Influence of Hardening Process Over Modified Heat-Treated Carbon Steel Cutting Tool Materials

In this research work, we have found that tool wear rate of the materials of high-speed steel and Titanium alloy which are having optimum composition of carbon and other constituents. Here we have expounded the distinguishing characteristics of high-speed steel and Titanium alloys in respect to the tool wear. Subsequently, we have carried out heat treatment process, where two machined specimens were kept inside the muffle furnace once it attained required temperature, it was maintained at that temperature for a certain period of time and then cooled back to room temperature, we have conducted hardness test, tool wear test. In addition to these cutting operations have performed over mild steel and aluminum workpiece.本研究发现，碳及其他组分配比最优的高速钢（high-speed steel）与钛合金（Titanium alloy）材料，其刀具磨损率具有特定规律。据此，本文阐述了高速钢与钛合金在刀具磨损方面的独有特性。随后开展了热处理工艺：将两件加工后的试样置于马弗炉（muffle furnace）中，待炉温升至设定温度后，保温一定时长，随后冷却至室温；期间同步完成了硬度测试与刀具磨损测试。此外，本研究还针对低碳钢（mild steel）与铝制工件开展了切削加工实验。
