A Sustainable Approach for Milling of Duplex Stainless Steel by Increasing the Cutting Tool Utilization

Summary, in English

Common practice in industry is to rotate the milling cutter in only one direction even though the geometry of the inserts are thus that they could be used again while the milling cutter is rotating in the opposite direction. The aim of this study was to investigate to what extent it is possible to increase the tool utilization during milling by first rotating the milling cutter in one direction until the inserts were considered as worn out according to the conventional standard. Afterwards the inserts where used in another milling head which rotated in the opposite direction. The experiments were conducted while milling duplex stainless steel SAF 2304. This due to that machining of duplex stainless steel is often thought of as leading to adhesive wear of the cutting tool which added an important type of tool wear to the investigation in addition to the dominating abrasive wear. The experimental results show that by rotating the milling cutter in both directions it was possible to increase the tool utilization with approximately 80 %.
