Abstract

The invention discloses a high-speed cutting deformation field transient measurement device and an application method thereof. According to the technical scheme, the device comprises a high-speed cutting loading unit, a cutting root microscopic image high-speed acquisition unit and an image digital processing unit, wherein the high-speed cutting loading unit is used for realizing high-speed orthogonal cutting loading and recovery; the cutting root microscopic image high-speed acquisition unit is used for continuously capturing cutting root microscopic images at real time during the cutting process; and the image digital processing unit is used for processing a series of high-speed cutting transient images obtained by shooting so as to obtain a cutting root deformation field during the high-speed cutting process. By additionally arranging the cutting root microscopic image high-speed acquisition unit and the image digital processing unit, non-contact measurement of the high-speed cutting transient deformation field can be realized, and the measuring process is safe and reliable. Through a laser velocity measurement signal triggering a high-speed special camera to shoot, synchronization of cutting process and shooting process can be realized. By arranging an optical enlargement device between the high-speed special camera and a workpiece, microscopic images of cutting roots can be captured more clearly, thus being helpful for raising subsequent image processing precision.
