ABSTRACT

Textured cutting insert filled with solid lubricants is one of the best alternative cooling methods in metal cutting industries. The problem associated with textured insert is the supply of solid lubricant and its continuity in flow while machining. In this work, an attempt is made on experimental investigation of supply methodology of solid lubricant to the textured inserts during turning process. Three different types of supply methodologies (paste form, liquid form, and soft coated form) are investigated. Performance of micro-hole textured inserts with tungsten disulfide (WS₂) solid lubricant are conducted. The effect of control factors on an average surface roughness (R_a) using different solid lubrication supply is investigated. Analysis of Variance (ANOVA) method is applied for the estimation of significance. The results of the study reveal that the soft coated solid lubricant to the textured insert is performed better than the other methodology used for supplying of solid lubricant. Supply methods of solid lubricant with micro-grooved inserts are investigated for promoting dry turning process. This work eliminates difficulty in supply mode of solid lubricant to the cutting zone. Soft coated textured inserts are noticed significant advantageous of uniform spread, additional storage, and supply.

摘要

填充固体润滑剂的纹理切削刀片是金属切削行业中最佳的替代冷却方法之一。与纹理刀片相关的问题是固体润滑剂的供应及其在加工时流动的连续性。在这项工作中，尝试在车削过程中对纹理刀片的固体润滑剂供应方法进行实验研究。研究了三种不同类型的供应方法（糊状、液体形式和软涂层形式）。进行了带有二硫化钨 (WS ₂ ) 固体润滑剂的微孔纹理刀片的性能。控制因素对平均表面粗糙度的影响 (R _a) 使用不同的固体润滑供应进行了研究。方差分析（ANOVA）方法用于估计显着性。研究结果表明，与用于提供固体润滑剂的其他方法相比，用于纹理刀片的软涂层固体润滑剂的性能更好。研究了微槽刀片固体润滑剂的供应方法，以促进干车削工艺。这项工作消除了向切削区供应固体润滑剂的困难。软涂层纹理插入件具有均匀分布、额外存储和供应的显着优势。
