Abstract

The invention discloses a high-accuracy high-speed micro-cutting three-dimensional dynamic force testing platform. The high-accuracy high-speed micro-cutting three-dimensional dynamic force testing platform comprises a supporting and positioning base, an electromagnetic force to-be-machined platform, a pair of high-rigidity elastic thick-wall elements and a high-rigidity thin-wall hollowed elastic element. The high-rigidity elastic thick-wall elements are installed on the supporting and positioning base. The high-rigidity thin-wall hollowed elastic element is installed between the high-rigidity elastic thick-wall elements. The electromagnetic force to-be-machined platform is installed above the high-rigidity elastic thick-wall elements. Strain gages evenly distributed circumferentially are arranged in the middle of the high-rigidity thin-wall hollowed elastic element. An elastic element in the middle is a whole formed by three parts, structurally-optimized hollowing-out treatment is conducted on the high-rigidity thin-wall hollowed elastic element, and the size and the mass are reduced by half on the premise that rigidity and inherent frequency are guaranteed. Compared with a traditional testing platform, though the inherent frequency of the traditional testing platform is improved, the displacement of the elastic element is reduced as a whole, and therefore the overall sensitivity is affected.

Description

technical field [0001] The invention relates to a high-precision and high-speed micro-cutting three-dimensional dynamic force testing platform, which belongs to the precise measurement of three-dimensional dynamic force under the high-speed micro-cutting environment. Background technique [0002] At present, high-speed micro-cutting technology is one of the hot spots of modern manufacturing technology, and the dynamic force measurement of micro-cutting has become an important part of micro-cutting technology. Accurate measurement of cutting force signals under micro-cutting is an important guarantee for the study of micro-cutting deformation and cutting friction, and is a necessary link to manufacture good workpieces for research. With the improvement of high-speed micro-cutting requirements, accurate measurement of cutting force is extremely important. However, the force measuring platforms currently used in China are all imported products, with high cost and relatively la...
