As to spiral groove grinding, a formed wheel was needed to be designed and manufactured conventionally based on envelope theory, and then this wheel was used to grind the specified spiral groove. This paper tried to find the other way to manufacture the specified spiral groove with common dish wheels. A generic model for groove grinding is presented in this paper, the groove geometries can be calculated under certain grinding parameters. The relations between the grinding parameter and groove geometries were studied numerically. To manufacture the specified spiral groove with common dish wheels and no special wheel is needed to be designed. This method offers a new way for the spiral groove grinding. This technology also makes the spiral groove virtual machining possible. The technology is also a real DFM (Design For Manufacture), because the design process for spiral groove is the process for selecting manufacture parameters.
