The cutting forces on obique cutting with single cutting edge are investigated analytically, based on the thin shear zone model. To predict the three components of oblique cutting forces analytically, an experimental data of orthogonal cutting and cutting energy method are used. And the predicted results are in good agreement with the experimental results under the equivalent cutting conditions. The results obtained in this study are summerized as follows, 1.The cutting forces of the oblique cutting can be predicted analytically by applying energy method even if only orthogonal cutting data are in hand. 2.The analytical prediction of cutting forces on oblique cutting with single cutting edge is applicable to the double cutting edge model.

The feasibility of application of the rotary carbide tools in the machining of aluminium alloys is studied in this paper. For the experiment, a new rotary tool holder has been designed and manufactured. Experiments were performed using Taguchi methods and regression analysis to analyse the influence of various factors and their interactions on the cutting characteristics of rotary carbide tools during machining. It turns out that the inclination angle has the greatest influence on the cutting force and the depth of cut has a clear effect on the surface roughness. The cutting force and surface roughness can be estimated using an equation proposed in this paper, which will be well matched to the data of physical experiments.
