Surface Engineering Applications

There are many applications where surface contact during measurement is not an option; wet films, soft materials are typical. There are others where the surface does not allow for contact measurement due to designed features such as recesses.

The 2D and 3D non-contact measurement solutions from CyberTECHNOLOGIES GmbH have been used in many industries around the world to provide solutions to these and other issues.

With options in light sensor technologies to accommodate soft and hard materials, translucent and transparent films, highly reflective and non-reflective surfaces, most samples can be catered for.

A variety of platforms enable differing solutions when presenting samples to the sensor. Flat beds to 1.8 m square have been supplied, systems to measure round objects, solutions for measuring both sides simultaneously, as well as multiple sensor configurations.

The SCAN CT software suite covers all aspects of setting up, scanning, data acquisition, analysis and reporting, with the additional ASCAN software to provide test and analysis automation for the production line.

3D Additive Manufacturing – Loughborough University

“3D Fashion is a collaborative project based at Loughborough University, and is working to develop additive manufactured garments and textiles on a commercial scale. In order to improve the tactile properties of these textiles, the project has been experimenting with methods that reduce the rough nature of the 3D printed surface. With the use of the CT 100, we have been able to quantify the resultant surface finishes of these processes, as well as being able to clearly visualise the textures created on a detailed level. With only a small amount of training this could be achieved quickly and easily, and has allowed us to evaluate and optimise a complete finishing process.”

cyberTECHNOLOGIES CT 100 Non-Contact Profilometer

The system used in this project was the CT 100 compact, high resolution non-contact profilometer. It was fitted with a P-CHR-1000 confocal white light sensor with a resolution of 0.035 μm, measurement range of 1000 μm, and a working height above the surface of 20.8mm. The scanning, data acquisition and reporting were automated using the AScan software.

Key points:

  • 35 nm resolution, 1 mm measurement range for optimum scanning
  • Confocal white light sensor for excellent response from bright white surface
  • Surface roughness assessed using methods to international standards
  • Motorized z-axis for automated height changes
  • Range Extender feature to extend height measurements
  • 3D graphics provide quality surface images for reporting
  • ASCAN automation software allowed repeated scan, analysis, recording and image saving
  • High resolution camera fitted to assist with setting up and image grabbing

 

Case Study: Roughness Measurement of an Impeller Component

The CT products are ideal for the assessment of surface issues on complex shapes such as impeller blades. The Confocal white light sensor technology means that the objective scans above the component surface, so clearing higher features while allowing the measurement of surfaces below even in recesses. In addition, they are suited to measuring materials which are highly reflective. The resultant data set can be used for feature measurement as well as well as surface roughness evaluation. This can be exported and compared with CAD models. The systems can be fully automated for production environments as well as one-off measurements.

Key points:

  • Confocal white light sensor suited to required measurement range
  • 300 mm square table to accommodate full range of customer component sizes
  • Step and repeat function to assess key areas only
  • Library of measurement parameters to international standards including ISO 25178
  • Parameter analysis fully automated using ASCAN software
  • Filters to separate flatness from surface roughness

 

Case Study: Flatness of Hard Disk Dive Component

Flatness of components in the hard disk drive assembly is crucial to prevent the read/write heads impacting with the disk surfaces. A good understanding of flatness will assist in the control of the production process.

In this application a free standing cyberTECHNOLOGIES CT 300 system has been used in a production environment, enabling the operator to place components onto the stage, and then take advantage of the of the automated capabilities of the CyberTECHNOLOGIES software to correct for placement error, then scan, acquire and process the data according to the required tolerances.

The results are available in 3D and 2D profile, with a full library of height, flatness, and surface roughness parameters which are selectable depending on the application. The results can be exported in several formats, and colour warning indications can be shown according to the required tolerances.

Key points:

  • Confocal white light sensor
  • Platform sized to accommodate several devices simultaneously
  • Scanning and analysis fully automated for rapid unattended scanning
  • Statistical Process Control reporting
  • Floor standing option for production environment
  • Expandable to allow for second sensor type
