Description

technical field [0001] The invention relates to the technical field of machining, in particular to an electric heating assisted milling device and method. Background technique [0002] The conventional conductive heating cutting technology is to pass low voltage and high current between the workpiece and the tool. During the cutting process, a contact resistance is generated between the workpiece and the tool, and a large amount of Joule heat is rapidly generated. The high temperature reduces the strength and hardness of the deformed material. Therefore, the electric heating assisted cutting technology can reduce the cutting force and torque, reduce the wear of the material on the tool, and improve the tool life. [0003] Foreign scholars have conducted experimental research on conductive heating cutting of high-temperature alloys, hardened steel and other difficult-to-machine metal materials, proving the advantages of electric heating cutting, which can reduce tool wear whi...
