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.

One of the main problems of machining of moulds is the need for an effective monitoring system of wear of cutting tools. This paper presents the results of coordinate measurements of a cutting tool which were obtained by using the non-contact measuring system based on the ACCURA II coordinate measuring machine equipped with the LineScan laser measuring probe and the Calypso metrology software. Investigations were carried out for several measurement strategies including different measurement resolutions and scanning speeds. The results of the coordinate measurements obtained by using the above-mentioned coordinate measuring system were compared to the reference data measured by means of the InfiniteFocus microscope. The measurement results were analysed by means of two software packages: Focus Inspection and Zeiss Reverse Engineering. The point clouds measured by using the LineScan probe were characterized by the selected deviation statistics equal to 4-6 μm when a good match between measurement points and the reference data was obtained. Moreover, these statistics mainly depend on the measurement resolution. The results of the performed experimental research allowed for drawing conclusions concerning the significance of the effect of the adopted measurement strategies on the results of the non-contact coordinate measurements of the selected cutting tool. The application of the non-contact coordinate measurements to the above-mentioned measurement task may contribute to the development of regeneration methods for cutting tools applied for mould manufacturing.

The analytical and numerical model of the cross-section of the machined layer in the process of milling of concave rounding is presented. Simulation tests were carried out to determine the cross-sectional area of the cutting layer. A strategy has been developed that allows to increase the stability of the cross-section area of the cutting layer when the mill enters the inner corner area.
