Forming grinding process is a crucial method for grinding the helical flute of end mills, and the calculation of the grinding wheel profile is the key to ensure the precision of the helical flute, which is constrained by grinding wheel posture and helical flute profile. However, the current calculation method has not done enough research on the estimation of the feasibility and validity of the grinding wheel profile, which could lead to contradiction between theoretical calculations and practical application. In this paper, an optimized calculation method of the grinding wheel profile for the helical flute forming grinding is proposed, which includes the calculation, analysis and optimization process. Firstly, the parameters of the helical cutting edge and the flute surface are defined, and accurate geometrical models are established. Secondly, the contact condition between the grinding wheel and the flute surface is deduced to calculate the grinding wheel profile by the envelop theory. Thirdly, an optimization method, including profile optimization and grinding wheel wear optimization, is proposed for the calculation of the grinding wheel profile. Finally, the method is verified by simulation machining and the results show that the method can improve the grinding precision and expand the application range of forming grinding technology in helical flute grinding.

“…By using the profle design method of forming tools based on the meshing principle and spline interpolation method, Tang et al [8] combined the contact line shape generated by the coordinated movement of the machine tool, screw, and tool with the spatial position parameters and proposed the form position geometry method (FPGM), which avoids the task of solving the frst derivative of each discrete point in the traditional contact line method. Shen et al [9] introduced the parametric design method of grinding wheel with an arbitrary groove on the spiral rake face of the tool. Li [10] introduced a grinding wheel contour calculation algorithm based on the envelope and analytic geometry theory.…”

In the development of modern tools, the flute (or profiling flute) after design optimization is often obtained by grooving with a forming grinding wheel. At present, the main method of reverse forming wheel profile is the analytical method, which needs to solve the contact line equation according to the contact conditions. It is difficult to solve the equation. The solution value is unstable, which leads to the design error of the grinding wheel profile. In order to solve this problem, this paper proposes a new algorithm, called the pixel matrix method for short. This method is based on the spiral motion envelope method and mathematical morphology. First, the cross-section of the flute is discretized into a point cloud, and then, the envelope motion is carried out in the grinding wheel coordinate system. Second, the point cloud of the grinding wheel radial section is collected and converted into a binary image of pixel points. Finally, the profile of the binary image is extracted by erosion and dilation. The optimized profile of the formed grinding wheel reaches the accuracy requirements of the design and processing in the actual machining verification. This method can accurately reverse the profile of the forming grinding wheel. The calculation process is intuitive, avoiding the solution of the contact line equation, and the solution value is stable. It provides a new way to reverse the profile of the machining tool for cylindrical spiral products.
