Calculation of cutting force by book-edge trimming with disk knives

Abstract

The paper proposes formulas for theoretical calculation of forces when trimming book-edges with a disc knife. The theoretical model is based on experimental data obtained by the authors. The authors calculated the approximation parameters from own experimental studies. The kinematic parameters of the cutting process and the approximated value of the unit cutting force were used in the calculation formulas. Calculation makes it possible to predict value of total cutting force depending on diameter and sharpening angle of knife, value and direction of its angular speed, feed rate, thickness and distance of book block from axis of knife rotation.
