The plan of NC turnmill compound machining process based on integrated procedure was proposed, a turnmill compound fixture equipment was designed. The load performance and removal performance of the wheel rim workpiece were analyzed according to the twodimensional plane clamping method, the clamping point position of wheel rim workpiece was determined. Using the principle of planar mechanism kinematic, one’s claw kinematics trace of turnmill fixture was analyzed, so that a quick clamping structure which could reduce the cylinder stroke was designed. This fixture device is convenient and reliable.
