Techniques, safety guidelines, and operational best practices for vacuum workholding
Operational Best Practices
Do:
- Test the hold before starting
- Use light to moderate feed rates
- Keep operations over the pod center when possible
- Use mechanical stops for anti-rotation
Don't:
- Apply aggressive side-loads
- Create large moment arms away from the pod
- Pry against the seal
Do:
- Triangulate pod placement
- Add pods at corners and mid-spans
- Use fences or rails for alignment
- Test stability before cutting
Don't:
- Underestimate the pod count needed
- Ignore edge support requirements
- Skip checking for flat contact
Application-Specific Guidance
Best practices:
- Clean surfaces before clamping
- Use consistent pressure across the workpiece
- Work over pod locations when possible
- Release vacuum smoothly to prevent movement
Advantages:
- Clamp-free access to entire surface
- Quick workpiece changes
- No clamp marks or interference
Best practices:
- Use appropriate feed rates and depths of cut
- Take lighter passes to reduce side-loads
- Add mechanical stops for anti-rotation
- Support large workpieces with multiple pods
Important:
- Test the hold with light force before starting
- Monitor for slip during operation
- Stop immediately if workpiece moves
Not recommended:
- Heavy machining without secondary restraint
- High side-load operations
- Aggressive plunge cuts
Best practices:
- Position pods to resist the cutting direction
- Use fences for consistent edge referencing
- Keep router or saw feed smooth and controlled
Advantages:
- Access to edges without clamp interference
- Quick repositioning for multiple edges
Preventing Racking & Rotation
Triangulate pod placement:
- Three or more pods in non-linear arrangement
- Creates stable platform resisting rotation
Add mechanical stops:
- Bench dogs as edge references
- Fences for indexing
- MFT stops and accessories
Reduce aggressive side-loads:
- Lighter passes during machining
- Controlled feed rates
- Appropriate tooling for the material

Safety Guidelines
Always:
- Clean work surface and gasket contact areas
- Apply vacuum and verify stability
- Test for movement with light force
- Wear appropriate PPE (eye and hearing protection)
Never:
- Begin cutting without testing the hold
- Ignore audible air leaks
- Proceed if workpiece slips during testing
Monitor for:
- Workpiece movement or slip
- Changes in vacuum sound (indicating leaks)
- Unusual resistance or binding
Stop immediately if:
- Workpiece shifts position
- Vacuum seal breaks
- You hear air leaking
Safe release procedure:
- Stop all cutting operations
- Support the workpiece with your hand
- Release vacuum smoothly (use inline valve or SYS-GRP Hub)
- Prevent sudden movement as vacuum releases
Why support is important: Workpiece may shift slightly as vacuum releases, especially if unbalanced or on an uneven surface.
Not Recommended Operations
Avoid:
- High side-load cuts without secondary restraint
- Prying operations against the seal
- Heavy machining on single-pod setups
- Operations creating large moment arms
Alternative: Add secondary mechanical clamps or stops for operations outside AnchorPod's optimal use cases.
Performance Tips
Maximize holding power:
- Keep surfaces clean and dust-free
- Use flat, low-porosity work surfaces
- Increase pod count for larger parts
- Verify gasket condition before each use
Improve workflow:
- Use inline valve or SYS-GRP Hub for quick engagement
- Pre-position pods for common workpiece sizes
- Keep gaskets and spacers organized in Systainer fitouts
