enhanced controllerfunctionalities and the possibility to gather and analyze amultitude of data in production systems offer a broadvariety to optimize machine tools in accordance with thecorresponding processes. Thermal issues however arestill one of the main failure causes in today's machinetools. In order to increase production accuracy in conjunction with a tolerable energy demand, one key enable is to harmonize the temperature field by means of a ""thermal pre-control"". After an insight to extended possibilities of cyber-physical production systems, the paper presents a strategy to enable CNC controllers to influence beneficially the temperature field of machine tools. The course of action comprises three major steps.
