What is Hole Design?
Hole Design is essential knowledge for designing CNC machined parts. Standard drill sizes.
Key Principles
- Understand manufacturing constraints
- Design for cost-effectiveness
- Consider material properties
- Plan for quality inspection
Best Practices
Depth-to-diameter ratio.
- Communicate early with your machining partner
- Use standard features and sizes
- Specify tolerances only where critical
- Consider secondary operations
Common Mistakes to Avoid
- Overly tight tolerances
- Unnecessary complexity
- Ignoring tool access
- Poor datum selection
Why Follow These Guidelines?
Following Hole Design guidelines helps you:
- ✅ Reduce manufacturing costs
- ✅ Improve part quality
- ✅ Shorten lead times
- ✅ Avoid redesign iterations
