This video features an interview with Juan Pablo Landeros, an optical scanner specialist, presenting the new tscan hw 2 portable optical scanner. Designed with portability in mind, the scanner is highlighted for its utility in various industries, particularly aerospace, enabling metrology, inspection, maintenance, and reverse engineering directly on large parts, even while mounted on aircraft. The tscan hw 2 offers high precision (20 micrometers within 1 meter, expanding by 15 micrometers per meter up to 4 meters guaranteed) and operates within a wide temperature range (5 to 40°C), suitable for non-controlled environments. Key differentiators include its use of photogrammetry without requiring coded targets, proprietary software for data acquisition and analysis, and the provision of local support, service, and calibration in Mexico. The video also demonstrates a quick, built-in daily verification process using a calibration bar and discusses the use of accessories to minimize stickers on scanned parts.
Summarizing the tscan hw 2 Portable Optical Scanner
0:05 Portable Optical Scanner: Introduction of the tscan hw 2, a portable optical scanner designed for multiple industries, emphasized for its portability in aerospace applications with large parts like aircraft wings.
0:53 High Precision for Aerospace: The equipment is necessary for the aerospace industry due to high requirements and tight tolerances, useful for identifying faults and damages in maintenance and repair.
1:32 Designed for Non-Controlled Environments: Unlike traditional laboratory measuring machines requiring controlled environments, the tscan hw 2 can be used in workshops, production areas, or even on the aircraft itself, operating between 5°C and 40°C.
2:47 Precision Specifications: The scanner offers a precision of 20 micrometers within 1 meter. Beyond 1 meter, the maximum permissible error increases by 15 micrometers per meter.
3:00 Large Measurement Range: Guaranteed precision is maintained up to 4 meters, allowing for scanning of very large pieces or assemblies like complete aircraft parts, although scanning can continue beyond 4 meters without the certificate guaranteeing precision.
3:51 Key Differentiator - Non-Coded Photogrammetry: A major advantage is being the first device to use photogrammetry on very large pieces without requiring coded targets, simplifying the scanning process by using only non-coded reference targets or accessories.
4:21 Proprietary Software: The scanner utilizes proprietary software for data acquisition, generating measurement reports, evaluations, statistics, and trend analysis.
4:48 Local Support and Service: Size provides local support, service, calibration, and maintenance in Mexico, eliminating the need to send the equipment abroad, despite being manufactured in Germany.
5:16 Metrology, Maintenance, and Reconstruction: The equipment can be used for surface inspection, metrology control, and also for reconstruction and maintenance of parts, including scanning used parts for comparison or design generation.
5:34 Reverse Engineering Capability: The scanner supports reverse engineering using proprietary software to generate designs from scanned prototypes or physical parts, especially useful when original designs are unavailable.
6:20 Comparison Options: Scanned data can be compared against 3D nominal drawings or a master part.
7:00 Minimizing Stickers with Accessories: Addresses a common client dislike by using plastic, magnetized accessories around the piece for placing targets, significantly reducing the need to place stickers directly on the part being scanned.
8:09 Piece Transformation Scanning: Some targets are still needed on the piece when scanning both sides for "piece transformation."
8:47 Quick Daily Verification: A significant differentiator is a simple, quick verification process using a calibration bar that takes only seconds to ensure the equipment is working correctly at the start of a day or batch.
10:12 Verification for Temperature Changes: The quick verification is recommended especially when moving the scanner between areas with different environmental conditions or temperatures.
10:44 Calibration Process: Annual calibration for audit reasons requires sending the scanner, panel, and calibration bars to a certified laboratory or having an engineer perform the procedure at the customer's facility.
