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
Technical field
The present invention relates to a kind of hyperboloid milling method of taper honeycomb thickening degree 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, splice and combine into the profile state of required processing parts then, when in machining, realizing the materials processing of thickening degree 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 that curved surface continuously and the processing on thickening degree 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 thickening degree structural member, this 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 thickening degree structural member is characterized in that may further comprise the steps:
1) the equal thickness honeycomb is solidified on body clamping to the five interlock milling machine table face, with the datum level and the datum hole location of supporting mould;
2) the special-purpose honeycomb goldfish scale milling cutter of processing honeycomb is installed on five interlock milling machines;
3) the actual cutter length according to the honeycomb goldfish scale milling cutter is provided with the cutter pivot distance of honeycomb goldfish scale milling cutter at five interlock milling machines;
4) datum level with component die is a processing datum;
5) cutting parameter of honeycomb goldfish scale milling cutter is set at the curvature of processed hyperboloid taper honeycomb thickening degree structural member;
6) according to the variation curvature of taper honeycomb thickening degree part, the 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 degree both direction feedings simultaneously, form helical form, pitch forms spiral taper curved surface and carries out milling smaller or equal to 3mm.
The hyperboloid milling method of this taper honeycomb thickening degree structural member has adopted the spiral milling, changed original in cutting and crosscut, make the processing of hyperboloid taper honeycomb thickening degree structural member after, precision improves greatly, has also improved operating efficiency simultaneously.
