How do you hold down thin, flexible plastic sheets on a CNC router?

Question

Accepted Answer

A multi-zone vacuum hold-down table is the standard method for sheet plastics. Thin acrylic, expanded PVC, and HDPE sheets tend to bow upward in the center when clamped along the perimeter. Vacuum suction draws the entire surface area flat against the spoilboard, eliminating internal sheet vibration, stabilizing small parts, and ensuring consistent cut depths across the entire table.
