ABSTRACT:
An apparatus for reciprocatingly orbiting a saw blade with respect to a workpiece is provided. The saw blade is cammingly driven through a cam track to reciprocate the saw blade generally along a first axis to saw the workpiece. The saw blade is contemporaneously driven through a bearing to move the saw blade about a pivotal axis to space the saw blade from the workpiece when it is not being sawed. Cam tracks of irregular configurations are provided for improving cutting efficiency.
