According to the measuring device, a small-sized measuring system is arranged on the cutter connecting rod rotating at a high speed, so that high-speed dynamic measurement is converted into quasi-state measurement, and the advantages of freeness from contact, high accuracy, high vibration resistance and the like are achieved.

Description

technical field [0001] The invention relates to a face milling tool end face deformation measuring device based on a double pulse laser, specifically, a face milling tool composed of a spindle box, an electric spindle, a double pulse laser, a face milling cutter disc, etc. end-face deformation measuring device. Background technique [0002] High-speed cutting technology is becoming the mainstream of cutting processing. In the process of high-speed cutting, tool stress distribution directly affects the reliability and cutting performance of the tool. When cutting at high speed, the main form of tool damage of face milling cutter is breakage. The main cause of tool damage is the result of various stresses such as mechanical stress and thermal stress. Under different cutting conditions, mechanical stress and thermal stress are mutually dominant to cause damage to cutting tools. Due to the limitation of measurement methods and measuring instruments, there are few researches on...
