Problems solved by technology

[0002] In the past, the formed milling cutter was processed on the shovel bed, and the formed milling cutter (straight tooth or helical tooth) produced by the shovel often failed to meet the accuracy requirements after the milling test, that is, distortion occurred, and the exact cause of the distortion could not be found. , so such a high-precision form milling cutter has not been popularized and applied
The characteristics of high efficiency, low consumption and precision of form milling cutter have not been shown

Embodiment Construction

[0015] see figure 1 and figure 2 As shown, first, in order to avoid the distortion caused by different starting points, the upper plane of the shovel blade 2 and the rake face of the formed milling cutter 1 to be shoveled should be on the same horizontal plane, (such as figure 1 shown), only in this way can the shovel move from point C to point D of the forming milling cutter (points C and D respectively represent the highest point and the lowest point of a certain section on the cutting edge of the forming milling cutter, and also represent the corresponding The highest point and the lowest point of the segment) are guaranteed to be on the same shoveling point. That is to say, the shovel back curve at point D and the shovel back curve at point C are the shovel back curves in the same lift angle, thus avoiding the distortion caused by inconsistent starting points. Second, the top view shape of the shovel blade 2 head should be made (see figure 2 ) is consistent with the s...

Abstract

The processing method for precisely backing-off cutting form milling cutter includes: eliminating distortion resulted from different cutting initiation points, i. e. defining height of upper tool face of cutter, making form of tool nose of cutter must fit with contact heat form and eliminating transmission distortion, and defining arc of tool nose of cutter and included angle of tool nose of the cutter, and eliminating distortion which can be produced in course of cutting. The advantages of said invention are: eliminating various distortions and providing a method for precisely backing-off cutting form milling cutter.

Description

Technical field: [0001] The invention relates to a method for shoveling a forming milling cutter, in particular to a processing method for accurately shoveling a forming milling cutter on a shovel bed. Background technique: [0002] In the past, the formed milling cutter was processed on the shovel bed, and the formed milling cutter (straight tooth or helical tooth) produced by the shovel often failed to meet the accuracy requirements after the milling test, that is, distortion occurred, and the exact cause of the distortion could not be found. , so such a high-precision form milling cutter has not been popularized and applied. The characteristics of high efficiency, low consumption and precision of form milling cutter have not been shown. Invention content: [0003] The purpose of the present invention is to design a processing method for accurately shoveling forming milling cutters, which eliminates the distortion phenomenon in profiling shoveling of forming milling cut...
