The integral impeller is a typical five-axis machining part, and how to compile a correct and efficient machining program is its key technology. The editor below will briefly introduce the key points to note when milling five-axis impellers.

The key points to note when milling a five-axis impeller are as follows:

1. Compared with side blade processing and tool bottom edge processing, blade processing can obtain a smoother processing surface. For finishing machining of complex cavity workpieces in the aerospace industry.

2. Five-axis high-efficiency roughing, five-axis linkage roughing, and a fully automatic cutter axis control method are used to avoid drastic changes in the cutter axis during roughing.

3. The three-axis tool path is used to process the five-axis tool path. For some workpieces, the three-axis tool path can be programmed first: it can be converted into a five-axis tool path in the multi-axis module. The five-axis tool path automatically generates the tool axis, optimizes the original tool path data, and includes complete five-axis collision detection.

4. In five-axis programming, it is often necessary to consider the interference between the tool axis and the workpiece in the tool path.

5. Through five-axis programming, the forward and side inclination angles of the cutter axis can be automatically adjusted, and the cutter axis can be automatically tilted according to the specified tolerance in areas where collision may occur to avoid the collision area; the cutter axis can be automatically adjusted after cutting through the collision area. Return to the original set angle to avoid collision between the tool and the workpiece.

6. Cutting point control can ensure that the cutting point of the tool is in contact with the surface of the part without changing any parameters to avoid cutting traps. The feed speed between designated areas, designated connections or section connections can also be adjusted, ultimately making the tool path cut into the workpiece smoother.

7. The tool position distribution is optimized, and the number of tool nodes can be controlled on each tool path. Combining the powerful big data processing capabilities of advanced machine tools can increase the number of cutting nodes on the tool path and control the way the cutting points are distributed.

Through optimization, the quality of finished surfaces can be further improved; stable tool load reduces tool wear rate; stable processing ensures high-precision operation of machine tools.
