Thermal error monitoring technology is the key technological support to solve the thermal error problem of heavy-duty CNC (computer numerical control) machine tools. Currently, there are many review literatures introducing the thermal error research of CNC machine tools, but those mainly focus on the thermal issues in small and medium-sized CNC machine tools and seldom introduce thermal error monitoring technologies. This paper gives an overview of the research on the thermal error of CNC machine tools and emphasizes the study of thermal error of the heavy-duty CNC machine tool in three areas. These areas are the causes of thermal error of heavy-duty CNC machine tool and the issues with the temperature monitoring technology and thermal deformation monitoring technology. A new optical measurement technology called the ''fiber Bragg grating (FBG) distributed sensing technology'' for heavy-duty CNC machine tools is introduced in detail. This technology forms an intelligent sensing and monitoring system for heavy-duty CNC machine tools. This paper fills in the blank of this kind of review articles to guide the development of this industry field and opens up new areas of research on the heavy-duty CNC machine tool thermal error.

“…This way could shorten the error from 0.075mm to 0.016mm and the time for trying error by vanishing to decrease the thermal error. For the tool center point, Mr. Horejša, Mareša, and Novotnýa [7] used MLR and TTF to develop an advanced thermal compensation in horizontal 4-axis machine tools. Different from original 21 sensors, 4 are utilized by multiple regressions.…”

Abstract. This paper focuses on analyzing and discussing thermal errors at CNC milling machines. The thermal affection makes the deformation of machine tools and is the main problem of accuracy error over than 65%. Effectively improving or controlling thermal errors is helpful for the accuracy of machine. The key point of this paper is the position of tool center point. Firstly, 14 pieces of temperature sensors are used for checking the real field of temperature, and then four sensors with better linearity are chosen for real situations. The test bar and 5 pieces of noncontact sensors are utilized for clearly getting the displacement of the tool center point and head during the process. Based on the theory of MRA (Multiple Regression Analysis), the external zero-point is shifted to build the mathematical module. The database is input to the control board and the PLC is used for real-time compensation for machining. Finally, two work pieces (one compensated and one non-compensated) are tested and compensated one presents better precision.

“…Heat fluctuations can cause spatial thermal gradients in a machine tool, and the heat flowing through the structure over time results in non-linear thermal-elastic deformations, which substantially deteriorate the accuracy of machine tools [2,3]. Thermally induced error caused by environment or internal heat sources can contribute more than 50% to the overall geometrical error of machined workpieces [4].…”
