“…The methodology of thermal diagnostics of CMMs is presented in the works of Abdulshahed et al [27], as well as Chenyang et al [28]. Hao et al [29] and Muniz et al [30] also worked on similar issues related to thermal errors. On the contrary, Schwenke et al tried to compensate these errors [31].…”

This paper presents the influence of thermal phenomena on areal measurements of surface topography using contact profilometers. The research concerned measurements under controlled and variable environmental conditions. The influence of internal heat sources from profilometer drives and their electronic components was analyzed. For this purpose, a thermal chamber was designed and built. Its task was to maintain and control environmental conditions and, at the same time, separate the profilometer from external disturbances. Heat sources and temperature values for elements and systems were determined. It further enabled for the calculation of the displacements in axes as a function of temperature. The largest displacement in the probe due to internal heat sources for the considered cases occurred in the X-axis direction. Its value reached 16.2 μm. However, the displacement in the probe in the Z-axis direction had the greatest impact on the measured surface topography. These displacements for a thermally unstable profilometer reached 7.9 μm in Z, causing results even 90% greater than in the case of a device without such problems. The time after which a proper topography measurement can be started was also determined basing on obtained data. This time for tested profilometers was between 6 and 12 h. It was found that performing thermal stabilization of the profilometer significantly reduced surface irregularity errors. The stabilization time should be determined individually for a specific type of device.

“…The multi-level nature of dilatometric analysis and the use of such methods for various analytical tasks related to the characteristics of materials have led tools based on this type of method to be successfully used in widely understood materials science [18][19][20][21][22][23][24]. Additionally, the ease of use and the mostly simple geometry of the sample make dilatometry a productive tool for thermophysical materials testing.…”

Due to rapidly progressing development in the field of materials used in the automotive industry, research methods enabling the validation of the properties of materials used in specific applications, e.g., engines, are gaining importance. One such method is dilatometry, which belongs to a branch of physics dealing with methods of measuring the thermal expansion of bodies. It includes assessment study of the dependence of body measurements on external conditions. The authors propose that dilatometric methods could be used to diagnose damage and the causes of engine damage that has already occurred. This is a novel approach in diagnostic methods. The aim of the paper was to validate the proposed method for diagnosing of combustion engine components. Two cases of malfunction of this type of device are presented. In the first case, the subject of research is needle-nozzle holder precision pairs used in engines with a power of 150 kW. The main achievement of the research is revealing the occurrence of different thermal expansion values of the materials in the individual nozzle holders, with specific needles in particular causing adverse changes in clearances between these elements. The other case involved tests with respect to engine pistons. The proposed test method allows for a very accurate and relatively quick determination of the degree of damage to their surface. The conducted research confirms the usefulness of dilatometric methods in diagnosing combustion engines—their application makes it possible to determine the causes for the formation of the irregularities. The presented results are promising and enable further development of the methods and their implementation not exclusively with regard to internal combustion engines.

“…In terms of temperature influence on positioning accuracy, many scholars have studied the control of machine tool thermal deformation compensation, caused by the heat source, the temperature of the machine tool parts would rise and produce heat deformation, then leading to a variety of thermal error such as spindle and dot drift, spindle tilting error [2]. Literature [3] based on least squares support vector machine (SVM) is proposed for nc machine tool thermal error modeling prediction compensation method. Literature [4] by means of finite element technique to the studies on the thermal deformation of machine tool research, with the development of the finite element technology and knowledge of machine tool thermal boundary conditions become more accurate and precision of the presented modeling method is becoming more and more high.…”

The heat of the positioning platform is mainly caused by conduction of each functional unit, when it affected by the influence of internal and external heat source at work, the temperature of units would change, and the condition would make the platform component stiffness change, then lead to positioning platform dynamic characteristics change. In this paper, the finite method analysis platform dynamic connection stiffness with the regularity of temperature change, and by using the grey correlation method to optimize the platform stiffness influence of the four largest temperature sampling point, through the neural network modeling method to establish high precision positioning platform stiffness model, provide theory for the research on platform of dynamic characteristics of the model.
