The Influence of High-Speed Milling Strategies on 3D Surface Roughness Parameters

Nowadays in die-cast manufacturing high speed milling are used to increase quality, accuracy and speed of material processing, also to reduce processing costs and save machining time. This paper is devoted for research of high-speed processing regimes impacts and their effect on the surface roughness quality of the machined material and 3D surface parameter values. This paper contains recommendations for die-cast manufacturers, deploying HSM, to improve machining process and obtain required surface quality. Analysis of variance methodology is used in this research. Research identify the most appropriate HSM regimes, that most important is chosen material type or material mechanical properties, influencing kurtosis of the scale-limited surface (Sku) and height of the bearing area ratio curve (Stp). Feed rate is most significant for texture aspect ratio (Str) and strategy type – influencing parameter of arithmetic mean surface height (Sa) and valley fluid retention index (Svi)
