“…This present paper provides a detailed view of the strategy and techniques for describing the tool profile that is optimal for use in the production of gears using a hobbing mill. This highly efficient production process is used very often nowadays and, therefore, measures aimed at increasing the accuracy of this technology are still a current and important topic [27]. The theoretical analysis of the geometry on the formation of connected surfaces provides basic knowledge for a better understanding of this issue and enables the application of this knowledge in a wider context.…”

The presented contribution focuses its attention on the research on the influence of the angular setting in a hobbing mill on the adjustment of the tooth profile created by this technology. The aspect of influence from the angular settings in the hobbing mill on the final shape of the gears is investigated. In this research, the effect of substituting the curvilinear profile of the cutting edges with a straight profile is analyzed, observing how this approach affects the final geometry of the gears. An important point of this research is also the comparison of different profiling methods using the hobbing mill, specifically when using a normal cut, which is perpendicular to the helix of the milling cutter, and also when cutting along the axial plane of the hobbing mill.

“…During the evaluation of surface roughness, we closely monitored the parameters Ra and Rz, which typically offer adequate information about the roughness of the surface under examination [19].…”

“…In addition to Ra and Rz, there are many other surface roughness characteristics such as Rq (the root mean square deviation of the assessed profile), Rt (the total height of the profile), Rmax (the maximum depth of roughness), and many others. Each of these characteristics provides different information about the surface roughness and may be suitable for different applications and evaluations [19].…”

The article is focused on the study of the effect of laser light with three wavelengths used in a laser profilometer for the measurement of selected roughness parameters of the shiny surface of stainless steel A304 material. The measured results were compared with the results we achieved with the reference contact roughness meter (SJ-400). The findings presented are relevant to the parameters of the experiment outlined within the article. In general, the obtained results make it possible to state that when measuring the roughness of shiny cut surfaces using non-contact laser profilometry, reflections of laser light occur. The relatively best results of measuring the parameters of the roughness of a shiny cut surface on the evaluated material (A304) were achieved by laser light with a wavelength of λ = 445 nm. In contrast, as the surface roughness of the cutting surface of the used material increased, the reflection of laser light decreased. Furthermore, we can state that the values of the roughness parameters Ra and Rz of the shiny surface measured by laser profilometry were several times higher than the values measured by the reference method. In contrast, the non-contact method of laser profilometry is not suitable for accurate measurements of the roughness parameters of shiny surfaces.

The article aims to assess the roughness of parting surfaces in the context of abrasive water jet technology for various materials. The evaluation is based on the feed speed of the cutting head, which is adjusted to achieve the desired final roughness, taking into consideration the stiffness of the material being cut. We used non-contact and contact methods to measure selected parameters of the roughness of the dividing surfaces. The study included two materials—namely, structural steel material S235JRG1 and aluminum alloy AW 5754. In addition to the above, the study involved using a cutting head with varying feed rates to achieve different surface roughness levels required by customers. The roughness parameters Ra and Rz of the cut surfaces were measured using a laser profilometer (laser profilometer). To ensure the accuracy of the laser profilometer, a control roughness measurement was conducted using a contact roughness gauge. The roughness values obtained for Ra and Rz from both measurement methods were plotted on a graph to illustrate their dependencies and were subsequently evaluated and compared. By measuring the roughness parameters Ra and Rz, the study was able to provide insights into the effectiveness of the cutting head’s feed rates in achieving the desired roughness levels. Additionally, by comparing the results of the laser profilometer and contact roughness gauge, the accuracy of the measurement non-contact method used in the study was verified.
