Automated 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 کاملAutomated Tool Selection for Computer-Aided Process Planning in Sheet Metal Bending
Bend sequencing and tool selection have long been the main hurdles for achieving automatic process planning for sheet metal bending. In this unique process, the complex shape and position transitions of workpieces make it hard to obtain a collision-free operation plan. The time-consuming involvement of human experts is often required to solve more complex problems. This paper presents a tool se...
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...
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 کاملProcess Information Model for Sheet Metal Operations
The paper extracts the process parameters from a sheet metal part model (B-Rep). These process parameters can be used in sheet metal manufacturing to control the manufacturing operations. By extracting these process parameters required for manufacturing, CAM program can be generated automatically using the part model and resource information. A Product model is generated in modeling software an...
