Experimental investigation on removing cutting fluid from turning of Inconel 725 with coated carbide tools

The aim of this study is to investigate the feasibility of removing cutting fluids from turning process of Inconel 725. For this purpose, the effects of machining parameters such as cutting speed, feed rate and depth of cut on machining forces were investigated. These forces include feed force, thrust force and cutting force. In addition, surface roughness was examined in both conditions of dry machining with coated tool and wet machining with uncoated tool. Results showed that in contrast with conventional machining processes, cutting speed and coating of tool are the most important parameters in removing cutting fluids. The data obtained from the tests indicated that in machining with coated tool with special ranges of parameters, cutting fluid could be completely removed from machining process. Furthermore, for both of dry and wet machining, the optimum ranges of parameters were presented in order to reach a green manufacturing process.
