【摘要】 介绍引进机型ＡＴ２５型柴油机凸轮实际轮廓的计算过程，给出了理论轮廓数值表。由于该型机凸轮加工工艺复杂、质量要求高，因此，可采用电火花线切割特种加工工艺，以提高凸轮质量。在引进机型的国产化工作中有一定参考价值。更多还原

【Abstract】 This paper gives the course of calculation for the real outline of the cam in the introduced AT25 diesel engine,and gives numerical list for the theoretical outline as well.The special technique of processing by electrospark linear excision is adopted to such a complicated processing for the cam in order to improve the quality,which can be reference to some certain introduced type of machinery during its being made in our country.更多还原
