Abstract

The invention relates to the technical field of metal powder processing, in particular to a production control method for hard alloy additive materials. The method comprises the steps that firstly, laser power and powder feeding speed are collected in the hard alloy additive machining process; process difference parameters are determined according to the matching difference and the feature consistency of the laser power and the powder feeding speed; comparing process difference parameters of each processing layer and other processing layers, and screening out a comparison layer of each processing layer; and determining a process control influence coefficient of each processing layer by combining the matching difference and process difference parameters of the laser power and the powder feeding speed between the processing layer and the corresponding comparison layer, correcting feedback errors of the laser power and the powder feeding speed collected by the PID controller, and determining the powder feeding speed of the processing layer according to the corrected feedback errors. And the laser power in the hard alloy additive machining process and the powder feeding speed when the metal powder is added are controlled. According to the method, the control accuracy of the production process of the hard alloy additive is improved.
