THEORETICAL RESEARCH REGARDING THE CUTTING PROCESS

Abstract

This paper presents a theoretical study about cutting process of vegetable products. Theoretical study is performed taking into account the following simplifying assumptions: the material is an elastic surface that has unlimited ability to deform in a transverse direction in proportion to the thickness of the blade; cut material is in constant contact with the edge and the inclined faces of the knife; the tension generated in material mass is proportional to material deformations. In order to achieve the cutting process, is necessary that between the edge of the blade and the material that is going to be cut, there must be a relative movement, with a certain speed in relation to the material being cut, the knife can execute moves in two directions: normal and cross. For the choice of shredding mechanism and hence the type of shredding machines, is necessary to take into account the request states developed by the cutting organ in the material mass.
