Beschreibung
Zusammenfassung:	Compound machining apparatus comprises five axial kinetic coordinate systems that can be controlled simultaneously, three axes of which are linear moving axes X, Y, Z and two axes of which are rotary axes B, C, with one axis of the five axes provided with a tool rotating function. The apparatus is equipped with a cutting tool 51 and a friction stir welding tool 52. The device current value observed when a large diameter portion of the tool 52 contacts the work object is set in advance, and by observing the torque current of the rotary shaft of the tool 52 during friction stir welding, the insertion depth of the tool 52 can be controlled by maintaining the observed torque current above the preset current value, thus providing a good weld. The single apparatus performs both the cutting and the welding, reducing equipment cost, installation space, plant area, lead time and production cost.
