在任何磨削操作中，在砂轮与工件接触期间，热量周期性地流入砂轮表面的磨粒中，并且在砂轮的单次旋转的剩余部分期间被提取。如果可以假设在单个砂轮旋转的冷却部分期间向内流动的所有热量都被向外提取，则可以容易地估计热分配系数R =热功/总磨削能量。本文讨论的条件下，这一假设是一个可接受的近似。
In any grinding operation heat flows periodically into the abrasive grains in the surface of the wheel during wheel-work contact and is extracted during the remaining portion of a single revolution of the wheel. If it can be assumed that all of the heat flowing inward is extracted outward during the cooling portion of a single wheel revolution, then the thermal partition coefficient R = heat to work/total grinding energy may be readily estimated. This paper discusses conditions under which this assumption represents an acceptable approximation.
