Problems solved by technology
[0003] The purpose of the present invention is to solve the problem of severe wear of the grinding wheel when using the array profiling grinding wheel in the grinding process of the cylindrical array structure of the high-order curve section; and the grinding of the single arc grinding wheel requires repeated grinding of the array structure unit. Due to the long processing cycle and high cost of the workpiece, a method for precision grinding of high-order curve cross-section cylindrical array structures using arc array grinding wheels with variable tangency points is proposed

The invention discloses a method for grinding a high-order curve cross-section cylinder array structure by using an arc array grinding wheel. The variable tangent point reciprocating grinding is carried out on the array cylinder, and the movement trajectory of the grinding wheel in the plane of the high-order curve section of the cylinder is an equidistant parallel line with a distance r from the high-order curve. After the grinding wheel changes the tangent point once in the plane of the high-order curve section, it makes a reciprocating motion in the direction perpendicular to the plane of the high-order curve section to complete the grinding of a generatrix of the cylindrical surface. Since the grinding wheel has an array structure, as long as the grinding of one cylinder structure unit in the array structure is completed, the grinding process of all cylinder arrays with high-order curve cross-sections can be realized. And after the cross-sectional unit structure of the grinding wheel is trimmed into a circular arc, the interpolation movement of the machine tool is used to ensure that the tangent point between the grinding wheel and the workpiece forms a high-order curve, and the array structure is ground with variable tangent points, and the grinding accuracy is high.
Description
technical field [0001] The invention relates to a grinding processing method, which uses an arc array grinding wheel to carry out variable tangent point precision grinding on a high-order curve section cylinder array, and only needs to perform one grinding cycle on the array unit to complete the forming grinding of the array structure . Background technique [0002] In industries such as automobiles, electronics, and optics, it is necessary to process a large number of high-order curved cross-section cylindrical array structures, and the requirements for shape accuracy and surface quality are getting higher and higher. At present, the methods for precise grinding of the array structure can be mainly divided into two categories. The first type is to trim the section of the grinding wheel into a shape that matches the array structure, and directly perform profiling grinding on the array structure. The advantage of this method is that the processing efficiency is high, but the...
