“…Dimensions and geometric tolerances, as the most fundamental process parameters of mechanical parts, have a significant effect on the mechanical properties of the parts and the fit between the parts 28 . A three-coordinate measuring machine can accurately measure the dimensions and geometric tolerances of parts 29 . This study used a threecoordinate measuring machine (ZEISS CONTURA) to measure the diameter ∅13±0.02mm and roundness O0.01mm of the structural common specimens.…”

In the mechanical cutting industry, trial production is used for predicting and evaluating the quality of product processes before batch production, and it can be expressed through the qualification rate. However, it cannot objectively and comprehensively evaluate the quality of product processes. This study optimizes the analysis of outliers and stability in mathematical statistics to better apply it in the mechanical cutting industry; then, it combines them with process capability analysis. Simultaneously, considering the non-normal distribution of process parameters, a batch production-prediction model is proposed. The diameter, roundness, and roughness of structural common samples are verified. The results show that after the diameter, roundness, and roughness stabilize, the process performance indices are 2.5157, 3.8883, and 3.5878, respectively, adhering to the standards for batch production. For other mechanical parts in the mechanical cutting industry, the model proposed in this paper can be used to quickly and accurately predict and evaluate batch production.

“…The examples of currently applied coordinate measuring systems are coordinate measuring machines (CMMs) [3,4] with touch and non-contact measuring probes, photogrammetry systems, computed tomographs [5], measuring arms [6] and CNC machine tools equipped with measuring probes [4]. The capabilities of the selected laser measuring system were verified by the authors of the work [7]. They compared the measurement results of the considered non-contact system to the results of measurements obtained by using a CMM.…”

The paper presents a new method of analysis of a controlled radius (CR). The presented method was verified based on simulations of coordinate measurements and during real measurements conducted on the selected coordinate measuring machine (CMM) -ACCURA II. In addition, the investigations were conducted by means of the Calypso metrology software and the Python programming environment. Computer simulations were performed for the selected dispersion of measurement points relating to nominal data of measured products. The actual coordinate measurements were conducted by using various measurement strategies. The created method takes into account the analysis of flattening of a considered curve, for which the measurement characteristic CR is determined. The analysis was conducted based on linear regression. The advantage of the presented method is the possibility of its implementation in software of a CMM and, consequently, the use of the above-mentioned method in industry. The new method detected flat fragments of measured objects regardless of the applied number of measurement points.

“…Measurements conducted by using a CMM can be performed in two modes -contact and non-contact. Altinisik B. et al [10] found that the choice of the type of a measuring system mainly depends on the accuracy of measurements, as well as on the complexity of the geometry of a tested object. In the case of measurements of a cutting tool, it is reasonable to use a non-contact measuring system.…”

The article presents the results of research concerning the analysis of the possibility of the innovative application of the LineScan non-contact laser measuring probe controlled by the ACCURA II coordinate measuring machine in the field of measurements of a selected cutting tool. In the study, the angle of a round cutting insert was measured. The influence of the selected elements of a measurement strategy i.e., the scanning speed v, the resolution k, and the number of measurement paths w on the repeatability of measurements and the value of the insert's angle was determined. In both cases, the number of paths had the greatest impact. The best repeatability was obtained for the smallest distance between points (k = 0.1 mm) and the largest number of paths (w =10). For those measurement strategies, which differed in the scanning speed (1 and 3 mm/s), the detailed GR&R analyses were carried out by using the ANOVA and EMP methods. For strategies with the scanning speeds of 1 and 3 mm/s, the variance of the measuring system was 0.9% and 0.5% of the total variance, respectively. However, these differences in repeatability were not statistically significant. It has been shown that the selected methodologies of measurements and measurement data processing ensure good measurement repeatability of the selected geometrical feature of a cutting tool.
