Abstract
The present invention relates to Machining Technology for Cutting fields, more particularly to a kind of milling method of weak rigid complex curved surface parts.When being processed to weak rigid complex curved surface parts, due to the problems such as part rigidity is insufficient, and there is machining deformations, flutter in process.And since part shape face complicated difficult is to improve processing rigidity by Auxiliary support, lead to the problems such as weak hard parts difficulty of processing is big, machining accuracy is difficult to ensure.The present invention is by being cast into the casting matrix with certain regular shape for weak rigid complex curved surface parts using low-melting alloy, again using entire casting matrix as machining blanks, it is processed in processing by adding Auxiliary support, on the one hand its processing rigidity is improved by low-melting alloy of casting, while regular shape is also beneficial to the addition of Auxiliary support when part processing.Flutter, the deformation in process are avoided, machining accuracy can be significantly improved.
Description
Technical field
The present invention relates to Machining Technology for Cutting fields, more particularly to a kind of Milling Process of weak rigid complex curved surface parts
Method.
Background technique
When processing to weak rigid complex curved surface parts, since part rigidity is insufficient, there is processing in process
The problems such as deformation, flutter.And since part shape face complicated difficult is to improve processing rigidity by Auxiliary support, lead to weak rigidity zero
The problems such as part difficulty of processing is big, machining accuracy is difficult to ensure.
Summary of the invention
In view of the shortcomings of the prior art, providing a kind of flutter and deformation that can be reduced in process, raising adds the present invention
The milling method of the weak rigid complex curved surface parts of work precision.
In order to solve the above-mentioned technical problem, the present invention is by being cast weak rigid complex curved surface parts using low-melting alloy
At the casting matrix with certain regular shape, then using entire casting matrix as machining blanks, pass through addition auxiliary branch in processing
Support is processed, and on the one hand improves its processing rigidity by low-melting alloy of casting, while regular shape is also beneficial to part
The addition of Auxiliary support when processing.
A kind of milling method of weak rigid complex curved surface parts, comprising the following steps:
(1) with the weak rigid complex curved surface parts blank of the low-melting alloy casting of melting, being formed has pouring for regular shape
Casting;
(2) cast is made to meet clamping shape and clamping precision requirement by machining;
(3) by cast clamping on machining tool;
(4) Milling Process is carried out to cast, while removes low-melting alloy and extra part material, obtained required
Complex curved surface parts;
(5) chip is collected, low-melting alloy therein recycling is used for next use.
In step (1), weak rigid complex curved surface parts blank is put into mold and is cast.
In step (2), external cutting is carried out by lathe.
In step (3), rigidity when cast processing is improved using certain Auxiliary support.
In step (4), it integrally regard casting matrix as blank, Milling Process is carried out to it.
The utility model has the advantages that improving processing rigidity by low-melting alloy casting, while regular shape is also beneficial to part and adds
The addition of working hour Auxiliary support improves the processing rigidity in weak hard parts process, avoids quivering in process
Vibration, deformation, can significantly improve machining accuracy.
Detailed description of the invention
Fig. 1 is the flow process chart of the weak rigid complex curved surface parts of the present invention.
Specific embodiment
With reference to the accompanying drawing and by taking blade processing as an example, of the invention is described in further detail.
A kind of linear leaf milling method, comprising the following steps:
Step 1: blade being positioned with tenon, clamping is on fixture;
Step 2: blade blade being partially placed into the mold processed, the low-melting alloy of fusing is poured into, guarantees eutectic
The point entire blade blade of alloy-coated;
Step 3: after low-melting alloy is cooling, by cast clamping, size, guarantee outer circle have one on lathe
Determine dimensional accuracy;
Step 4: by the cast clamping after processing on four-axis milling machine, using the device of similar backrest as auxiliary
Support, adjusts the position of Auxiliary support, guaranteeing it not influences the clamping precision of cast;
Step 5: planning cutter path for casting matrix as machining blanks, select suitable cutter and cutting parameter in four axis
Milling Process is carried out to cast on lathe;
Step 6: recycling chip separates low-melting alloy, and the low-melting alloy of recycling remains next use.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
