“…In this study, cutting edge chipping was characterised by the roughness parameter along with the material-removal curve parameters, where Rz denotes the maximum roughness, Rp represents the mean smoothing height, and Rv indicates the mean depth. These parameters play a pivotal role in the efficacy and wear resistance assessment of cutting tools against materials, thus influencing tool longevity and the precision of machined components [4].…”

“…Roughness parameters, including Ra, Rz, Rp, Rv, and Rmax, are widely used to evaluate the wear state of the cutting edge (Fig. 1) [4] and to determine the optimal re-sharpening interval. In this study, cutting edge chipping was characterised by the roughness parameter along with the material-removal curve parameters, where Rz denotes the maximum roughness, Rp represents the mean smoothing height, and Rv indicates the mean depth.…”

Current domestic reground tool measurement methods either rely on the operator's experience or involve analyzing signals from multiple sensors to determine the tool condition. Despite the availability of numerous measurement techniques, accurately determining the condition of reground tools' condition remains challenging due to the varying time, equipment requirements, and the inherent difficulty in analyzing complex signals. Consequently, collecting comprehensive tool data becomes imperative. This study introduces a novel approach by developing a method for measuring the outer edge of tools, enabling precise condition assessment through a vision-based measurement system. This system not only aims to mitigate the errors commonly associated with manual measurements in the manufacturing sector but also seeks to enhance the process analysis efficiency. By doing so, it aims to significantly decrease the rejection rates of tool measurements and streamline the analysis process, potentially extending tool life and improving performance management. This method promises to contribute to more sustainable manufacturing practices by optimizing tool usage and reducing waste.

“…In addition, higher edge quality lessens the stress concentration between the tool and the workpiece, resulting in a uniform distribution of loads. This slows a cutting edge's wear [7], chipping formation during cutting [8], and the temperature achieved [9]. Moreover, cutting edge preparation is used to minimize compressive residual stresses, providing a smooth surface for post-coating the desired end-mills [6].…”

Precision edge preparation techniques for cemented carbides enable optimization of the geometry of tools’ cutting edges. These techniques are frequently used in high-stress environments, resulting in substantial improvements in tools’ cutting performance. This investigation examined the impact and evolution of cutting edge parameters and resulting surface finishes as a function of dry-electropolishing time on an end-mill. Findings demonstrate enlargement of the cutting edge radius, a decrease in surface roughness, and the mitigation of defects induced during previous manufacturing stages (i.e., smashed ceramic particles, burrs, chipping, etc.). Additionally, a direct correlation between dry-electropolishing time and primary cutting edges’ micro-geometry parameters has been established.

“…The controlled shape of the edges will improve reliability and control the cutting process at various stages. In addition, the grinding processes themselves are prone to poorly controlled changes in edge shape [50]. Therefore, an important aspect of the development of a computer-aided design of end mills for high-speed machining is flute profiling taking into account the radius of the cutting edge, the value of which can change stochastically under various technological conditions [51,52].…”

In designing a conical end mill with a helical front surface, the geometry of the grinding wheel has an influence on the shape of the back profile, as this study shows. For the first time, the influence of the generix of a conical circle's angle of inclination on various interference schemes has been studied. Through the combination of laser ablation and grinding, the underpoints of the helical surface were given their final shapes, indicating the standard sizes that would affect the execution's ability to be manufactured. This work will result in the engineering of a system for automated manufacturing of conical mills, as well as the development of control programs for CNC grinding and laser ablation machines. It will also enable the development of design support for cutting tool production. The work reveals analytical dependences of the value of the clearance angle, controlled at the point of the flank surface during the transition from the radius of the cutting edge to the profile section of the helical flute in the radial section, which is set from the coordinate of a parametrically defined point along the OX axis in the radial section. It has been established that the value of the radius of curvature of the cutting edge and the point of formation of the transition of the radius to the profile can significantly change the kinematic geometry of the cutter (up to nine degrees when the radius of the cutting-edge changes by 30 μmm).
