Evaluation of cutting forces in granite treated with microwaves on the basis of multiple linear regression analysis

The current study is focused on the evaluation of cutting forces in granite treated with high-power (24 kW) microwave radiation based on a multiple regression analysis. As a result, dependencies of forces acting on a conical cutting pick on the irradiation time (up to 45 s), the spacing between cuts and the distance from the treated surface (in depth) were established. The values of obtained correlation coefficients are in the range from 0.90 to...
