Abstract
CVD rotary dressers are commonly used in the grinding process to dress wheels. To ensure the accuracy in profile of the dressed wheel, the CVD rotary dresser must achieve micron-level accuracy. However, CVD diamond is hard and brittle, making it difficult to achieve high-accuracy machining. In light of this, a graded grinding method is proposed in this paper to achieve precision machining of the CVD rotary dresser. The normal residual error is determined by measuring the distance between the actual profile curve and the target profile curve. Then, graded grinding is performed according to the normal residual error. In the grinding process, it is proposed that the grinding path can be planned according to the real-time profile of the grinding wheel. As revealed by the experiments conducted on a CVD rotary dresser for the NILES ZP 12 gear grinder, the profile accuracy (peak to valley, PV) of the CVD rotary dresser is improved from 14.79 to 1.57 \(\mu \)m after grinding. The fluctuation of the arc radii of CVD diamonds in different phases along the circumference is reduced from 11.7 to 1.9 \(\mu \)m.
