Technology: scanning with markers, reverse engineering
Location: RangeVision workshop
Equipment: RangeVision PRO 2M 3D scanner
Software: ScanCenter, CAD
Time costs: scanning and processing - 4 hours, building the models - 8 hours, drafting - 4 hours

RangeVision specialists performed 3D scanning and produced CAD drawings of router cutters to create a custom 3D model library for a furniture company. Now the client does not depend on foreign suppliers and can create new cutter profiles for woodworking.

The task was to scan three woodcutting bits and produce design documentation for their manufacturing. A lot of companies make their own digital archives of expendable tools in case of wear or rapid upgrades.

The cutting edge needed to be recreated with particular accuracy, so a professional RangeVision PRO 2M 3D scanner was used. To minimize the initial model creation time, RV engineers scanned all cutters simultaneously. They fixed the cutters to a flat surface with the use of modelling clay, and attached markers to the surface, as close to each other as possible, without intersection. After that, RV engineers scanned the bits step-by-step from all directions to obtain the objects faceted surface in .stl format, and used these scans to create a mathematical model.

The accuracy requirements for the CAD file were given by the client in advance, so RV engineers sent a comparison of the mathematical model and initial scans for the approval. This step is always performed for self-control but can be shared with the customer on demand. After the results were approved, the specialists produced the drawings.

Now the client can save money on purchasing wear susceptible tools, minimize the dependency on foreign suppliers and plan their production cycle more accurately.
