Abstract: Cutting force experiments in turning aluminum-silicon alloy were carried out with cement carbide tool YG8. Experimental formulae of cutting force, back force and feed force were determined based on multi-variable linear regression analysis, and they were verified by analysis of variance, the results showed that the regressed models could be used to predict cutting force under certain conditions.

Abstract: In the present paper, the effects of the hardness, strength, chemical composition, microstructure, fracture properties of the material and other factors on the chips formation and deformation were studied during cutting the brittle metal. The process of cutting the brittle metal and the basic theory of the scrap fracture was also discussed comprehensively. In addition, this study pointed out the importance of the hot working process to avoid some metallographic organizations within the cast iron such as the stripy-like and inhomogeneous graphite.

Abstract: Cutting force experiments in turning aluminum-silicon alloy ZL104 are carried out with cement carbide tool YG8. The influence of cutting parameters on cutting force is obtained based on single factor experiments. The results indicate that depth of cut and feed rate have great influence on cutting force while cutting speed provides just little impact.
