Telford based LVS Quality Measurement Services have recently taken delivery of a PRINCE 775 3D laser scanning system. Manufactured by ScanTech, the unit uses a combination of red and blue laser technology to provide very high resolution and highly detailed data capture.
The primary use of this equipment will be for high-resolution contactless measurement of components. In some cases, this will be as part of an inspection process such as dimensional reporting, but may also involve the reverse engineering of an existing item that has no existing CAD data.
The improved services that the new equipment will allow LVS QMS to provide include:
- Dimensional Reporting of parts without CAD data. Physical parts can be inspected without CAD data. Full dimensional reports can be produced on legacy parts that currently only have 2D drawings.
- Reverse engineering of existing components. This where there are no drawings available, but full CAD data is needed. This can apply to some re-shoring projects, where the overseas plastic processing company designed the component and manufactured the tooling. The use of scanning equipment is far less laborious than having to take hundreds of measurement using a CMM.
- Pre-Production Inspection of Tooling. Inspection of finished tooling to CAD can be completed before manufacture begins, ensuring that the tool is accurate and no areas have been missed or over machined.
- First Article Inspection. Inspection and verification of the newly manufactured part to the CAD design can be quickly generated, i.e., before full production commences.
- Trend Analysis, Statistical Analysis & ‘Golden Mesh.’ This involves the inspection of multiple parts to ensure the manufacturing process is reliable, repeatable and consistent. Full statistical analysis inspection can be completed, including Cpk, Ppk, Min, Max, Avg and Sigma values. If required, creation of a golden mesh or average part can then take place, providing a better model for purposes of product reverse engineering.
- Full Inspection to CAD with GD&T. This is the inspection of manufactured parts against CAD, showing critical dimensions and colour plots with a GO/NO GO scale that allows a production team to easily identify problem areas. GD&T (Geometric Dimensioning & Tolerancing) inspection can include product flatness, concentricity and parallelism.
- Digital Assembly. Multiple parts of an assembly can be individually inspected to ensure all parts will fit together correctly.
