The Challenge: Automation of a Special-Purpose CNC Machine
A leading manufacturer required an accurate digital representation of an existing special-purpose CNC machine to support automation integration. The original CAD data was unavailable, and traditional measurement methods were time-consuming and prone to inaccuracies. V3D Technologies provided a complete 3D scanning and reverse engineering solution to create an accurate Scan-to-CAD model for automation design and implementation.
The Solution: On-Site 3D Scanning of the CNC Machine
V3D Technologies performed on-site laser 3D scanning of the CNC machine using an ISO 17025 certified metrology-grade laser 3D scanner. Millions of accurate data points were captured to generate a highly detailed polygon mesh of the machine. The scan data was aligned to the coordinate system in VXmodel software and processed for reverse engineering.
