Braking Energy Recovery Hydraulic System for Heavy-Duty Machine Tools. Mathematical Modeling and Simulation

Abstract

This paper examines the opportunity to recover the kinetic energy accumulated by the main kinematic chains of the heavy-duty machine-tools in downtime phase. The proposed unit can shorten the stopping time of the main spindle, with or without a blank, and would allow the recovery and storage of the accumulated kinetic energy in order to use it in a new start. The paper presents a basic diagram, and also the results of the first simulations.
