Abstract
The invention relates to the technical field of cutting machining, in particular to a milling method for a weak-rigidity complex curved surface part. When a part with weak rigidity and a complex curved surface is processed, due to the insufficient rigidity of the part, the problems of processing deformation, flutter and the like exist in the processing process. And the processing rigidity is difficult to improve through the auxiliary stay because the part shape is complicated, lead to weak rigidity part processing degree of difficulty big, processing precision difficult to guarantee etc. difficult problem. According to the invention, the low-melting-point alloy is utilized to cast the weak-rigidity complex curved surface part into the casting body with a certain regular shape, then the whole casting body is used as a processing blank, and the processing is carried out by adding the auxiliary support during processing, so that on one hand, the processing rigidity is improved by casting the low-melting-point alloy, and meanwhile, the regular shape is also beneficial to adding the auxiliary support during processing of the part. Avoiding the flutter and deformation in the processing process and obviously improving the processing precision.

Aiming at the defects of the prior art, the invention provides the milling method of the weak-rigidity complex curved surface part, which can reduce the vibration and deformation in the processing process and improve the processing precision.
In order to solve the technical problems, the low-melting-point alloy is used for casting the complex curved surface part with weak rigidity into the casting body with a certain regular shape, then the whole casting body is used as a processing blank, and the processing is carried out by adding the auxiliary support during processing, so that on one hand, the processing rigidity is improved by casting the low-melting-point alloy, and meanwhile, the regular shape is also beneficial to adding the auxiliary support during processing of the part.
A milling method for a weak-rigidity complex curved surface part comprises the following steps:
(1) casting a weak-rigidity complex curved surface part blank by using molten low-melting-point alloy to form a casting piece with a regular shape;
(2) the casting part meets the requirements of clamping shape and clamping precision through cutting;
(3) clamping the casting on a processing machine;
(4) milling the casting piece, and removing low-melting-point alloy and redundant part materials to obtain a required complex curved surface part;
(5) the swarf is collected and the low melting point alloy is recovered for the next use.
In the step (1), the blank of the weak-rigidity complex curved surface part is placed into a mould for casting.
In the step (2), the outer circumference is cut by a lathe.
In the step (3), certain auxiliary support is adopted to improve the rigidity of the casting piece during processing.
In step (4), the whole of the cast body is milled as a blank.
Has the advantages that: the processing rigidity is improved through the low melting point alloy casting, the regular shape is also favorable for the addition of auxiliary support during part processing, the processing rigidity in the processing process of weak-rigidity parts is improved, the flutter and deformation in the processing process are avoided, and the processing precision can be obviously improved.
