Evaluation of diamond dressers and estimation of grinding performance by dressing force measurement

Equipment to measure the dressing force exerted by diamond dressers was developed and the performances of two types of diamond dresser, a single-point dresser and a multipoint rotary dresser, were examined focusing on the relationship between dressing force and grinding performance. It was found that both types of diamond dresser induce the same dressing force if their wear widths are equal and that a strong relationship exists between dressing force and grinding performance; a sharp-edged single-point diamond dresser can be used to control grinding performance with a low dressing force. The truing accuracy depends on the dresser type and a lower dressing force results in better truing accuracy.
