RESEARCH OF TECHNOLOGICAL FORCE OF SEPARATING OPERATIONS OF MULTILAYER MATERIALS
The results of theoretical and experimental studies of the technological force of cutting-punching of three-layer seals with a middle metal layer and surface layers of thermally expanded graphite are presented. Dependences of the process force on the thickness of the central metal layer, the diameter of the manufactured product and the taper angle of the tool are given. Satisfactory agreement between the results of theoretical and experimental studies is shown.
