For the forming characteristics of cutting-extruding compound trimming, the influences of process parameters such as finishing allowance, fillet radius of main die and factors such as blank material, blank profile shape on finishing surface quality were analyzed by physical experiment, which provided a reliable reference for the actual production. The result indicates that finishing allowance and fillet radius of main die are the most important factors affecting the forming quality, and they have an interactive effect on the finishing process. The width of the bright zone of the cutting-extruding compound finishing surface is larger with good plasticity, small finishing allowance, small material thickness and large fillet radius of main die. Moreover, with the same parameters, parts with good plasticity are easy to get good surface quality, while parts with inner concave profile are easier to obtain a high quality than that with outer convex profile. And the surface quality of main die has a copy effect on the forming surface of parts.
