The method of obtaining the shape accuracy of the stamping parts in the stamping processing order

As everyone knows, the machining accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the processed part with the ideal geometric parameters specified in the drawing. This article is about the part about the shape accuracy, how to obtain the shape accuracy of the stamping parts in the stamping processing order, let's take a look with the author below. 1. Trajectory method This type of processing method uses the trajectory of the tool tip movement to form the shape of the processed surface. General turning, milling, planing and grinding all belong to the tool tip trajectory method. The shape accuracy obtained by this method mainly depends on the accuracy of the forming movement. 2. Forming method The geometry of the forming tool is used to replace certain forming movements of the machine tool to obtain the machined surface shape. Such as forming turning, milling, grinding, etc. The shape accuracy obtained by the forming method mainly depends on the shape of the blade. 3. Generating method Use the envelope surface formed by the tool and the workpiece to generate the shape of the machined surface, such as gear hobbing, gear shaping, gear grinding, knurling splines, etc., all belong to the generative method. The shape accuracy obtained by this method mainly depends on the shape accuracy and generative motion accuracy of the blade.
