磨削是最重要的制造工艺之一，特别是当必须实现高表面质量或必须加工硬或脆材料时。由于接触区的高热负荷，磨削性能常常受到工件失效的限制。因此，经常使用结构化或花纹砂轮来降低接触区的热负荷。本文将介绍一种利用飞切运动学进行构图的新构图方法。在端面磨削实验中，花纹砂轮通过显着降低工艺作用力和磨削烧伤，显示出极大的潜力来提高整体磨削性能。接触区热负荷的降低可以通过改善通过接触区的冷却液流动来解释，这是通过专门设计的冷却剂收集仓来测量的。(C)2014年CIRP。
Grinding is one of the most important manufacturing processes, especially when high surface qualities have to be realized or if hard or brittle materials have to be machined. Often the grinding performance is limited by workpiece failure due to a high thermal load in the contact zone. Therefore structured or patterned grinding wheels are frequently used to reduce the thermal load in the contact zone. In this paper a new patterning method will be introduced by using a fly-cutting kinematic for the structuring process. In face grinding experiments the patterned grinding wheels showed great potential to enhance the overall grinding performance by significantly decreasing process forces and grinding burn. The reduction of the thermal load in the contact zone can be explained by an improved coolant flow through the contact zone, which was measured with a specially designed coolant collecting bin.
