“…It is necessary to monitor the surrounding environment throughout the measurement process. Monitoring was carried out according to the procedure described in [20]. In both parts of the experiment, circular interpolation measurements were performed with the Ballbar QC20-w, RENISHAW (DBB) for machining without DBB1 compensations and for machining with DBB2 volumetric compensations, according to ISO 230-4 [31].…”

“…This area also includes temperature measurements of machine tools [19]. From publication [20], it is obvious that it is necessary to ensure correct positioning of the temperature sensors in order to obtain valid data for correction of the measured data. Here, this information was used to verify machine stability and to correct the thermal expansion of machine components.…”

Currently, various types of software compensations are applied to machine tools. Their aim is to increase the working accuracy of the tools. The improvement in working accuracy is then further assessed according to the increase in the dimensional and shape accuracy or the surface quality of the workpiece. This publication describes the effects of the volumetric accuracy of a machine tool on the working accuracy of a workpiece, where total roundness (RONt) is evaluated in multiple cuts. In the experiment, two test workpieces are manufactured on a three-axis milling machining centre. The first is made using a standard machine setup while the second with activated volumetric compensation. The LaserTRACER self-tracking laser interferometer is used to compensate for volumetric accuracy. In the second part, verification measurements are performed with a Ballbar, where roundness error is evaluated according to ISO 230-4. Then two test workpieces are machined, and, in the last part, measurement is performed on Talyrond 595S roundness measuring equipment. Finally, the results are analysed and the dependence between the volumetric accuracy, the circularity error of the machine and the working accuracy of the CNC machine tool is established, represented by the RONt of the workpiece. This paper presents new and unpublished relations between the volumetric accuracy of the machine tool and the RONt of the workpiece.

“…Furthermore, devices such as multiple beam interferometers are described in [Holub 2019A]. The main focus of publications [Schwenke 2009] and [Holub 2017] is to find a way how to implement the volumetric compensations as quickly as possible, Furthermore, it is necessary to have access to the machine to appropriately set up monitoring of the ambient conditions of the machine in order to minimize measurement uncertainty in terms of results [Holub 2019B]. It is the elimination of internal and external negative effects that plays an important role in the implementation of volumetric compensations and their resulting impact.…”

“…O autor sugere o fato da temperatura do ambiente ter sido medida fora da carenagem da MF como um dos fatores da baixa previsibilidade do erro térmico. De forma similar, Holub et al (2019) argumenta que é melhor medir a temperatura dentro da carenagem da máquina, de preferência próximo aos atuadores dos eixos.…”
