Abstract: A material machining center for the machining of workpieces of varying size and of various materials has a worktable supported by a base assembly. The worktable has a vacuum table for immovably holding the workpiece during the machining thereof. The machining center also has a gantry assembly movably mounted on the worktable, the gantry assembly further has a workhead assembly movably mounted thereon and a machining tool adapted for movement. The movements of the gantry assembly, the workhead assembly and the machining tool define a coordinate system having an X, Y, and Z axis, respectively. The machining center further includes a means for controllably inclining the worktable relative to the base assembly whereby dust and chips created during the machining of the workpiece fall from the workpiece to the floor.
