DEVICE FOR DETERMINING THE CUTTING RESISTANCE FORCES OF MATERIALS Russian patent published in 2023 - IPC G01N3/02 G01N3/30 G01N3/58 

FIELD: test equipment.

SUBSTANCE: invention relates to devices for determining the forces of cutting resistance as a result of single cuts of samples of the tested materials. The device comprises a base rigidly mounted on the base of the rack, a pendulum mounted pivotally through the axis on the rack, with a cutting element pivotally mounted on the pendulum. The pendulum additionally includes a pivotally mounted link pivotally connected to the rod. On one side, the force sensor is connected to the pendulum, and on the other side, through the link and the rod, it is connected to the cutting element.

EFFECT: improving the accuracy of determining the cutting resistance forces arising on the cutting element with a single cut, without taking into account the rigidity of the material, and making it possible to determine the instantaneous cutting resistance forces.
