A machine is disclosed for cutting a workpiece made of styrofoam or like material. The machine includes a frame having a generally planar base adapted to support the workpiece. A rotary cutter is supported above the workpiece and is rotatably driven about an axis perpendicular to the base of the frame. The rotary cutter is mounted to a carriage which is moveable on a slide in a first direction parallel to the base of the frame. The slide, in turn, is movably mounted to the frame in a second direction which is also parallel to the plane of the base but perpendicular to the first direction. The rotary cutter is also movably mounted to the carriage in a direction generally perpendicular to the plane of the base so that the cutter is moveable along all three or orthogonal axes. The cutter includes a plurality of radial bores which are fluidly connected with an axial bore in the cutter. A source of vacuum is applied to the cutter axial bore so that debris caused during the cutting operation is evacuated by a vacuum source through the cutter and to a debris collection area.

Abstract

A machine is disclosed for cutting a workpiece made of styrofoam or like material. The machine includes a frame having a generally planar base adapted to support the workpiece. A rotary cutter is supported above the workpiece and is rotatably driven about an axis perpendicular to the base of the frame. The rotary cutter is mounted to a carriage which is moveable on a slide in a first direction parallel to the base of the frame. The slide, in turn, is movably mounted to the frame in a second direction which is also parallel to the plane of the base but perpendicular to the first direction. The rotary cutter is also movably mounted to the carriage in a direction generally perpendicular to the plane of the base so that the cutter is moveable along all three or orthogonal axes. The cutter includes a plurality of radial bores which are fluidly connected with an axial bore in the cutter. A source of vacuum is applied to the cutter axial bore so that debris caused during the cutting operation is evacuated by a vacuum source through the cutter and to a debris collection area.
