PURPOSE:To machine with plasm or laser beam the circular arc shape even the small graphic of straight line by moving the outputting end for machining within the plane crossing to the machining axis along the 1st and the 2nd cam and cam-follower whose phases are different. CONSTITUTION:Two sets of members 7, 8 moving with a spiral shape cam groove and a cam follower within the plane crossing orthogonal, to the axis of outputting end 21 of operating machine such the plasma torch and the laser gun are engaged to the outputting end 21 in the state that the phases are mutually made different by 90 degree, and operated at the same time. Because the outputting end 21 is smoothly moved at the case of either straight line or curved line without motchs, so even the small graphic can be precisely machined. |
