An experimental investigation is reported on the temperatures and energy partitions involved in the grinding of cemented carbide (YT30) with a vacuum brazed diamond wheel. The grinding temperature at the wheel-workpiece interface was measured using a pair of grindable foil thermocouples and the energy partition to the workpiece was evaluated by matching the analytical temperatures to the measured results. Effects of the various grinding conditions, including wheel velocity, feed rate and depth of cut, on the temperatures and the energy partition were investigated. It was determined that the wheel velocity was the most significant factor in governing the temperature relative to the depth of cut and feed rate. The maximum temperature rise at the contact zone was below 25°C in the present study. Microscopic examination of the ground surfaces and the ground detritus revealed that brittle fracture was the dominant material-removal mode. This may be one of the reasons for the low grinding temperature in grinding YT30 with a vacuum brazed diamond wheel. The energy partition values to the workpiece obtained under different grinding conditions varied from 3.3% to 20% for dry grinding YT30.

An experimental investigation is reported of the energy partition to the workpiece for grinding of steels with aluminum oxide and cubic boron nitride (CBN) abrasive wheels. The energy input to the workpiece was obtained by measuring the temperature distribution in the workpiece using an embedded thermocouple technique and matching the results with analytically computed values. It was found that 60-75 percent of the grinding energy is transported to the workpiece as heat with an aluminum oxide abrasive wheel, as compared to only about 20 percent with CBN wheels. An analysis of the results indicates that the much lower energy partition to the workpiece with CBN can be attributed to its very high thermal conductivity whereby a significant portion of the grinding heat is transported to the abrasive instead of to the workpiece. The much lower energy partition to the workpiece with CBN wheels results in much lower grinding temperatures and a greatly reduced tendency for thermal damage to the workpiece.

In order to establish a high performance grinding method of cemented carbide, the grinding force distribution on the working surface of the cup type electroplated diamond grinding wheel is experimentally analyzed with the grinding force variation of face grinding, which is carried out on the narrow workpiece. The grinding force distribution is obtained by the successive difference of the grinding force variation. The grinding state becomes steady as soon as beginning of the interference of grinding wheel in workpiece, because the edge profile of workpiece is formed as same as the envelope of the grinding wheel. Main conclusions obtained in this study are as follows. In the region of the front edge of the grinding wheel, relatively large grinding force occurs, then in the region of the rear edge of the grinding wheel, the grinding force becomes smaller. In the left right-side end of the wheel, the grinding forces are larger than the center of the wheel. It is made clear that the grinding force distribution shows the peak value near the outer part of the wheel, and the peak value is larger in the center part of the wheel, on the contrary, the peak width become broad in both the left and right-side end of the wheel.
