Abstract: A temperature control method for additive manufacturing includes directing an energy beam of a first energy source toward a material and fusing at least a portion of the material to form a cladding layer, forging the cladding layer with a micro-forging device, and detecting a first internal effect parameter of the cladding layer at a forging position where is forged by the micro-forging device. The first internal effect parameter includes at least one of a stress or a strain of the cladding layer. The method also includes calculating a first calculated temperature of the cladding layer at the forging position based on the first internal effect parameter and adjusting the at least one of the first energy source and the micro forging device if the first calculated temperature does not fall within a desired temperature range.

Abstract: An ultrasonic roller burnishing system comprises a roller and a controller. The roller is configured to be pressed against a surface of a workpiece to a pressing depth, roll on the surface at a feed rate, and vibrate at an ultrasonic frequency under a back pressure. The roller is pressed and rolled by a motion unit which is driven by a drive motor. The vibrating of the roller is driven by an ultrasonic vibration unit with an input current inputted thereinto. The controller is configured to adjust at least one of the pressing depth, the back pressure, the input current and the feed rate based on an expected residual compressive stress and a real time output power of the drive motor, to generate a residual compressive stress in the workpiece which is in an expected range predetermined based on the expected residual compressive stress.
