Gain insight into 3D testing and inform yourself about possible applications of optical metrology for materials testing and testing of components and individual parts with simulation verification.

GOM systems are non-contact and material-independent measuring systems based on digital image correlation (DIC). In contrast to strain gauges, accelerometers, transducers or extensometers, the sensors, which are measuring without contact, capture geometries and three-dimensional displacements and deformations, for example, in tensile tests. In this process, capturing static and dynamic deformation is not only based on individual points, but on full-field measurements. The results allow users to determine input parameters for simulation. Simulation models can also be compared with measuring data in order to choose the right material and improve geometry and manufacturing processes. This speeds up product development, while increasing safety and durability of the components at the same time.

This station will be supported by ZwickRoell: It will be possible to see a real installation with ARAMIS sensor in combination with one of their machines.

ZwickRoell is the world's leading supplier of materials testing machines. Our materials testing machines are used worldwide in R&D and quality assurance in more than 20 industries. For more than 160 years, ZwickRoell has stood for reliable test results, excellent service, and quality and reliability in materials and components testing.

When it comes to complex components with internal structures, many measuring procedures reach their limits.

For this reason, GOM has developed a computer tomograph that is specifically designed to meet the metrological needs of users from industry for nondestructive testing. Increasingly complex parts, which are manufactured in additive procedures, for example, are pushing up the demands placed on measurement technology by industry.

As an industrial computer tomograph, the GOM CT delivers high-precision and repeatable measuring data via X-ray inspection. The GOM CT scans transparent parts or complex injection-molded components with internal structures that cannot be measured without a destructive method. Applications include first article inspection, tool release or the inspection of medical components.

In concepts such as PLM (Product Lifecycle Management), as much process and part information as possible is gathered in the form of PMI (Product Manufacturing Information) to ensure a comprehensive and company-wide management and control of production chains. GOM supports interfaces for digital transfers of inspection features. Quality criteria and datum systems that were implemented by a semantic construction into the CAD can be transferred digitally and evaluated in a context-sensitive way. Since the inspection plan is generated directly during the CAD import, additional work-intensive programming is not necessary.

This station will be supported by EnginSoft with their software named CETOL: It will be highlighted how the importance of using PMI can be integrated into the tolerance analysis chains.

EnginSoft is one of the leading technology transfer companies in the field of Simulation Based Engineering Science (SBES). The fully intergrated 3D tolerance analysis software tool provides the invaluable insight needed to confidently release designs for manufacture and inform the selection of appropriate tolerances to achieve your variation goals efficiently. Fixing assembly problems late in the design chain or avoiding them long before production, all while saving money.

CETOL 6σ enables designers and engineers to easily address multi-dimensional problems, using their native CAD geometry. This unique method allows you to receive immediate analytical feedback, utilizing the easy-to-use modelling, analysis and reporting components. The user is guided through the tolerance analysis and optimization process whilst being informed about missing or erroneous data.

GOM is the main actor in the validation of simulation processes. The GOM Inspect software is currently used with the dual purpose of evaluating in advance the dimensional quality of a simulation and in an extensive manner in the dimensional verification of a prototype made in accordance with the simulation itself.

This station will be supported by Moldflow provided by Prisma Tech.

Prisma Tech is a solid and reliable partner for companies that need innovation in the design and production processes. The main goal is to implement technological solutions, in particular for the definition of style, engineering, prototyping and production simulation processes.Plastic Injection Moulding Features.

This station will be supported by Overmach: It will be possible to see a real installation with a rapid prototyping machine in action.

Overmach was founded in 1978 by the strategic decision of the Company Salvatore Marchelli, which operated in the tooling and machine tools sector since 1817. Nowadays OVERMACH Group is specialized in the sale of chip removal CNC machine tools for metal working, either new and second-hand, along with before and after-sales service all over the Italian territory.

Rapid prototyping machines represent the current technologic frontier for knocking down the time-to-market of a wide category of industrial products. In order to be present in this new and important sector, this Division was created on purpose, with a suitable structure for satisfying the high level technology request, dealing with 3D printers Stratasys.
