High speed cutting is an important aspect of advanced manufacturing technology introduced to achieve high productivity and to save machining cost. The combination of high speed cutting and dry/wet cutting for difficult-to-cut aerospace materials is the growing challenge to deal with the economic aspects of machining. In the machining of aeronautical materials, classified as difficult-to-machine materials, the role of lubricant during the machining operations is very important. In this paper, attention is focused on Inconel 718 and concerning machining of this material under wet condition. A series of experiments are conducted by varying the process parameters and their special effect on tool wear is calculated. The experimental results indicate that the cutting speed is the most significant factor to the overall performance. The correlation between cutting speed and feed with the tool wear is obtained by multi-variable linear regression and is compared with the experimental results.

Abstract


High speed cutting is an important aspect of advanced manufacturing technology introduced to achieve high productivity and to save machining cost. The combination of high speed cutting and dry/wet cutting for difficult-to-cut aerospace materials is the growing challenge to deal with the economic aspects of machining. In the machining of aeronautical materials, classified as difficult-to-machine materials, the role of lubricant during the machining operations is very important. In this paper, attention is focused on Inconel 718 and concerning machining of this material under wet condition. A series of experiments are conducted by varying the process parameters and their special effect on tool wear is calculated. The experimental results indicate that the cutting speed is the most significant factor to the overall performance. The correlation between cutting speed and feed with the tool wear is obtained by multi-variable linear regression and is compared with the experimental results.
