Cited in the reference literature, empirical formula is usually acceptable for standard materials processed. When new materials have to repeat the experiments again. The article presents the analytical relationships derived from the generalization of the work of Russian and American scientists, in particular: VF Bobrov, NI Lvov, VS Kushner, a Merchant ME, Astakhov, V.P. These relationships relate the values of the components of the cutting force with time and the actual yield strength of the material being processed, making it much easier to calculate the components of the experiment of cutting force in turning based on the radius of curvature of the cutting edge and tool wear on the rear surface. Shrinkage factor chips taken approximately equal to one. Experimental verification showed acceptability found dependences for practical use, particularly important in the processing of materials of new brands.
