Increase machining performance with accurate tool-path computation
In the era of rapid digital transformation, computer-aided design (CAD) and computer-aided manufacturing (CAM) tools are inextricably linked and generally used together to simulate and visualize manufacturing processes. Highly accurate machining operations with minimized production defects are ensured by sophisticated tool-path computation algorithms based on exact geometric calculations.
The OPEN CASCADE CAM Library SDK delivers a comprehensive set of specialized algorithms that bridge the gap between design and manufacturing, enabling developers to create powerful CAM applications with precise toolpath generation and optimization capabilities.
This powerful SDK developed under the Open CASCADE Commercial Platform offers:
- A set of specialized data structures for 2D/3D modeling of toolpaths, contours and standard Boolean operations
- Unique algorithms for geodesic computations on complex surfaces
- Advanced numerical operations for offset and pocket operations on 3D geometry
