EFFECTS OF COOLING SYSTEMS ON THE THERMAL BEHAVIOUR OF MACHINE TOOLS AND THERMAL ERROR MODELS
Journal of Machine Engineering, 2020 Today, cooling systems are increasingly applied to the structure of machine tools (MT). Unfortunately, to date there have been few efforts to precisely control these cooling systems, which inhibits the full utilisation of their potential to improve MT thermal behaviour (to reduce thermal errors). Moreover, the effects of cooling systems, especially the

Advanced Engineering Materials, EarlyView.This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐
