Investigation of the Pivoting Friction of ShKh15 Steel over R6M5 and 10R6M5-MP Steel with the Use of Mathematical Modeling

摘要

The pivoting friction of ShKh15 steel over the flat surface of a prism made of R6M5 and 10R6M5-MP steel was investigated. It was proved that, in the steady wearing mode, the pivoting friction moment is steady as well. It was shown that the change in the pivoting friction moment from the load for R6M5 steel does not stay within the boundaries of one linear dependence and for the powder steel 10R6M5-MP is linear. Wear of a ball made of ShKh15 steel in the case of friction by 10R6M5-MP steel is more intense as compared with the friction by R6M5 steel, and the friction moment, on the contrary, has a smaller value. As a result, cutters made of 10R6M5-MP steel will be more effective and energy saving during cutting of ShKh15 steel.
