Problems solved by technology

[0004] The present invention provides a kind of method based on the non-orthogonal helical surface to generate the arc cutter body blade curve of the vertical milling cutter in order to solve the above-mentioned shortcomings, and solve the problem of the bottom of the circular arc nose end mill and the ball nose end mill in the prior art. The tooth blade curve does not have the tooth eccentricity and inclination angle, so that when the end mill bottom tooth blade curve participates in cutting, the strength of the end mill blade is poor. When the end mill bottom tooth does not participate in cutting, the bottom tooth blade is increased The problem of the tangential contact between the straight line blade curve and the cavity surface in the curve

[0137] When the edge curve of the bottom tooth of the end mill participates in cutting, the edge curve of the arc cutter body (including the curve of the bottom tooth edge, that is, including the straight edge curve and the S-shaped edge curve of the arc cutter body) can strengthen the edge strength by a certain distance from the center. When the edge curve of the bottom tooth of the end mill does not participate in the cutting, such as when milling the fillet of the cavity, only the S-shaped edge of the arc cutter body is required to participate in the cutting, and the straight edge curve is not required to participate in the cutting. If the straight edge curve has a certain internal The ...

Abstract

The invention discloses a method for generating arc cutter body blade curves of vertical milling cutters based on a non-orthogonal spiral surface, belongs to the technical field of vertical milling cutters and solves the design problems that an arc-end vertical milling cutter is provided with an off-center bottom tooth blade with an internally inclined property, and a ball-end vertical milling cutter is provided with an off-center bottom tooth blade in the prior art. The non-orthogonal spiral surface is built, an arc curved surface intersected with the non-orthogonal spiral surface is built, an internal inclination angle and a tooth inclination center distance are given, an arc cutter body S-shaped blade curve is built, and a straight blade curve of the vertical milling cutter is built on the arc cutter body S-shaped blade curve to obtain a design model of the straight blade curve and the arc cutter body S-shaped blade curve generally applied to the arc-end tooth vertical milling cutter and the ball-end vertical milling cutter. The method is used for generating the design model of the arc cutter body S-shaped blade curve generally applied to the arc-end tooth vertical milling cutter and the ball-end vertical milling cutter.

Description

technical field [0001] A method for generating an arc cutter body edge curve of an end mill based on a non-orthogonal helical surface, which is used to generate an S-shaped edge curve design for an arc head end-tooth end mill and a ball end mill. The model belongs to the technical field of end mills. Background technique [0002] When the bottom tooth edge curve of the end mill participates in cutting, the edge strength of the bottom tooth edge curve is poor. If the bottom tooth edge is deviated from the center by a certain distance, the edge strength can be enhanced; and when the end mill bottom tooth edge curve does not participate For example, when milling the fillet of the cavity, only the S-shaped blade of the arc cutter body is required to participate in the cutting, and the straight-line blade curve is not required to participate in the cutting. At this time, if the straight-line blade curve does not have a certain inclination angle, it will increase the The tangent ...
