A method of determining feed and radial forces has the steps of subdividing work materials into seven groups which are different from one another by Brinell hardness, for each group separately determining a feed force and radial force based on a tangential force in accordance with individual formula which is different from formulas for other groups, and also separately for a turning process and for a boring process. Also, a calculator is proposed which utilizes the inventive method.
