Problems solved by technology

If the forming diamond roller is used to trim the surface of the grinding wheel, the manufacturing precision of the diamond roller is required to be high, and the surface is complex. After the combined effects of the manufacturing error, installation error and machine tool error of the diamond roller, the error of the trimmed grinding wheel is large, which is harmful to the development. The accuracy of the machined tooth surface is greatly affected, and the grinding contact area is large when the forming method is trimmed, the heat is high, it is not universal, and it is difficult to use and maintain in actual production applications

Embodiment Construction

[0039] The schematic diagram of the shape of the diamond roller is shown in figure 1 , the part used for trimming and cutting is the fillet of R1. The principle of trimming involute profile grinding wheel by offset curve method is as follows: figure 2 As shown, the cross-sectional shape of the special grinding wheel for face gear grinding is convex involute shape. Since the face gear grinding process uses one side of the grinding wheel for processing, only the worn side of the grinding wheel is needed for each dressing. Use the software to parametrically model the involute to be trimmed, and make a 1mm outer offset curve on the side to be trimmed, and take a series of points on the offset curve according to the accuracy requirements to pass through these broken lines As the movement trajectory during trimming, the coordinate data of these points is obtained through the software, and the relative coordinates between each two points are calculated, so as to obtain the G code o...

Description

technical field [0001] The invention relates to a numerical control dressing control device and control method for a special grinding wheel for face gear grinding, which is suitable for dressing processing of a special grinding wheel for face gear grinding with any modulus and pressure angle. Background technique [0002] Grinding wheel dressing is the operation process of using dressing tools to shape the grinding wheel or remove the blunt surface layer to restore the grinding performance and correct geometry of the working surface of the grinding wheel. In the process of grinding face gears with a special grinding machine for face gears, trimming the size, shape, and geometric angle of the grinding wheel is a necessary link to ensure the correctness of the processed face gear profile and surface quality. [0003] Grinding machines for face gears use involute-profile grinding wheels, and the tooth surfaces of opposite face gears are finished by generating motion. If the fo...
