Study on incremental forming for the fender of the car

The principles of incremental forming and the forming process of the fender are introduced. The effect of forming parameters on the metal forming is analysed. The improvement method of the parts forming quality is suggested. It is important that incremental forming technology is perfected. The forming wall angle θ and feed pitch p are the main process parameters in incremental forming of the fender. According to sine law, it will succeed in fender incremental forming in a single tool-path if the forming is carried out with an angle which is larger than the forming limit wall angle. In this study, we obtain the following result through calculation: θ=30°. When the feed pitch p increases, the process time decreases, and production rate and surface degree of roughness also increase. In general, the feed pitch is 0.25 mm.
