ABSTRACT:
A multi-axis machining apparatus including structure for positioning a workpiece in a precise and repeatable manner in relation to a tool bit. The multi-axis machining apparatus includes a first table forming a horizontally disposed upper surface and having an opening for mounting a first tool in an inverted position therein and for projecting a first bit upward through the opening and above said upper surface. The horizontal upper surface has first and second axes intersecting each other in perpendicular relationship and the opening is centered on a vertical third axis, intersecting said first and second axes in perpendicular relationship therewith. A fence structure may be attached to the carriage assembly for guiding movements of a workpiece along the upper surface of the first table. A second table assembly is attachable to the underside of the first table. A carriage assembly may be operatively engaged with the first table for moving the carriage assembly in a direction parallel to the second axis. The carriage assembly may include a carriage slidably engaged therein. A second tool having a second bit oriented in a downward position parallel to the third axis may be mounted to the carriage.
