Problems solved by technology

And because the honeycomb material is a material with a light weight and a special structure that is not easy to hold, it is easy to be pulled up during the processing process, causing the parts to be scrapped due to milling errors
[0004] Milling of honeycomb parts also produces a large amount of cutting dust that is not conducive to environmental protection and the health of operators

Embodiment Construction

[0011] According to the shape of the part, choose a reasonable size sheet milling cutter and small cylindrical milling cutter. The diameter of the small cylindrical milling cutter should be slightly larger than the diameter of the cutter bar of the chip milling cutter, so as to ensure that the cutter bar will not interfere with the material during the processing of the chip milling cutter. First, according to the slope of the curved surface shape to be milled for the honeycomb part material workpiece to be structured, a small cylindrical milling cutter is used to mill out several vertically arranged small grooves with different heights above the curve, as shown in Figure 1. The groove of a typical honeycomb material. When using a small cylindrical milling cutter to open several small grooves, the distance between the small grooves should be smaller than the radius of the piece milling cutter, so as to ensure that the piece milling cutter can cut off the remaining material smoot...

Abstract

The invention discloses a milling method for a honeycomb component. The milling method is characterized in that a plurality of vertically-arranged small grooves are milled at the upper part of the curve surface through a small cylinder milling cutter according to the slope of the milling curve surface required of honeycomb component materials, then the cutting process is performed along the formerly-milled small grooves through the milling cutter, and the profile shape required is formed through milling. The invention solves the problems that the drop height of the milling profile of the honeycomb component is big, the chipping allowance thereof is big, the cutting force is great during milling, the honeycomb materials is not easy to fix, and the process is pulled up easily so that the honeycomb component is discarded during milling.

Description

technical field [0001] The invention relates to a milling method of honeycomb material parts, which can be applied to the milling process of honeycomb and other light material parts. Background technique [0002] In the prior art, in order to enhance the unidirectional strength of the hollow parts of some parts and reduce the weight of the parts, it is usually filled with metal or non-metallic honeycomb materials with light weight and high unidirectional strength. In the prior art, the milling of honeycomb material parts generally uses an end mill to perform layered milling on the honeycomb parts, and the parts are formed by milling all the redundant materials into chips. [0003] During the milling process, the geometrical surface of the honeycomb part has a large drop in height, such as a wavy curved surface, and the cutting allowance is large, which will generate a large cutting force during milling. And because the honeycomb material is a material with a light weight an...
