RELATIONSHIP BETWEEN THE VELOCITY COEFFICIENT AND MOMENT OF FORCE TO CUTTING WITH A DISC KNIFE
Abstract
A number of food products are effectively cut with disc knives with smooth cutting edge. Due to the elasticity of the food products, the deformation that arises during their dissection causes friction forces between the side walls of the knife and the product. Given these frictional forces formulas are derived for the resultant friction power and friction torque [1].
This article is a continuation of previous studies [1; 2; 3; 4]. A study is proposed on the influence of the parameter λ, representing the ratio of the cutting velocity of the disc to the feeding velocity, on the resultant friction moment.
