Form grinding of gears using an aluminum-oxide grinding wheel easily dressed by a single-point diamond dresser has lately attracted considerable attention as a major gear-grinding method In the future because of Its flexibility and productivity. In this lnvestigation, the optimum condition of wheel-dressing and gear-grinding to obtain the larger grinding length without grinding burns which may occur on ground tooth surfaces Is Investigated. The case-hardened test gears were finished using the aluminum-oxide grinding wheels(WA46K, WA60J and WA80J)with the grinding fluid of a solution type on the trial-made NC gear grinder. The obtained main results are as follows.(1) The grinding efficiency of form grinding of gears Is equivalent or superior to that of a conventional gear-grinding method. Its grinding efficiency Is limited by grinding burns which occur on ground tooth surfaces.(2) The higher feed rate of the work In form grinding makes hard to Induce grinding burns when the metal removal rate expressed by the product of an amount of the infeed by the feed rate Is equal.(3) In form grinding of gears, the dressing condition of the grinding wheel affects remarkably the grinding length without burns. The low wheel speed and the high feed rate of a dresser In wheel dressing Increase the grinding length without burns. Especially, the former Is quite effective In the Increase In grinding efficiency because of the creation of the sharp cutting-edges and large chip-pockets on the wheel surfaces.(4) Under the same grinding condition, the grinding power when grinding burns occur Is almost constant regardless of the dressing condition of the grinding wheel.(5) To predict the occurrence of grinding burns by watching the changes In grinding power, the equation which expresses the relation between the grinding condition and the grinding power when grinding burns occur was derived experimentally.

用氧化铝砂轮成形磨削齿轮，由于其灵活性和生产率，最近已成为一种主要的齿轮磨削方法，并引起了人们的广泛关注。本文研究了砂轮修整和磨齿的最佳条件，以获得较大的磨削长度，而不产生磨削烧伤。在试制的数控磨齿机上，用WA46K、WA60J和WA80J三种氧化铝砂轮，采用溶液型磨削液，精磨了硬齿面试验齿轮。得到的主要结果如下。(1)成形磨齿的磨削效率相当于或上级常规磨齿法。它的磨削效率受到磨削齿面上产生的磨削烧伤的限制。(2)成形磨削时工件进给量大，不易引起磨削烧伤。当进给量与进给量的乘积所表示的金属去除率相等时。(3)在成形磨齿中，砂轮修整条件对无烧伤磨削长度有显著影响。在砂轮修整中，砂轮速度低，梳妆台进给速度高，可增加磨削长度而不烧伤。特别是前者，由于在砂轮表面上产生锋利的切削刃和大的容屑槽，在提高磨削效率方面非常有效。(4)在相同的磨削条件下，无论砂轮修整条件如何，发生磨削烧伤时的磨削功率几乎不变。(5)为了通过观察磨削功率的变化来预测磨削烧伤的发生，通过实验推导出了磨削烧伤发生时磨削条件与磨削功率的关系式。
