The single factor design of experiment on face milling of Invar36 is conducted by using coated carbide insert to characterize the influence of cutting parameters on the cutting force. The frequency spectrum analysis of the dynamic milling force, and the generation and characteristics of cutting force signal during cutting process are studied. The milling force of Invar36 is also compared with that of 0Crl8Ni9. The cutting parameters, including cutting speed, and feed and depth of cut, are taken into consideration to analyze the influence on the cutting force. The results show that radial component force in tool coordinate system reflects the extrusion between flank face and workpiece, and the peak force of tangential component is ahead of radial component force during a cutting cycle. The correlation coefficient of regression model shows that the depth of cut has the greatest significance on the cutting force followed by feed, while the cutting speed has the least influence on cutting force. And with the increase of axial cutting force, the degree and depth of grain distortion become larger. [ABSTRACT FROM AUTHOR]
