Description

technical field [0001] The invention belongs to the field of workpiece cutting state monitoring, and in particular relates to an on-line measuring device for workpiece temperature and size change during turning. Background technique [0002] Aluminum alloy is widely used in the aerospace field because of its low material density and good processability. With the development of manufacturing technology, turning is playing an increasingly important role in the processing of precision structural parts such as aviation and aerospace. During the turning process, the cutting heat enters the workpiece to increase the temperature, the workpiece expands when heated, and the size of the workpiece undergoes non-similar deformation, which affects the machined surface morphology, quality and workpiece size pass rate. At the same time, cutting heat affects the life of the tool. During the turning process, the workpiece and the spindle are running, the contact area between the tool flank...
