What Is Reverse Engineering:
The process of duplicating an existing component, subassembly, or product, without the aid of drawings, documentation, or computer model is known as reverse engineering.
Need For Reverse Engineering:
The original manufacturer of a product no longer produces a product
There is inadequate documentation of the original design
The original manufacturer no longer exists, but a customer needs the product
The original design documentation has been lost or never existed
Some bad features of a product need to be designed out. For example, excessive wear might indicate where a product should be improved
To strengthen the good features of a product based on long-term usage of the product
To analyze the good and bad features of competitors’ product
To explore new avenues to improve product performance and features
To gain competitive benchmarking methods to understand competitor’s products and develop better products
The original CAD model is not sufficient to support modifications or current manufacturing methods
The original supplier is unable or unwilling to provide additional parts
The original equipment manufacturers are either unwilling or unable to supply replacement parts, or demand inflated costs for sole-source parts
To update obsolete materials or antiquated manufacturing processes with more current, less-expensive technologies
Process Of Reverse Engineering:
- Identify the system’s components and their interrelationships
- Create representations of the system in another form or a higher level of abstraction
- Create the physical representation of that system
Important Points To remember Before to Start Reverse Engineering:
Reverse engineering enables the duplication of an existing part by capturing the component’s physical dimensions, features, and material properties. Before attempting reverse engineering, a well-planned life-cycle analysis and cost/benefit analysis should be conducted to justify the reverse engineering projects. Reverse engineering is typically cost effective only if the items to be reverse engineered reflect a high investment or will be reproduced in large quantities. Reverse engineering of a part may be attempted even if it is not cost effective, if the part is absolutely required and is mission-critical to a system.
Product Development By CAD Integrated Reverse Engineering Concepts:
Reverse engineering of mechanical parts involves acquiring three-dimensional position data in the point cloud using laser scanners or computed tomography (CT). Representing geometry of the part in terms of surface points is the first step in creating parametric surface patches. A good polymesh is created from the point cloud using reverse engineering software. The cleaned-up polymesh, NURBS (Non-uniform rational B-spline) curves, or NURBS surfaces are exported to CAD packages for further refinement, analysis, and generation of cutter tool paths for CAM. Finally, the CAM produces the physical part.
