Abstract
A system and method for removing particulate matter from an object being machined or having been machined. A vacuum tube is connected to a source of vacuum and has an intake end adapted to be placed in close proximity to the object being machined. In one embodiment the intake end has a slot such that the intake end can at least partially surround a machining tool. In another embodiment the intake end has standoff buttons that are placed against the object. The vacuum tube can have an inlet cone with a bellmouth shape. Ionized gas is directed at the area proximate the inlet cone and/or machining tool. A vibrator can also be used to vibrate the object.
