The automotive industry encounters daily challenges as it navigates through new design trends and technological developments, which drive companies to rapidly develop models. This scenario paves the way for manufacturing approaches such additive (AM) is transforming by enabling production of complex geometries while minimizing material usage. Regarding cutting tools sector, AM enables resource-efficient generation shapes features that are not possible with conventional subtractive processes. work explores feasibility AM, specifically Laser Powder Bed Fusion (LPBF), in creation a milling tool geometry enhanced machining efficiency increased durability applications. final developed incorporates internal conformal channels, high teeth number (relatively size) within hollow interchangeable body. combination (post-AM) brazed PCD (PolyCrystalline Diamond) inserts, hardest available, tribological conditions at zone (improved cooling lubrication edge) expected promote ideal conditions, therefore extending lifespan, particularly relevant industry, where lightweight dictates usage metals aluminium. remarkable aluminium makes them an choice active produced bodies. typical relative small series tooling (as compared parts produced) supports turn boosts cost effectiveness these tools. demand increasing accelerates towards light weighting electrification, creating favorable opportunity implementation industry.
