Applying rapid heating for controlling thermal displacement of CNC lathe [PDF]
Archive of Mechanical Engineering, 2022 Thermal error always exists in a machine tool and accounts for a large part of the total error in the machine. Thermal displacement in X-axis on a CNC lathe is controlled based on a rapid heating system.

The International Journal of Advanced Manufacturing Technology, 2023 The time-varying thermal error of the horizontal boring and milling machine tool (HBMMT) directly affects the performance of high-end parts. The time-varying thermal error is in the axial direction due to the radial symmetry of the spindle box being good.
