Abstract. This paper presents a new method for deep drawing process control. The new method consists in: i) using of a segmented-multiple moving drawbeads; ii) imposing an optimal reference trajectory for drawbeads position; iii) in-process control where controlled variable is chosen the amplitude of deviation G of the actual instant workpiece surface geometry with respect to the surface geometry during simulation and as manipulated variable is chosen the deviation h DB ' of the actual drawbeads position with respect to the programmed one; iv) periodical validation, calibration and updatation both of the control model and reference trajectory of drawbeads position; v) using a reduced order model of the complex system design. An experimental device conception and testing is presented. The results obtained using this device confirms the validity of the new proposed method for deep drawing process control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
