Abrasive water jet milling (AWJM) is a new way to perform controlled depth milling especially for hard materials, but it's not yet enough reliable because of large variety of process parameters and complex footprint geometries that are not well mastered. In order to master the milling device in AWJM, a deep study on the footprint of a single path of the cutting head should first be considered. The flow of the AWJ and the distribution of abrasive particles coming out of the jet are related to the profile measured on the footprint. In this study, experiments were made on titanium alloys specimen to compare several theoretical models to the measured profile of the footprint. This study establishes new models to fit the incision profile taking in consideration the behavior of the abrasive particles impacting the workpiece.Key words: Abrasive waterjet milling, incision, titanium alloy, process parameters, Gaussian model. Nomenclature:a maximum depth parameter (mm) b width parameter (mm) b0.5 width at half of maximum depth (mm) b1 width parameter of first Gaussian part (mm) b2 width parameter of second Gaussian part (mm) 1-IntroductionAbrasive water jet (AWJ) acquired a great technological progress in the last decades. Its popularity has changed considerably thanks to its high pressure joined to the flow of abrasive particles allowing the cut of any type of material. AWJ is a non-conventional machining process in which a mixture of abrasive particles and water at very high pressure is converted into a high velocity jet to cut various materials that can range from brittle to ductile materials. The water jet cutting is considered as a very efficient manufacturing process involving small amounts of heat transferred to the workpiece. Thereby, metal parts made by AWJ process does not change the crystal structure usually caused by the heat generated with other methods of material removal such as laser cutting, EDM (Electrical Discharge Machining), milling machining... The AWJ has become an emerging technology with versatile features.Controlled depth milling appeared in the early 1990s and is intended for the production of pockets. Until now this process has not yet been mastered, especially for hard materials. In order to comprehend the milling of pockets in AWJ, milling incisions (representing a single path of the cutting head on the workpiece) should firstly be studied. Several works were established to investigate this technology, F. CENAC studied controlled depth milling on Composites and aluminum alloys [C1] [CC1], and G. FLOWER worked on Titanium alloys [Fo1]. In their studies masks were used to avoid irregularities in the bottom of the milled pocket. In the case of maskless pocket milling in AWJ, a precise study on the impinging water jet is required to understand the mechanisms of abrasive and water flow machining and their impact on the workpiece.Article 039-pp-9 474Research in Interactive Design -Vol. 4 F. CENAC showed in his studies [C1] that the velocity profile of water particles going out of the cu...

“…VC is used during the planning phase of production lines in order to improve their layout in a prototypedriven fashion while avoiding the hardware cost of physical prototypes. The concept of VC went hand in hand with the development of first computer-aided design techniques and was initially named "soft-commissioning" by Auinger et al [5]. Over time, a couple of commercial software solutions for VC emerged.…”

Automation in micro-optical assembly is an emergent, but steadily growing field of research. To advance the optics industry's efforts in this regard, several methods that aid optics engineers with development and deployment of assembly processes have been proposed. However, it is still a non-trivial and time-consuming task to design efficient work orders that consider movement characteristics of integrated robotic assembly systems.In this contribution, we present an approach to combine wellinvestigated symbolic planning algorithms, semantic modelling techniques and 3D simulation-based virtual commissioning to generate optimized work orders for automated micro-optical assembly and thereby help to overcome the difficulties of manual process design. Our approach is a good example for the efficiency of the eRobotics concept and demonstrates how its systematic application can resolve practical problems with existing approaches.Results indicate that our approach to automated planning is, by enabling a formal definition of quality metrics for action sequences, not only faster but also usually superior to manual generation of work orders.

“…Emulation is also considered as a certain phase within testing process of a controlled system. The development of a complex system (eg a container terminal), which is controlled by a separate control system (eg a TOS), may include one or more of the following phases, which aim to test the system during different design stages (Auinger et al, 1999).…”

Container terminals are struggling with a continuously increasing volume and increasing performance demands. As space is typically limited, terminals are searching for solutions to increase throughput capacity without expanding their physical footprint. Furthermore, they aim to increase their productivity on vessels in order to be able to handle bigger ships with larger call sizes in the same time frame. A terminal operating system (TOS) plays a major role in today's terminal operations, as it supports planning, scheduling and equipment control. Recently more and more tasks are performed by the TOS. These tasks need to be well-tuned to the operation (such as stowage planning, grounding decisions and equipment dispatching) in order to reduce cost and risk. In this paper, we present a meanwhile proven, safe and inexpensive approach to test and tweak the TOS and train operators on an emulated virtual terminal. This novel approach in the field of container terminals has been successfully applied during the previous 3 years at over 15 container terminals.
