Performance analysis of centrifugal-cast single-point cutting-tools developed from scrapped tools

Single-point cutting tools were developed adopting a novel technique involving centrifugal casting using scrapped and discarded tools without any compositional adjustments. These tools included single-point cutting tools, drills, milling cutters, etc., and were melted in an induction furnace and cast in a vertical rotating mold. Single-point cutting tools were developed from these cast bars. The cutting ability of these developed tools was compared with that of conventional high-speed steel (HSS) tools that were procured from the market, for cutting of mild steel (A36) workpiece under identical tool geometry and cutting parameters. The cutting ability of the conventional HSS tool and the developed tool was observed to be comparable in terms of tool wear. Further, the surface-finish, force required for cutting and chip-configuration were more or less identical. The performance of the developed tool is comparable with the conventional cast HSS tool within the cutting velocity of 52.77 m/min and yields the most encouraging results, putting these tools at par with those available in the market. Thus, the novel technique adopted is claimed to be a viable method for developing single-point cutting tools without going for stringent methods of compositional adjustments and the costly forging methods for compaction.

Automated summary

Single-point cutting tools were developed using a novel technique of centrifugal casting with scrapped tools, showing comparable cutting ability to traditional high-speed steel tools when cutting mild steel workpieces. The cost-effective method yielded tools with similar performance to those available in the market. The centrifugal casting process presents a viable alternative for developing single-point cutting tools.
