“…The size of radius on the cutting edge is linked to the observed damage in the related location and a numerical grading is proposed to describe the level of sharpness. Other systems for definition of edge wear and profilometry include metallographic cross-sectioning, blade cross-sectioning and use of surface scanning [42][43][44], SEM [45,46] AFM, as well as edge replication, mass changing and optical microscopy [47][48][49].…”

“…Consequently, a geometrical surface structure analysis of gear tooth flanks requires the use of the two functions. The height parameters of surface topography are very helpful for predicting the use of the surfaces, which are totally separated from each other with an oil film, for hydrodynamic lubrication [32,33,35,36]. In the case of dry and mixed lubrication, due to lack of straight relations between GPS features and tribological functions [34,35,36].…”

In the case of dry and mixed lubrication, due to lack of straight relations between GPS features and tribological functions [34,35,36]. The GPS correctness of the gear tooth flanks is evaluated by means of height, curvature, density of peaks or summits [31,34], slope [36,37,38,39,40,41] or plasticity index [31,34].…”

The paper presents the methodology of modelling tooth flanks of cylindrical gears in the CAD environment. The modelling consists in a computer simulation of gear generation. A model of tooth flanks is an envelope curve of a family of envelopes that originate from the rolling motion of a solid tool model in relation to a solid model of the cylindrical gear. The surface stereometry and topography of the tooth flanks, hobbed and chiselled by Fellows method, are compared to their numerical models Metrological measurements of the real gears were carried out using a coordinated measuring machine and a two -and a three-dimensional profilometer. A computer simulation of the gear generation was performed in the Mechanical Desktop environment.

“…Van Woerden [23] used the diffraction of the laser light which was pointed at the knife tip and vision detection of the light intensity levels measured at various angles to determine the sharpness of the knife. Lu et al [24] proposed the hybrid type instrument which is capable of both contact and non-contact measurement by using optical displacement sensor. In this paper, it was proved that the resolution of non-contact method was two times better than the contact one.…”

Vacuum conveyor belt punching process by using the piercing punch which cooperates with the die has potential to be modified in aspects of lowering the perforation force, extending the tool life, and improving the hole quality in the perforated belts. All these parameters have an influence on the efficiency of the process and strictly depends on the punch geometry. This indicates that based on these criteria the optimization of the tool constructional features may be performed. In the presented research, authors have shown the linear correlation between the resistance force of the compressed material of the multilayer polymer composite belt in punching and the efficiency of the process. It was also proved that using the effective geometry of the piercing punch with spherical bowl can reduce the perforation force by 69%. Based on the obtained model, the simplified optimization as well as the evaluation of the punches with defined geometry can be performed, since all characteristics of the material compressive force obtained for the effective punches were almost consistent. For proper analysis, it is necessary to use the combination of the analytical and numerical modelling, computer simulations with using the finite element method (FEM) and the experimental tests. However, by performing simple compression tests for various tool geometry on the strength testing machine, it is possible to perform the comparison analysis of different piercing punches based on the derived models. This approach can be used to evaluate the properties of selected tools for the groups of materials with wide divergence of the mechanical properties without performing the complex research.
