The effect of milling parameters and thermal modification

Milling is the machining of material with a rotating tool (milling head and milling cutter) in order to remove material. The material is milled to obtain a high-quality surface as well as exact dimensions of the workpiece, which is important for further processing (rotary, planar, or shaped surfaces) (Welzbacher et al. 2011; Kvietkov 2015).
