(4)采用少切削或无切削加工的工艺方法，以提高工件强度，降低制造成本。对于齿轮加工，汽车行业中早已大量采用整体滚锻、精锻成齿的方法来减少甚至取消齿形的加工量。工程机械的驱动桥差速器齿轮现也已开始采用精锻齿轮。精锻使得金属纤维沿齿形成形方向包络，不象一般齿轮切削齿形时把金属纤维切断，精锻齿轮大大提高了齿轮的承载强度，减少了切削量，甚至可以不必再进行齿形加工，降低了制造成本。
(5)尽可能用焊接件代替一些自由锻的锻件。
(6)统一零件的热处理技术要求和工艺规范，以便可以在同一炉中对不同零件同时进行热处理，提高电炉利用率;节约电力消耗。
(7)充分利用锻件余热，在锻后继续加热，直接进行锻后正火等热处理。
(8)根据零件的具体情况，制定合理的热处理技术要求。
