Abstract

Multi-purpose designed and manufactured constructions may also wear out over time, and breakage or rupture may occur as a result of this wear. In terms of cost, it is more economical to produce these parts by the welded joining method instead of reproducing them. In this context, in this study, a filler welding process was performed on DIN 1.2379 cold work tool steel materials with a welded joining process. The surfaces formed as a result of the filling process were machined by the milling method on a CNC milling machine. The investigation revealed that when cutting speed increased, surface roughness levels reduced. The opposite was observed for the cutting forces with increasing cutting speed. It was found that feed rate had the greatest impact on both cutting force and surface roughness. Regression analysis was used to create prediction equations for surface roughness and cutting force, and the outcomes of the experiments and predictions were compared.

Keywords
