The definition of the knife force in cutting with a rolling blade in the chopper with a horizontal rotating disc

The article presents the studies of tuber and horizontal knife interaction in the designed chopper of tuberous roots. According to analytical reasoning, theo- retical dependencies are obtained, on which by using constructive and technologi-cal parameters of the investigated chipper roots, you can determine the cutting force, as well as to build an optimal profile of the cutting edge of the horizontal knife. On the basis of the derived dependence graphs and their analysis are made.
