[0008] The current three-dimensional force detection methods include a three-dimensional force detection method based on a flexible tactile sensor array, a three-dimensional force detection method based on electromagnetic induction, and a capacitive three-dimensional force detection method. At the same time, the three-dimensional force detection accuracy of the above method is generally not high, but ultra-precision machining has the characteristics of ultra-low cutting force, and there are also irreconcilable contradictions

Description
technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to a mechanical flexible mechanism capable of realizing single-axis, double-axis and three-axis force detection functions. Background technique [0002] With the development of ultra-precision technology, special fields have higher and higher requirements for the complexity of optical three-dimensional free surfaces, and the demand for high-performance manufacturing of microstructures is increasing day by day. [0003] Cutting force is an important indicator reflecting the cutting state, and real-time detection of cutting force has been widely used to identify or monitor the dynamic behavior of the cutting process and the condition of cutting tools. There are three main applications: [0004] (1) Characterize, model, and optimize the cutting process; understanding metal cutting mechanisms, such as the effect of cutting variables on cutting forces, then enables pro...
