Warning

Secure the material stock to the CNC machine by following the CNC manufacturer workholding guidelines.

FAILURE TO FOLLOW CNC MANUFACTURER WORKHOLDING RECOMMENDATIONS CAN LEAD TO DAMAGED PROPERTY, BODILY HARM, OR DEATH.

Verify that the material stock is properly secured by vigorously pushing and pulling against the workpiece in all directions.

View the Workholding Guide for examples.

Secure Workpiece With Machineable Brads

Drive plastic, composite, or wooden brads (small pointed fasteners) through the workpiece and into the wasteboard to hold the workpiece in place, similar to the screw down method.

Pros

  • Can be machined without damaging the tooling unlike metal screws or nails
  • Minimizes the risk of damage to thin, lightweight, and delicate materials
  • Provides a low-profile and unobtrusive holding solution without impacting Z Axis machineable height

Cons

  • May not provide sufficient holding power for heavy materials
  • Material thickness can be limited by brad length
  • Minimal or no reusability compared to other methods
  • Additional equipment required

Other Workholding Methods

Screw Workpiece Down

Predrill several pilot holes away from the machining area. Secure with screws appropriate for the material stock.

Clamp Workpiece

Use metal, wood, or plastic clamps to secure the stock from the top-down and/or sides.

Adhere With Double-sided Tape

Cover the flat base of the material stock with double-sided tape to adhere it to the CNC work area.

Adhere With Masking Tape and CA Glue

Cover both the flat base of the material stock and the CNC work area with tape and use CA glue to stick them together.

Jigs and Fixtures

Use custom-made jigs and fixtures to secure stock and for rapid cycle time when machining on multiple objects within the same operation.

Tack Down With Machineable Brads

Use machineable brads to secure the stock to the wasteboard, without risking tooling should collisions ever occur.

Use Vacuum Table

Hold down flat stock and release the material at a flip of a switch or automatically through MillMage.

Secure Workpiece in Vise

Securely mount a vise to the CNC work area and use the vise jaws to hold the material stock.

Workholding Optimizations

Workholding When Cutting Through Workpiece

Add custom tabs to keep objects in place when cutting through material stock.
