EXPERIMENTAL METHODS OF RESEARCH OF THE DYNAMICS OF CUTTING DURING TURNING
Keywords:
cutting resistance force; dynamics of cutting; tangential component of cutting forceAbstract
The article deals with the factors that affect the volume of the cutting resistance forces. It is shown that experi-mental methods for studying cutting dynamics are preferable to theoretical ones, since empirical formulas, in comparison with theoretical relationships, give more accurate results. Methods for processing experimental data are considered, when used as approximating power-law dependencies of mode y = Axq. A method is presented for obtaining the general dependences of the cutting force components on the regime parameters on the basis of particular dependences which were obtained experimentally. The technique of performing laboratory work to determine the tangential component of cutting force Pz, using a one-component mechanical dynamometer is considered.
