Abstract: In order to achieve the accurate measurement and control of grinding force in the blade grinding process, a new measurement method of three-dimensional and orthogonal grinding force with mutual orthogonal and independent elastic elements was put forward, and a three-dimensional grinding force measurement platform of resistance strain was designed based on the high dynamic characteristics of grinding force. The performance of the measurement platform was verified through the mathematical derivation with the related formulas of material mechanics, the finite element simulation with Workbench and the actual testing experiments. The results showed that the above methods can effectively alleviate the dynamometer’s inherent contradiction between its natural frequency and sensitivity, and significantly reduce the measurement platform’s coupling degree among the grinding force measurements in different directions, which may provide technical support for achieving the real-time accurate detection of high frequency grinding force.
