The effect of coolant concentration on tool performance when machining nickel-base, C-263 alloy with triple coated (TiN/TiCN/TiN) carbide insert at various (3-9%) coolant concentrations and under different cutting speed conditions is investigated. Tool life, tool-failure modes, wear rates, component forces and surface finish generated during machining were recorded, analyzed and used to formulate mechanisms responsible for tool wear at the cutting conditions investigated. Anal. of the recorded data shows that tool performance during machining is dependent on coolant concentration 6% Coolant concentration gave the best overall performance as effective combination of cooling and lubrication functions were achieved during machining. Increasing coolant concentration to 9% reduced tool performance due to a reduction of the tool-chip contact length area and the consequent increase in compressive stresses at the tool-chip and tool-workpiece interfaces. This action often leads to pronounced chipping of the tool cutting edge during machining. Friction coefficient between the workpiece material and substrate increases once the coating layer(s) is broken as a result of the direct contact between the tool substrate and the work material. This action increases mech. wear of the tool, which in turn leads to a significant increase in the cutting force with negligible effect on the feed forces during machining. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Electric Literature of 4719-04-4
