A method for control of hydraulic executive device of machine tool includes displacement of tracking point along the contour of guide plate, transfer of positive or negative electric signal to electro-mechanical converter, displacement of jet pipe under effect of converter to the right or to the left, change of pressure of working liquid in end chambers of slide, displacement of slide from neutral position, supply of working liquid under pressure to one of cavities of hydro-cylinder and displacement of shape-generating point of instrument by copied contour. An electronic contour of article is used as guide plate with simultaneous comparison of deflection of shape-generating point of instrument from given parameters of the guide plate by electronic copying by means of tactile sensor. |
