With state-of-the-art solutions in the areas of test and measurement, technology systems, networks and cybersecurity, Munich-based technology company Rohde & Schwarz is one of the pioneers of a secure and interconnected world. Founded more than 85 years ago, the group is a reliable partner for its private and public sector customers worldwide.
HandyScan 3D for the Rohde & Schwarz plant in Teisnach
The Teisnach plant is a system supplier and mechanical and electronic manufacturing centre that is part of the Rohde & Schwarz plant network. This location is where body scanners, housings, printed circuit boards, television and radio transmitters, customer-specific radio communication systems, precision micromechanical parts and special electromechanical fabrications of all kinds are manufactured. As a contract manufacturer, manufacturing services are offered as part of a full range of services from product design and software development to after-sales service.
The measurement tasks are as diverse as the Teisnach plant and range from quality control for in-house production to complete reverse engineering tasks for additive manufacturing.
A flexible measurement system therefore had to be integrated into Teisnach, in particular in order to be able to complement the offer of the internal quality assurance service. The goal was to find a measurement tool that offers the greatest possible flexibility, both for measurements and applications: quality control, measurement of vehicle interiors for adaptations, control of complex free-form surfaces and use in additive manufacturing. High accuracy also had to be achieved at all times. In addition, control times had to be reduced and the creation of 3D models had to be simpler and faster.
The requirements also included measuring objects from the size of a 10 x 10 x 10 mm cube to the geometry of a jeep, with a required accuracy of up to 25 μm.
Creaform's HandySCAN BLACK Elite met all the requirements of the required measurement system and was therefore integrated to complete the range of quality assurance services at Rohde & Schwarz, where other fixed tactile and optical measuring devices are already in use. The decisive factor in choosing Creaform's 3D scanning solution was the wide range of applications it could handle, in addition to the following features:
- Ultra-precise and fast capture of complex free-form surfaces and large components, as well as rapid evaluation of scanned data. Thanks to non-contact scanning, highly sensitive and functional surfaces and contours are not damaged. However, this sometimes occurs during tactile measurements due to the contact of the probing ball with the component; For example, the probing point is visible on the gold components.
- Digitization of old or damaged stamping or injection molding tools for which there is no 3D model. Based on the scanned data, it is possible to create a CAD model and reproduce the tools.
- Flexibility, precision and ease of use and handling
- Thanks to the high scanning speed, the engineering effort has increased from one person-day to two person-hours for creating vehicle interior data.
Customer Testimonial
The HandySCAN 3D is regularly used in the Teisnach plant. Operators perform 3D measurements in the dedicated measurement room, directly in the workshop for component inspections, and at customer sites.
"Thanks to the mobility and high precision of the HandySCAN BLACK Elite, we are creating added value for our customers that would not have been possible with existing equipment. The Creaform system can be used flexibly. It represents a great improvement for us, especially for the construction of special vehicles. For example, we can now accurately and quickly measure vehicle interiors for adaptive designs. In addition, the scanner allows us to effectively control complex free-form surfaces. Creaform's service and assistance should also be highlighted. Overall, we are very satisfied," says Josef König, Head of Quality Assurance/Control Technology at the Rohde & Schwarz plant in Teisnach.
