With the partial least squares(PLS)algorithm,the optimization of the processperameters and prescription data of sintered Nd-Fe-B permanent magnets,colle-cted from a factory, is demonstrated in this paper. The project includes decreasingthe temperature and humidity of the environment during the rough smash process,slowing down the speed of the class wheel, lessening the ratio of Nd and B,andadding some Ti,etc. The conclusions have been corroborated by experiments anddocuments They are reasonable and of practical significance.
