9、 Structural Design of Machined Parts（Problems needing attention in mold design of 500 cases）

1. Pay attention to reducing the blank size
The machined surface and the non machined surface should not be flush
3. Reduce the length of the machined surface
4. Surfaces with different machining accuracy should be separated
5. Changing parts with complex shapes into assemblies for ease of processing
6. Avoid unnecessary accuracy requirements
7. The tool is easy to enter or exit the machining surface
8. Avoid processing enclosed spaces
9. Avoid the tool not being able to approach the workpiece
10. Do not use structural shapes of parts that are not suitable for the shape of the tool
11. The impact of casting errors should be considered
12. Avoid combined processing of multiple parts
13. Complex machined surfaces should be designed on the outer surface rather than the inner surface
14. Avoid chamfering complex shaped parts
15. It is necessary to avoid the seam fitting of non circular parts
16. Avoid unnecessary supplementary processing
17. Avoid parts that cannot be clamped
18. Avoid part structures without measurement base surfaces
19. Avoid shock and vibration during processing
20. Avoid drilling on inclined surfaces
21. The bottom of the through-hole should not be partially undrilled
22. Reduce the number of tools used to process the same part
23. Avoid multiple fixation during processing
24. Pay attention to the possibility of machining multiple parts at one time
