Vacuum hold-down systems
A well-built vacuum system is ideal for repeve cung of plywood and other sheet materials.
ShopBot oers several kits for full-table vacuum systems on our gantry tools.
Holding parts within the material
Tabs
Large parts may shi as they are cut free, leading to a small gouge or notch along the edge. Smaller
parts can be destroyed or even thrown across the room by the cuer.
There are two ways to handle this from within the soware. The rst opon is to create tabs, or leo-
ver “bridges” of material between the part and its surrounding area. Most CAM programs will have an
automated feature for this. The feature for VCarve Pro is shown here.
