Description

technical field [0001] The invention relates to a scratch test machine, in particular to a macro-micro coupling trochoidal micro-nano scratch test machine based on a flexible mechanism, which belongs to the field of micro-nano processing and manufacturing. Background technique [0002] With the development of high-end technologies such as aerospace, biomedicine, and national defense equipment, ultra-precision machining technology is more focused on high-precision, non-damaging surface preparation. However, traditional ultra-precision machining technologies, such as ultra-precision grinding, milling, etc., are difficult to clearly and accurately grasp the influence of their process parameters on the precision and damage of parts due to their extremely complex machining processes. As a key means of material characterization, micro-nano scratching technology plays a key role in the mechanical properties and processing properties of materials; with the emergence of atomic force ...
