Problems solved by technology

[0003] The allowance in the processing process of the prior art is too large and uneven, the tool extension length is too long, exceeding 5 times the diameter, the processing parameters are unreasonable, the F, S, depth of cut do not match, and the tool wears seriously during processing Failure to replace it in time, insufficient air blowing during processing, failure to discharge iron slag in time, and unreasonable programming of the cutting method will all lead to the occurrence of knife bounce.

Embodiment 1

[0034] A method for treating and preventing knife snapping, comprising the following steps: the position where the knife snapping is likely to occur is the inner side of the boss shape, and the auxiliary surface is protected after roughening, so that the narrow area does not generate a tool track.

Embodiment 2

[0036] A method for treating and preventing the snapping of knives, comprising the following steps: the position where the snapping of knives is likely to occur is between the boss and the boss, the R between the boss and the boss is 0.5mm, and the middle light is cleared before the angle Use the R1 ball knife to make the thickness to a margin of 0.3mm, and then use the medium light to clear the corner to a margin of 0.1mm.

Embodiment 3

[0038] A treatment and preventive method for snapping knives, including the following steps: the position where the snapping knives are prone to occur is the side of the V-shaped groove, the auxiliary surface is protected first, and then EDM processing is performed. Coarse to a margin of 0.3mm, and then clear the corners to a margin of 0.1mm to keep the trimming range of the tool path consistent. After generating the tool path, delete the tool path on the side of the V-groove.

Abstract

The invention provides a method for treating and preventing overcutting. The method comprises the following steps: the position where overcutting is prone to occurring on a mold is determined firstly,and the position where overcutting is prone to occurring is machined. The method for treating and preventing overcutting is suitable for numerical control machine tool machining of the injection mold, and overcutting of faces in similar shapes is avoided.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a method for treating and preventing a bullet knife. Background technique [0002] With the increasing requirements for the processing accuracy of parts in various fields, the requirements for molds for processing parts are also increasing, and the dimensional accuracy of molds directly affects product quality. The processing efficiency, precision and qualified rate of the mold will affect the cost of production. Because it is used in different industries, products and equipment, the requirements for the processing accuracy of the mold are also varied. [0003] The allowance in the processing process of the prior art is too large and uneven, the tool extension is too long, exceeding 5 times the diameter, the processing parameters are unreasonable, the F, S, depth of cut do not match, and the tool is severely worn during processing Failure to replace it in time, i...
