Abstract. The interaction of milk thistle seed with grooved working surfaces is revealed. The dependences of curvature of the ellipse of contact on the step between grooves and pressure distribution on the area of contact of normal force of compression are identified. The achieved dependences make it possible to justify optimal geometrical parameters of grooved working surfaces required for peeling milk thistle seed coat.

Key words: seeds of milk thistle grooved working surface, area of contact.
