Electromagnetic chucks are used widely in grinder, milling machine and machining center, planer and drilling machine.This article uses DOE technology to carry out the optimal design of the electromagnetic chucks. By selecting suitable design parameters and orthogonal table,which correspond to the level of each row and this series of the factor level ,the expected experiment resuits are obtained. This method is used to come to higher design performance and cost ratio of the electromagnetic chucks.%电永磁吸盘已在磨床、铣床、加工中心,以及刨床和钻床上得到广泛应用,应用DOE技术对电永磁吸盘进行优化设计,通过选择不同的设计参数,合适的试验设计方法进行试验,选用正交表来安排试验,把各列的水平和该列相应因素的具体水平对应起来,得到了预期的试验结果,实现了电永磁吸盘设计性能与成本比最高.
