Not all designs are based on conventional forward engineering principles. For many reasons, the physical model, tooling or part itself maybe the only source of information available to design engineers. Without precise mathematical CAD models, it becomes extremely difficult to produce supporting documentation, inspection routines, and NC cutter paths for tooling. Whenever CAD data is unavailable to fully define a part’s geometry, Reverse Engineering is required.
Create high-quality engineering surfaces in CAD using 3D measurement data captured by PRO CMM ScanTRAK 3D laser scanner. Use the scan data to clean up, modify, sculpt and reconstruct surfaces to fully define a part’s geometry in various CAD/CAM environments. With the ScanTRAK handheld laser scanner, operators simply walk around large parts or assemblies and perform freeform scanning.
The handheld scanner is as simple to use as a paintbrush. By freely waving the handheld scanner over the part, surface measurements are rapidly acquired to produce dense point clouds, defining the part’s geometry. Because it is not physically attached to another measurement system, the scanner can be easily positioned to ensure exceptional coverage of the part. This unrestricted freedom and range of motion is achieved by using the PRO CMM Optical Tracker to constantly measure the position and orientation of the handheld laser scanner during the scanning process. The system ensures that all measurements are reported in a common frame of reference.
