ABSTRACT:
A CNC machine for automatically re-indexing and machining multiple faces of a workpiece includes a traditional three-axis CNC machine and a gripper tool. A bar stock defining a first and at least a second workpiece is loaded within a first and a second vice on the table such that the first workpiece is disposed within the first vice and at least a portion of the second workpiece is disposed within the first and the second workpiece. The CNC machine machines the first face of the workpiece within the first vice. Next, the CNC machine grasps the first workpiece using the gripper tool removably disposed within the spindle. The first workpiece is re-indexed and is loaded into a third vice disposed on the table and the next face of the first workpiece is machined. A support rack is preferably used to support a portion of the bar stock overhanging the table.
