“…Various techniques have been used to monitor, model, optimize, and control servo press motion to minimize defects [3][4][5][6][7]. As an example of the benefits and key considerations when designing a press motion profile, pulse motion named JIM-FORM was developed for improved deep draw forming.…”

Servo presses enable new types of forming motion profiles that can be used to stamp difficult materials, such as high strength steels. This paper presents an application of Bayesian statistics to intelligently select which motion profile maximizes the expected utility given the properties of the incoming material. Bayesian logistic regression was used in conjunction with expected utility to estimate manufacturing returns, which can be used to make informed process decisions. A use case is presented, which demonstrates that the Smart Forming Algorithm can increase expected returns by more than 20%.
