Problems solved by technology

[0003] The common cutting method of aramid fiber composite materials is to use traditional cutting tools, which often have the following problems during processing: the cutting edge is not sharp, the surface roughness of the machined surface is poor, it is easy to produce threading, and the cutting efficiency is low; the cutting resistance is large and the cutting More heat, faster tool wear, and even denaturation of the resin base

Embodiment 1

[0018] A cutting processing method of an aramid fiber composite material, using a cutter 1 to first cut off the aramid fiber, and then cutting off the aramid fiber composite material 2 to be removed.

[0019] like Figure 1 to Figure 4 As shown, the cutter 1 is composed of two identical circular solid carbide cutting blades 6, 7 and a high-speed steel disc milling cutter 5, wherein the two identical circular solid carbide cutting blades 6 , 7 are symmetrically installed on both sides of the high-speed steel disc milling cutter 5. The circular solid carbide cutting blades 6 and 7 have a diameter of 80 mm, a thickness of 3 mm, and a wedge angle of 8° to 10°. The diameter of described high-speed steel disc milling cutter 5 is made into 79mm, the installation thickness is made into 2mm, and the rake angle of cutting edge is 0°~3°. 5 has a diameter difference of 1 mm.

[0020] The cutting parameters of the tool 1: the rotation speed is 800rpm, and the feed rate is 80mm / min.

Embodiment 2

[0022] A cutting processing method for an aramid fiber composite material, using a cutter 3 to first cut off the aramid fiber, and then cutting off the aramid fiber composite material 2 to be removed.

[0023] like Figure 5 to Figure 8 As shown, the cutter 3 includes a blade 8, a shank 9 and a connecting hole 10 for connecting with a tool chuck. The blade 8 is in the shape of a strip in the feeding direction of the cutter, and several serrated cuts The units are arranged in two rows along a straight line on the blade portion 8, the cutting units in each row have the same structure, and the cutting units in the two rows are arranged symmetrically and staggered in the direction of tool feed. The centripetal angle of the blade portion 8 is 5°. The normal rake angle of the cutting edge on the one row of cutting units is 60°, and the normal rake angle of the cutting edge on the other row of cutting units is 45°.

[0024] The cutting parameters of the tool 3: the cutting speed is...

Abstract

The invention provides a cutting processing method of an aramid fiber composite material, which firstly cuts the aramid fiber by using a cutter, and then cuts off the aramid fiber composite material to be removed. Said tool consists of two identical round solid carbide cutting blades and a high-speed steel disc milling cutter, alternatively, said tool comprises a blade, a shank and an attachment hole for attachment to a tool holder, The blade is in the shape of a strip in the feeding direction of the tool, and several cutting units are arranged in two rows along a straight line on the blade. Adopting the present invention, its cutting quality and cutting efficiency are obviously superior to the existing cutting processing method of aramid fiber composite material, the cutting processing efficiency is at least 2 times higher than the original one, and the processing quality is at least 1 grade higher than the original one.

Description

technical field [0001] The invention relates to a cutting processing method of an aramid fiber composite material. Background technique [0002] Aramid fiber composite materials have many advantages such as high strength-to-weight ratio and good impact resistance, so they have been more and more widely used in aerospace manufacturing. However, aramid fiber composite material is a kind of material that is difficult to cut and process. It is usually made of aramid fiber, resin and other materials, and has the characteristics of good toughness and not easy to cut. [0003] The common cutting method of aramid fiber composite materials is to use traditional cutting tools, which often have the following problems during processing: the cutting edge is not sharp, the surface roughness of the machined surface is poor, it is easy to produce threading, and the cutting efficiency is low; the cutting resistance is large and the cutting The heat is greater, the tool wears faster, and eve...
