Thermal Expansion Limits in Aerodynamic Thermoplastic Housing Design
Accommodate thermoplastic thermal expansion using kinematic sliding mounts and recessed lap joints to prevent out-of-plane buckling and boundary layer tripping.
Stereo Photogrammetry
Meaning
The technique of using overlapping photographs taken from different positions to create accurate three-dimensional measurements of physical objects provides a non-contact method for surface analysis and structural monitoring. In manufacturing and quality control, stereo photogrammetry is used to inspect complex parts and ensure they meet strict dimensional tolerances.
Quality Inspection
This method allows for the rapid measurement of large surfaces without the need for physical contact, which reduces the risk of part damage. The resulting 3D models can be compared directly to CAD designs to identify any defects or deviations from the required specifications. This capability is particularly useful for inspecting fragile or high-value components.
Service Contract
Companies often outsource these measurement services to specialized providers under service agreements that define the required accuracy and reporting schedules. The service contract specifies the equipment to be used and the format of the final report, ensuring that the results are suitable for the client’s quality control processes.
Liability Boundary
The measurement provider’s liability is typically limited to the cost of re-performing the service if the initial results are incorrect. This limitation of liability is a standard clause in these service agreements, protecting the provider from secondary damages caused by incorrect measurements.
