The selection of the power spinning parameters has a direct influence on the dimensional precision of the formed products. Through taking the tin-bronze connecting rod bushing after power spinning as the object

selecting thinning rate

working angle of wheel

fillet radius of wheel and feed ratio as factors of optimization experiment as well as taking difference of wall thickness and the expanding diameter of connecting rod bushing after spinning as the evaluation indicator

orthogonal experiment was designed and the experiment data was analyzed.The power spinning parameters were optimized through the Taguchi method. And the optimized parameters were presented as follows: the thinning rate of 30%

the working angle of the rotary wheel of 15°

the radius of the rotary wheel of 10 mm

and the feed ratio of 0. 5 mm/r.
