Effect of Pin Tip Shape and Forming Conditions on Curvature in Peen Forming of Double-Curved Surface Using Rectangular Pin
Masaki Okada,Takahiro Ohta +1 more
TL;DR: In this paper , a new peen forming method, vibration peening, using a rectangular solid pin was developed, where the curvature radius Rx in the x-direction (short side of the pin) was smaller than the curvatures radius Rz in the z-direction, and regression analysis verified that Rx and Rz were approximately predictable under the unlearned condition.
