A method for temperature field of high-energy beam of additive manufacturing active control system and control method

The present invention discloses an active control of the temperature field gradient system and control method, the system temperature field monitoring system, heating system and a control system; a system for monitoring the temperature field information measuring temperature field shaping region around the XOY plane and obtain back to the control system, heating system on the bottom and sides forming cylinder based on a control instruction temperature field information quantized temperature field of partition independent real-time adjustment, to achieve a temperature field constant throughout the processing region of the processing, to ensure machined zone unprocessed area at a reasonable temperature gradient, to avoid warpage due to thermal stress member, deformation, cracking. While the present invention has been formed on the member directly or stress relief annealing processing directly to stress treatment, an effective solution to the forming process prone to deformation, warping, cracking and other problems, which saves time and saves energy, but also effectively shorten the time occupied by equipment, improve equipment utilization.
