A Perth based customer approached LSA to perform high precision laser scanning and reverse engineering on some mill throat liners for casting.
Using our portable CMM with integrated scanner LSA are able to provide laboratory accuracy with complete portability. Traveling to the clients place of business LSA undertook scanning of 4 large mill liners which were extremely worn. Data capturing was completed inside a day and the data was taken back to our office for post processing, meshing and cad modelling.
Cad models were made using Solidworks and a final Metrology verification report was supplied so the client is able to approve that the 3D model supplied meets the original data within a specified tolerance.
This is LSA standard delivery requirement’s for all reverse engineering projects. Either the client or LSA will CAD model the item, then an analysis of the overall accuracy of the 3D file is reported in a easy to ready visual report. (pictured)
This process is also used to provide wear analysis, failure analysis and condition monitoring of assets regardless of the items physical location.
Following are common reasons for reverse engineering a part or product:
- OEM of a product no longer produces a product
- Missing drawings or critical information
- 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
