Contrary to initial persuasion, up to now there is no standard fieldbus but almost 50 different systems with deterministic characteristics regarding technical functions, application and popularity. But not every bus fits industrial use (fig. 1). Fig. 1: Encoder installed at a straightening machine in a sheet metal processing application. Multiturn absolute encoders with modular bus covers for c...

representations of future behavior ... usually a set of actions, with temporal and other constraints on them, for execution by some agent or agents.1 One motivation for automated-planning research is theoretical: planning is an important component of rational behavior—so if one objective of artificial intelligence is to grasp the computational aspects of intelligence, then certainly planning pl...

This paper discusses a systematic approach to implement the principles of Flat Pattern Analysis FPA for folding sheet metal products. The paper starts by highlighting the needs for the vehicular structure forming process with respect to the main production line requirements through using Quality Function Deployment QFD matrix. Additionally, the potentials of fold forming for sheet metal parts i...

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...

Sheet metal cutting using lasers is ubiquitous in the industry, and is used to produce everything from home decorations to excavator scoops. Metal waste is costly for the industry, both in terms of money, but also in terms of an increased environmental footprint. Tomologic develops a unique optimisation system that can reduce this waste drastically. This paper presents a CP approach to the Lase...

While the bending sequence planning has been intensively studied, design of the motion path of a sheet metal part in the bending operation tends to be ignored by researchers. Because during the bending operation, the space for maneuvering a sheet metal part is very small, collisions between the part and bending tools are likely to occur. When a robot is used to handle the part, the role of an a...

This paper aims at experimental and numerical investigation of springback behavior of sheet metals during Lbending process with emphasis on Stribeck-type friction modeling. The coefficient of friction in Stribeck curve depends on sliding velocity and contact pressure. The springback behavior of mild steel and aluminum alloy 6022-T4 sheets was studied experimentally and using numerical simulatio...
