Problem:
When engraving objects, the precision of the tool path is paramount as imprecise engraving can damage the objects. Usually, the engraving task is done on a known, flat surface by a CNC machine or laser. Therefore, our partners conducted a research project to investigate how to precisely create custom tool paths on an unknown curved surface.
年代olution:
The solutions deploys a PhoXi 3D Scanner model L from Photoneo and the application was developed in Rhinoceros and Grasshopper.
The solution consists of the following steps:
- PhoXi 3 d扫描仪的扫描工作
- Importing the captured point cloud to Rhinoceros
- 年代electing the engraving area, setting where and what to engrave, and creating a toolpath trajectory. Paths are generated automatically from text or vector graphics.
- Measuring tool path deviations with a laser scanner. The optimized tool path has a standard deviation of 0,0313 mm.
- Engraving
Discussion:
The PhoXi 3D Scanner has been chosen for this application because of its high quality of point clouds, wide scanning range, ability to identify workpieces in the workplace accurately and precisely as well as its ease of use.
This solution is part of a research project but it can be further developed and used in other areas where it is necessary to approach each working object in a different way.
