The purpose of the investigation is to propose an innovative method of single point cutting tool development adopting centrifugal casting operations. Scrapped cutting tools are melted, cast into cylindrical bars adopting centrifugal casting method, machined for developing single point cutting tools, and heat-treated for the conduct of cutting operations. Adopting Taguchi optimisation technique and considering the-smaller-the better approach, optimisation of cutting parameters viz, cutting velocity, depth of cut and feed rate for minimum surface roughness and cutting force are attempted during dry turning of mild steel (A36). Evaluation of the effect of cutting parameters on the output such as the surface roughness and the cutting force is done by using ANOVA software. The above mention studies are also repeated with the HSS cutting tool available in the market (HSS M2). The cutting ability of both tools on the basis of cutting parameters, as mentioned above is found to be at par. Also, analysis of wear characteristics yielded almost similar results. The study verifies the centrifugal casting method as a viable method for the development of single point cutting tools using scrapped tools.

优化工艺参数下离心铸造高速钢刀具切削能力研究

调查的目的是提出一种采用离心铸造操作的单点切削刀具开发的创新方法。将废弃刀具熔化，采用离心铸造法铸造成圆柱形棒材，加工开发单点刀具，并进行热处理以进行切削操作。采用田口优化技术并考虑越小越好的方法，在低碳钢 (A36) 干车削过程中尝试优化切削参数，即切削速度、切削深度和进给速度，以实现最小表面粗糙度和切削力。使用方差分析软件评估切削参数对输出的影响，例如表面粗糙度和切削力。上述研究也对市场上可用的 HSS 刀具 (HSS M2) 进行了重复。如上所述，两种刀具在切削参数的基础上的切削能力相当。此外，磨损特性的分析产生了几乎相似的结果。该研究验证了离心铸造方法是一种使用报废刀具开发单点切削刀具的可行方法。
