Description

technical field

[0001] The invention relates to the field of heat measuring equipment, in particular to the improvement of a tool deformation energy measuring device. Background technique

[0002] The problem of tool deformation and temperature rise has become a research hotspot in the field of aerospace manufacturing in recent years. In the metal cutting process, the force-thermal effect causes the deformation of the tool, which increases the wear of the tool, shortens the life of the tool, and seriously reduces the machining accuracy of precision parts. In order to study the force-heat effect of the cutting system and establish an accurate thermal-mechanical coupling error model, it is necessary to determine the source of heat generation. In the processing system, the bending and torsional potential energy of the tool is usually converted into heat in the form of friction or vibration, which causes the temperature of the tool to rise, resulting in machining errors. In th...
