ATOS sensors are ideally suited to the measurement of complex freeform surfaces and are increasingly used to measure the airfoils found in many types of power systems, from aero to power generation engines. ATOS 3D measuring data helps assessing airfoil performance and manufacturing variability. GOM Software 2017 supports new engineering workflows and functionalities and a new inline product answers the need for digital, automated factories.
Manufacturers of large structural castings for aerospace and power generation are benefiting from using manual and automated ATOS technology to ease capacity constraints in their measurement and inspection processes. Automated measuring processes help improving measurement and inspection cycle times on large structural components, where traditional processes are often slow and labor intensive. 3D metrology accelerates maintenance, service and upgrading of turbines: by identifying faulty spots or parts to be replaced, controlling the material coating as well as inspecting the post-processing.
Quality management and assurance are steadily gaining importance in industrial development and manufacturing. Decentralized component production by suppliers means that tight specifications have to be met in order to guarantee problem-free final assembly and produce a high-quality product. The ATOS optical digitizing system from GOM is tried and proven in the inspection of metal sheets as well as body-in-white analysis. With the sensor and software all developed in-house, GOM has created a comprehensive solution and secure workflow for the sheet metal inspection process, enabling surface and sharp-edged features to be verified with one system.
Modern development processes harmonize the vision of perfect design with economic and functional requirements. Innovative design concepts must be quickly translated into digital data for CAD/CAM software. Since 2004, GOM has been meeting regularly with design studios from automotive OEMs to discuss actual developments specifically for the design studio application.
During try-out of sheet metal forming tools, the complex interaction between material, tool and press machine needs to be mastered as quickly as possible. GOM's optical metrology systems enable fast inspection of the shape and dimensions of sheet metal parts.
In addition, the GOM ARGUS system for forming analysis detects material defects that occur during the forming process even before they are visible to the human eye. Objective root cause analysis significantly reduces iterations until tool buy-off.
Optical 3D metrology has been established in biomechanics for dynamic analyses of implants and prostheses, but also of bones, tendons and ligaments. During load and fatigue tests, the mechanical properties of biomaterials and their behavior under load are analyzed. Sporting goods manufacturers use GOM systems to analyze new materials and to develop innovative products. Furthermore, GOM’s 3D scanner provide full-field geometric data to inspect medical devices made of plastics and for further processing in CAD/CAM processes in dentistry.
In casting and forging processes, 3D metrology supports and speeds up all phases in sand, pressure die and investment casting: from pattern and die construction to mold and core making, right through to first article inspection reports and optimization of CNC machining. With the ATOS optical 3D coordinate measuring system, the complete surfaces of patterns, tools, molds, cores, and cast and forged parts can be measured - non-contact and regardless of the object size. Full-field surface measurements guarantee faster sampling inspection and targeted tool correction, thereby reducing production lead times. For production accompanying quality control, both the measurement and the entire evaluation process can be automated.
3D optical metrology methods are today increasingly used in many civil engineering applications. Optical measurements support an accurate understanding of the material deformation behavior of concrete and composites, for example, which is essential for the determination of material parameters and to set up a reliable material model as input in numerical simulations. Components and structures are measured optically and the full-field results enable a complete evaluation of the objects surface for the verification of numerical models, failure prediction and performance and structural safety analysis.
GOM takes care of education and training on many different levels. From basic knowledge about how to operate a system over theoretical knowledge about computation principles and software handling to deep specialized application skills, there are all needed training courses available. In addition to the classroom courses, GOM offers training webinars and videos teaching specific workflows and background information about software functions and concepts. Furthermore, GOM offers comprehensive education packages for theory and practice lessons at schools, higher education institutes and universities.
On a regular basis, GOM organizes industry-specific workshops for the sheet metal forming, injection molding and casting industries as well as for materials and components testing. The global GOM network established these international event series to transfer process-related and metrological knowledge to design engineers, tool makers as well as specialists from production and quality assurance around the world.
For users who process and evaluate 3D data, GOM provides free software packages for 3D metrology and 3D testing.
3D CAD-based inspection today replaces 2D drawings, with a trend to include all tolerance information directly within the CAD model (FTA / PMI). The inspection language must be understandable for metrology experts but also for CAD engineers, tool & mold and manufacturing departments. GD&T / GPS fulfils this criteria and offers an economic quality control.
OEMs and suppliers split design, development and production facilities over many countries and continents. Thus, organization of process and product quality must work across different nationalities today. The rollout of certified metrology systems and of parametric software enables traceable inspection results and help to sustain product quality within the global supply chain.
The reorientation from tactile to optical, full-field measuring technology is due to the completeness and comprehensibility of the results provided. The non-contact and full-field coordinate measuring technology enables to achieve a density of information that is not possible by tactile means.
For training, the global GOM network transfers process-related and metrological knowledge to design engineers, tool makers as well as specialists from production and quality assurance around the world.
Optical metrology analyzes the mechanical properties and deformation behavior of all kinds of materials in various test scenarios. GOM's ARAMIS systems can be integrated into existing test environments, test benches and universal testing machines. The non-contact sensors measure full-field 3D displacement and strain under mechanical or thermal load. Thus conventional extensometers and strain gauges can easily be replaced by GOM's real-time 3D surface deformation analysis systems.
Knowledge of material properties is important
Optical measuring techniques are used to determine part shape, part behavior and material properties. These data typically serve as parameters for numerical simulations and contribute to improve the results of finite element simulations. The 3D measuring data generated by GOM metrology systems are also used to validate simulation results in prototype and component testing in order to precisely optimize simulations. The GOM Software 2017 supports extended functionalities for the validation of numerical simulations, such as FEA result import, alignment, mapping and comparison of 3D shape, displacements and strains.
Industrial production processes require automated measuring cells for higher throughput (more parts in less time, better planning) and higher repeatability (process safety). As a one-source provider for industrial measuring sensors and parametric inspection software GOM´s automation team opens the way to a uniform and centralized part inspection management with parametric and traceable inspection workflows. GOM technology can be integrated into complex production environments using standardized industrial interfaces.
The aerospace industry increasingly relies on lightweight materials and new material combinations. These materials are analyzed intensively during load, fatigue, structural and aerodynamic testing. Non-contact sensors are fully integrated in test stands and provide information about the behavior of components such as buckling or structural vibration of an aircraft. The measurement data optimize simulation and design processes and thus increase aircraft safety.
To speed up design and simulation, the automotive industry relies on optical measuring systems. Applications include crash and impact tests as well as climate chamber, wind tunnel and fatigue testing. Online measuring and evaluation supports dynamic deformation analysis during function and safety tests for components. The evaluation of torsion, bending, displacement, velocity and acceleration factors makes it possible to analyze safety risks, part lifetimes, creep and aging processes as well as visual appearance over time and usage. Optical metrology therefore detects bad part behavior and assists root cause analysis, e.g. disturbing noises, vibrations and complex movements, delivering specific feedback for fast design/product improvements.
3D digitizing saves time and costs during tool and electrode production and maintenance. Process control at an early stage reduces correction loops. Nominal/actual comparison serves to control the individual steps during CNC processing of tools. In try-out, 3D measuring data allows for a specific tool correction and a lower material input. The verification of FE simulations serves for knowledge building and guarantees an increased reliability of numerical simulations.
