Abstract

The invention provides a numerical control finish turning processing method of an annular Omega-shaped groove of a titanium alloy thin wall disc ring piece. The numerical control finish turning processing method of the annular Omega-shaped groove of the titanium alloy thin wall disc ring piece includes: confirming an allowance in each finish turning processing stage of the annular Omega-shaped groove of the titanium alloy thin wall disc ring piece; confirming a processing scheme of the finish turning stages of the annular Omega-shaped groove of the titanium alloy large diameter thin wall disc ring piece; compiling a numerical control turning program of the finish turning stages of the annular Omega-shaped groove of the titanium alloy large diameter thin wall disc ring piece; controlling a processing route of each numerical control finish turning processing stage of the annular Omega-shaped groove of the titanium alloy thin wall disc ring piece. The numerical control finish turning processing method of the annular Omega-shaped groove of the titanium alloy thin wall disc ring piece breaks a technical bottleneck in processing of a titanium alloy piece of special structure, improves processing efficiency on the premise of meeting processing technology requirements of the annular Omega-shaped groove of the titanium alloy large diameter thin wall disc ring piece in numerical control turning of a titanium alloy material supercharging first stage disc, achieves high efficiency processing of the annular Omega-shaped groove of the titanium alloy large diameter thin wall disc ring piece, solves the problems that the annular Omega-shaped groove of the titanium alloy large diameter thin wall disc ring piece is low in processing efficiency and long in machine occupying time, and alleviates production bottlenecks in machining of a vertical lathe.

Description

technical field [0001] The invention relates to the technical field of mechanical numerical control machining, in particular to a numerical control finishing machining method for an annular Ω groove of a titanium alloy thin-walled disk ring. Background technique [0002] In the field of mechanical processing technology, especially in titanium alloy processing and manufacturing, the processing of titanium alloy disc parts and the annular Ω groove of large-diameter and thin-walled parts is a major technical difficulty. Conditions, low work efficiency and machining accuracy are difficult to meet the requirements of parts and production. Such parts generally appear in advanced models. The efficiency of their development and processing is extremely low and the repair rate is high. Controlling deformation is also a major difficulty. Due to the limitation of on-site production conditions, general disk parts are processed on the CNC horizontal lathe, and there are certain deformati...

AI Technical Summary

Problems solved by technology

The structure of the part is complex, and the CNC machining route and method will directly affect the processing efficiency and quality of the part. Therefore, whether the size and technical conditions can meet the requirements of the design drawings, the CNC machining tool routing, that is, the processing concept plays a vital role.

[0003] At the present stage, the production site generally adopts the contour mode trial cutting method for processing. This kind of NC program is more flexible in processing, and the contour points and the position of the advance and retreat tools can be adjusted and modified at will, but it requires high-tech operators with processing experience to complete the development and processing. , otherwise some dimensions and technical conditions are difficult to guarantee

During the processing, the operator groped for tool compensation based on his own processing experience. The material of this part is titanium alloy, which is a difficult-to-machine material, and the characteristics of the part are not easy to form. If the processing is not in place, additional processing is required. The cutting force is relatively large, which may not meet the size and technical requirements of the part
