High speed machining of hard materials is considered to be an efficient machining technology for die and mold industry. The paper proposes an investigation on the deformation of chips generated in high speed machining of tool steel X210Cr12. An experimental research was designed and materialized, by taking into consideration a face milling process. A power type function empirical mathematical model was established in order to highlight the influence exerted by the steel hardness, milling speed, feed rate and depth of cut on the chips apparent density. Graphical representations confirmed the increase of the apparent density when the steel hardness and milling speed increase, while the increase of the feed rate and depth of cut determine a decrease of the chips apparent density.

Keywords: Face milling, high speed, chips apparent density, hardness, milling speed, feed rate, depth of cut
