How to Use Deviation Analysis in Reverse Engineering
Over time, the actual use of a tool or part can outlive its documentation. Or, in production environments, a physical tool can be edited and adjusted to achieve required results. When it comes time to replace this customized part or tool, its print or CAD documentation no longer matches reality. So when a customer needs to accurately document or re-manufacture a legacy item of this kind, reverse engineering (RE) and geometry re-creation is essential.
Designing and Retrofitting
When a part is reverse engineered, designers work within the context of the larger system or device, because the new design must be flawlessly integrated. For example:
In advanced mechanical and aerospace industries, traditional reverse engineering in which only a CAD copy of the old component is developed is less effective than using a 3D model and performing deviation analysis as a final check. 3D re-engineering optimizes the component/sub-system design concerning new materials and the advanced manufacturing technologies often employed in such industries.
