1 maj 2022 · Properly selected edge micro-geometry can avoid the edge fracture and slow the tool wear rate by changing the distribution of the thermomechanical loads along the cutting edge. It is known that tool wear has detrimental effect on surface quality, which in turn is influenced by the surface topography.
16 kwi 2021 · In the present study, the impact of the asymmetric edge preparation on the cemented carbide tool milling 45 steel was investigated. A simulation was performed with DEFORM software and the corresponding cutting experiment was based on the orthogonal design.
(i) Back Rake Angle: It is the angle between the face of the tool and plane parallel to its base. It is also known as front rake angle or top rake angle. (ii) Side Rake Angle: It is the angle between the face of the tool and the shank of the tool. (iii) End Clearance (Relief) Angle:
3 lis 2020 · This study presents an experimental exploration to understand the rounded cutting edge of solid carbide end mills with CrTiAlN coating on milling SUS-316L steel, and the tool performance in terms of cutting force, tool wear, and tool life is investigated.
19 kwi 2021 · This study examines and compares the performance of three state-of-the-art milling tools for high-speed end milling while cutting the same material, stainless steel. The tools have the same base material (tungsten carbide — WC-Co), with different geometrical parameters and coatings (TiAlN and AlCrN).
sharpness and cutting edge strength. This is adequate for carbon steels, some tool steels or even light finishing passes in aluminum. However, when machining stainless steels, a sharper cutting edge needs to be employed as to lessen the work-hardening effects and promote a more free cutting action. This is where a 45° helix
1 lis 2023 · Bakar, Ghani, and Che Haron studied the influence of cutting-edge preparation on milling AISI H13 steel with carbide tool. The edges were prepared with 30 μm and 50 μm edge radius. And the process was carried out in two ways: dry machining and with application of liquid nitrogen as cutting fluid.
