The continuous generating grinding (CGG) is an essential finishing process to manufacture gears with excellent accuracy and efficiency. However, a large amount of heat is generated during grinding, which consumes a considerable amount of electric power for the coolant supply. Although dry grinding has attracted significant attention in recent years, the basic mechanism of heat generation for this process is not well understood. Thus, the prospects of dry CGG have been quite limited. In this study, the authors unraveled the heat generation mechanism of the dry CGG by measuring the on-site temperature in the grinding area, in addition to conducting simulations and estimating the specific removal rate and the specific grinding energy. As a result of the measurement, the entire temperature history was obtained, and a clear dependence of the measured temperature on the infeed was observed. In addition, the specific removal rate was calculated to be 2–3 mm³/mms, and the specific grinding energy was calculated to be more than 100 J/mm³. It was indicated that the specific energy could be further reduced, as a large fraction of the heat was generated by friction and not by shearing. It was revealed to be important to properly determine the pitch of the grinding wheel as well as to suppress clogging by chips and to set proper dress intervals, for realizing dry CGG with high material removal rate.

连续生成磨削（CGG）是精加工和精加工齿轮的必不可少的工序。但是，在研磨过程中产生大量的热量，这消耗了大量的电力用于冷却剂供应。尽管近年来干磨引起了人们的极大关注，但是对于该过程中产生热量的基本机理还没有很好的了解。因此，干CGG的前景非常有限。在这项研究中，除了进行模拟并估算比去除率和比研磨能量外，作者还通过测量研磨区域的现场温度来阐明干式CGG的发热机理。测量的结果是获得了整个温度历史，并且观察到测量温度对进料的明显依赖性。此外，比去除率经计算为2–3 mm³ / mms，并且比磨削能量经计算大于100J / mm ³。结果表明，比能可以进一步降低，因为大部分热量是通过摩擦而不是剪切产生的。为了实现高材料去除率的干燥CGG，揭示出适当地确定砂轮的螺距以及抑制切屑的堵塞并设定适当的修整间隔是重要的。
