Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other co...

Abstract

The invention discloses a blisk-like parts processing system and method based on the combination of electric arc discharge and milling. The rough machining of the blisk-like parts is completed by negative arc machining, and most of the materials to be removed are removed; The semi-finishing of the blisk parts is processed; finally, the finishing of the blisk parts is completed by milling. Step-by-step machining is done on the same machine tool. The invention significantly improves the machining efficiency of difficult-to-machine material blisks, significantly shortens the machining time, uses cheap graphite electrodes to replace expensive cutters in the rough and semi-finishing stages, reduces the machining cost, and the machining process is performed on a special machine tool at a high cost. The quality is completed, and the integration and integration of arc discharge machining and milling machining are realized, with fewer processing steps.

Description

technical field [0001] The invention relates to the processing technology of blisk parts, in particular to a processing system and method for blisk parts based on the combination of arc discharge and milling. Background technique [0002] Most of the existing blisk parts processing technology uses special cutting tools for difficult-to-machine materials for rough and finish machining. However, due to the poor characteristics of titanium alloys and nickel-based superalloys during processing, the tools are inevitably worn out and the use time is extremely limited. Such tools are often expensive, and frequent tool replacements lead to rising processing costs, which greatly increases Its application cost; at the same time, titanium alloys and nickel-based superalloys also have problems such as lengthy processing time, and the processing accuracy cannot be effectively guaranteed during continuous processing, which cannot be effectively solved by traditional cutting processing. ...
