Cemented carbide, a metal made from sintered metal carbide powder, is used mainly in forging dies. To meet customers’ needs, which are becoming more stringent year by year, these dies must be machined with high precision. In this study, we evaluated machining quality from various data obtained during the cemented carbide grinding process, hoping that this might help us to reduce costs by performing high-precision machining without rework. We therefore undertook a study of methods of evaluating machining conditions. We tried evaluating machining quality by evaluating roundness, integrated machining power consumption, and machined weight. The SN ratio results obtained from roundness evaluation and power evaluation lacked reproducibility, and the precise additivity of their effects could not be confirmed. We did, however, find general agreement and consistency in the sensitivity of power evaluation. We also found that by comparing simultaneously measured vibration data and power data, it might be possible to follow the machining status in real time, while the process was being monitored.
