| Abstract: | The effect of machining parameters such as the machine tool precision, the cutting force and the cutting dosage on the processing precision of the shafts parts fixed between two finials has been analyzed. The error model of the processing technology system is established. The computed method about the dependence of the elastic distortion of the parts on the cutting force are discussed. The relationship between the two kinds of cutting force, i.e., both of the rotary drive and the gear drive of the main axis of the unloading wheel between the two bearings, and the parts diameter tolerance is deduced. The machining process of trapezoid threads on the numerical controlled machine tool is calculated as an example. |
