Abstract

Analysis of kinematic parameters of book block cutting shows, that by using eccentric circular cutting knife the cutting process may be realized in two different modes: continuous cutting – with the constant contact between cutting edge and cut material, and intermittent cutting process – with the impulse cutting knife action to treated material which is book block. The paper describes the trajectory of circular knife blade movement in book cutting process. It was found that the greatest influence on the length of the road of the knife blade going through in the paper are: feed rate of the book, distance between the block and the knife rotation axis, knife rotation speed and others. The calculations allow selecting of the kinematic parameters of the cutting process, taking into account the road of knife blade inside the paper of the book during cutting with the circular knife, in order to minimize the blade wear.
