REPLICATION OF AN EXISTING MODEL SHAPE USING LASER SCANNING – A CASE STUDY

Corina-Mihaela MATEI, Ioan BLEBEA

Abstract


Sometimes designers wish to use exact replicas of specific shape and configuration within their designs. In such reverse engineering situations, it is necessary to scan the existing shape as a first step. Once the shape is scanned, the data is used as input to the CAD/CAM system for generating a necessary tool path in duplicating the shape. This paper describes the requirements to complete the cycle from the original shape to the duplicate shape and illustrates the entire operational process with an actual example.

Key words: Reverse Engineering, 3D scanning, point cloud, mesh generation, surface reconstruction, CNC machining
