Groove machining and hole machining are difficult to machine during aerospace material processing. For example, engine disc parts, shaft parts, and machine parts are very demanding on machining tools. Therefore, high-performance carbide standard tools and carbide non-standard tools are used in the processing of such parts. . The choice of tools in actual machining should consider the following factors: workpiece material, workpiece shape, machining requirements, machine tools, system rigidity, and surface quality technical requirements.
Taking turbine casing parts as an example, it is widely used in the analysis of workpiece materials, such as deformed superalloys and cast superalloys. These difficult-to-machine materials have small thermal conductivity, high strength, high cutting temperature, easy work hardening, and cutting tools. Fast wear, short tool life and high tool consumption, so the tool geometry must be chosen reasonably. From the perspective of the structure of the workpiece, the wall is thin, the rigidity is poor, and it is difficult to process. When machining the convex part of the part, the tool system easily interferes with the parts and fixtures. Therefore, the tool path must be optimized, such as insert milling instead of side milling, fast stroke fast path, optimized lifting position, and spiral interpolation. Milling. From the analysis of the machining process, the machine needs to be roughed, semi-finished and finished. In order to save the tool cost, high-performance ceramic milling cutter can be used for rough machining when manufacturing such parts. During semi-finishing and finishing The use of standard carbide tools and non-standard high-performance special tools can significantly improve production efficiency. In terms of processing economy, the tool configuration plan needs to be continuously improved, and the latest products developed by the tool manufacturer should be used as much as possible.
Therefore, tool suppliers should constantly understand the needs of users, not only to supply high-quality tools to users, but also to provide users with feasible tool solutions, regular training, and advanced cutting technology, high-end cutting concepts to the user's technical staff. . Improve aerospace companies' cutting technology through effective integrated tooling technology support. This will create a good atmosphere for the aerospace manufacturing users and tool suppliers to achieve a win-win situation.
