A Controlled Deformation Machining Technology of Thin-walled Disk Parts

Abstract

Provided is a machining process controlling deformation of a thin-wall disk part. The disk part is machined through a lathe in a dispersed feed mode so that machining of the same plane is finished during a plurality of dispersed cutting processes. Feed (1) includes that the direction of the feed is from outside to inside so that cutting force of the part points at a disk center and rigidity of the part is improved; feed (2) includes that the machining is carried out from the disk center to the outside so that the cutting force points to the inside of a disk body and compression stress of the disk body is enhanced; and feed (3) includes that the machining is carried out from an arc high point to a low point. The direction of feed (4) is opposite to that of the feed (3) so that stress balance of the whole part is ensured and the rigidity of the disk body is enhanced. After the machining of the feed (1), the feed (2), the feed (3) and the feed (4), a large amount of allowance is eliminated, finish machining is carried out through feed (5), feed (6), feed (7) and feed (8), and the directions of the feed (5), the feed (6), the feed (7) and the feed (8) are the same as those of the feed (1), the feed (2), the feed (3) and the feed (4). Therefore, the stress of the whole disk body part is kept balanced during the final machining process. The machining process has the advantages of improving machining efficiency and quality, reducing the frequency of repeated locating, improving machining precision of the part, and enabling the deformation degree of the disk body part to be well controlled.

Description

technical field [0001] The invention relates to the field of numerical control machining, and in particular provides a process for controlling deformation of thin-walled disk parts. Background technique [0002] The traditional part processing method is mainly to calculate the node data value according to the outline size of the part, and carry out numerical control programming according to this value. Repeated processing by way of cutting tool will generate stress in the same direction on the surface of the part, which will increase the degree of stress and deformation during part processing. Contents of the invention [0003] The object of the present invention is to reduce the deformation of parts during processing, and especially provides a processing technology for controlling deformation of thin-walled disk parts. [0004] The invention provides a thin-walled disk part controlled deformation processing technology, which is characterized in that: the thin-walled disk...
