Optimized Bending Sequences of Sheet Metal Bending by Robot
In the present study, a method is proposed which generates bending sequences of a sheet metal part handled by a robot. If parts are handled by a robot, the best grasping positions for each bending and the number of repositions must be indicated in advance. Using the proposed method, feasible bending sequences with grasping positions are obtained and the sequences are sorted in order of the numb...
متن کاملSheet Metal Bending : Generating Shared Setups
Contemporary process planners for sheet metal bending solve the process planning problem for individual parts. Quite often, many di erent parts can be produced on shared setups. However, plans generated by current process planning systems fail to exploit this commonality between setups and try to generate optimal setups for individual parts. In this paper, we present an algorithm for multi-part...
متن کاملSheet Metal Bending Operation Planning Using
A large number of manufacturing operation planning problems can be formulated as state space search problems In case of sheet metal bending operation planning processing a search node involves extensive geometric reasoning Such computation intensive node processing limits the number of search nodes that can be expanded in a reasonable amount of time making it di cult to solve real life operatio...
متن کاملAutomated Process Planning for Sheet Metal Bending Operations
In this paper, we describe a generative process planning system for robotic sheet metal bending press-brakes. This process planning system employs a distributed planning architecture. Currently, our system consists of a central operation planner and three specialized domain speci c planners: tooling, grasping, and moving. The central operation planner proposes various alternative partial sequen...
متن کاملConstraint-based process planning in sheet metal bending
The majority of research dealing with computer-aided process planning of sheet metal bending approaches this problem as heuristic search. Since relevant engineering knowledge mostly consists of declarations that prohibit collisions and just a handful of generative rules, there are no useful means to drive these heuristics. In order to find a new way, we have made experiments with a constraint-b...
