Energy Efficiency in Machine Tool

Reduction of energy consumption in manufacturing processes are becoming necessary due to the growing concern of industrial pollution and of electricity prices over time. Several factors such as raising of process automation, fluids consumption, process parameters selection and motion control influence the energy consumption. The consistent motion control on CNC machines are the most important for the machining process and are achievable by main drive control and auxiliary drive control. Positioning along lengths of travel can be linear (driven along a straight path) and rotary (driven along a circular path). Over the decades, mass of the machine tool is decreasing, and speeds are increasing what influence necessary kinetic energy for motion. Integrated Kinetic Energy Recovery System (KERS) on machine tools is one possible solution.
