Abstract

The invention designs a machining method for milling two curved surfaces of a tapered honeycomb variable-thickness structural part. The machining method is characterized by comprising the following steps of: 1) clamping an equal-thickness honeycomb solidified body so as to position a reference surface and a reference hole of a die; 2) arranging a special honeycomb scale milling cutter for machining a honeycomb on a five-shaft linkage milling machine; 3) setting a cutter rotating center distance of the honeycomb scale milling cutter on the five-shaft linkage milling machine; 4) making the reference surface of the part die a machining reference surface; 5) setting a cutting parameter of the honeycomb scale milling cutter according to a curvature of the machined double-curved-surface tapered honeycomb variable-thickness structural part; and 6) setting a milling path and a milling screw pitch of the honeycomb scale milling cutter according to the variable curvature of the tapered honeycomb variable-thickness structural part, so that the honeycomb scale milling cutter performs milling machining along a spiral trace. By the method, high curvature transition can be realized; therefore, double-curved-surface continuous machining on the surface of the machined part can be realized, damage to the part is avoided and the requirement of the curvature of the machined surface can be met.

Description

The hyperboloid milling method of taper honeycomb Varying-thickness structural member
Technical field
The present invention relates to a kind of hyperboloid milling method of taper honeycomb Varying-thickness structural member, belong to the field of machining of cellular material structural member.
Background technology
Originally the processing of general honeycomb all is equal thickness, the machining of rule shape part, method generally is according to being become two-dimentional strip boards by the expansion profile blanking of Seiko part with the equal thickness honeycomb board, then splice and combine into the profile state of required processing parts, when in machining, realizing Varying-thickness materials processing like this, under the automated programming control of CNC milling machine, a kind of is vertical milling, tool marks appear walking in piece surface, another kind is the lateral circumferential ring cutting, rib appears chewing or going out in piece surface, is difficult to realize curved surface continuously and the processing on Varying-thickness structural member fairing surface.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hyperboloid milling method of taper honeycomb Varying-thickness structural member, the method can realize good curvature transition, the treatment of surfaces of components realization hyperboloid is processed continuously, avoided injuring part, finally realize the curvature requirement of finished surface.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of hyperboloid milling method of taper honeycomb Varying-thickness structural member is characterized in that may further comprise the steps:
1) the equal thickness honeycomb is solidified into the body clamping to five axle interlock milling machine work tops, with datum level and the datum hole location of supporting mould;
2) at five axle interlock milling machines the special-purpose honeycomb goldfish scale milling cutter of processing honeycomb is installed;
3) the actual cutter length according to the honeycomb goldfish scale milling cutter arranges the honeycomb goldfish scale milling cutter in the cutter pivot distance of five axle interlock milling machines;
4) take the datum level of component die as processing datum;
5) cutting parameter of honeycomb goldfish scale milling cutter is set for the curvature of processed hyperboloid taper honeycomb Varying-thickness structural member;
6) according to the variation curvature of taper honeycomb Varying-thickness part, milling path and the milling pitch of honeycomb goldfish scale milling cutter is set, make the honeycomb goldfish scale milling cutter carry out milling processing with spiral trajectory.
Described honeycomb goldfish scale milling cutter carries out milling processing with spiral trajectory, its movement locus is that cutter direction of advance and its downward vertical direction add 15 simultaneously feedings of degree both direction, form helical form, pitch forms spiral taper curved surface and carries out milling less than or equal to 3mm.
The hyperboloid milling method of this taper honeycomb Varying-thickness structural member has adopted the spiral milling, changed original in cutting and crosscut, make the processing of hyperboloid taper honeycomb Varying-thickness structural member after, precision improves greatly, has also improved operating efficiency simultaneously.
Description of drawings
Fig. 1 is the hyperboloid milling machining locus schematic diagram of taper honeycomb Varying-thickness structural member.
Wherein 1, spiral milling machining locus; 2, the initial initial point of tool sharpening; U, tool sharpening direction of advance; The direction that V is vertical with the tool sharpening direction of advance; The pitch of t, spiral milling machining locus.
The specific embodiment
A kind of hyperboloid milling method of taper honeycomb Varying-thickness structural member is characterized in that may further comprise the steps:
1) the equal thickness honeycomb is solidified into the body clamping to five axle interlock milling machine work tops, with datum level and the datum hole location of supporting mould;
2) at five axle interlock milling machines the special-purpose honeycomb goldfish scale milling cutter of processing honeycomb is installed; This milling cutter is commercial namely available;
3) the actual cutter length according to the honeycomb goldfish scale milling cutter arranges the honeycomb goldfish scale milling cutter in the cutter pivot distance of five axle interlock milling machines;
4) take the datum level of component die as processing datum;
5) cutting parameter of honeycomb goldfish scale milling cutter is set for the curvature of processed hyperboloid taper honeycomb Varying-thickness structural member;
6) according to the variation curvature of taper honeycomb Varying-thickness part, milling path and the milling pitch of honeycomb goldfish scale milling cutter is set, make the honeycomb goldfish scale milling cutter carry out milling processing with spiral trajectory.
When the bi-curved curvature of taper honeycomb Varying-thickness structural member changed between 152 ~ 633, the cutting parameter that the honeycomb goldfish scale milling cutter is set was 18000 revolutions per seconds of rotating speeds, cutting feed rate 1200 mm/second.Precise and penetrating direction is laterally to be U, vertically be the V+15 degree, other simultaneously feed of a direction, and pitch is less than or equal to 3mm, and one-tenth spiral taper track cuts the curved surface of taper honeycomb Varying-thickness structural member.Wherein vertically for the V+15 degree is material to be taken away when the high-speed cutting cellular material for the fish scale tooth that guarantees to reduce the honeycomb goldfish scale milling cutter, avoid materials processing wildness thorn, and guarantee the quality on milling surface.
