AI-supported planning of tool paths in CAM systems.

Gesture description using voxel representation.

The VR application uses a stereo screen to create the 3D effect. Gestures can be input using the tracking stylus. The captured positions and orientations of the input device are displayed in real time in the VR application, so that direct feedback on the entered gesture can be given. The system then converts the data into a voxel representation, from which the artificial intelligence finally recognizes the essential features of the gesture. The software calculates the tool path based on the recognized features. This can be used, as in conventional CAM systems, to simulate, examine and carry out the process, the IPT researchers note.

Successful finish machining of test components.

For the test, the team successfully used the "CAMStylus" system to plan a finishing operation on a real test geometry of the WBA Aachen Tool and Die Academy GmbH. The project results pave the way for further research and development projects with industry partners. They are now being presented in scientific publications and conferences and will be further developed in the various user communities of the IPT with partners. An initial publication entitled "Intuitive toolpath planning in computer-aided manufacturing systems using artificial intelligence in a virtual reality environment" will be published this year at the 17th CIRP-ICME conference. The project partners also include Moduleworks GmbH, which coordinated the project, and Schneider Digital Josef J. Schneider e. K.

The research project "CAMStylus - Development of an AI-supported Virtual Reality Solution for the Intuitive Operation of Computer-Aided Manufacturing Systems" is funded by the Federal Ministry of Education and Research (BMBF) (identifier: 01IS22006D).
