Machine Tool Trajectory Planning for Collision-Free Idle Moves

The patent applies preliminary action by pre-calculating and storing geometric models of machine tool components, workpieces, and clamping devices before the actual machining process. These pre-computed geometric representations are then reused during non-productive movements to quickly determine collision-free trajectories without performing complex real-time calculations, thus ensuring collision safety while minimizing computation time.

The patent uses copying by creating simplified geometric models (copies) of the actual machine tool components and workpieces. Instead of performing precise calculations on the complex real-world geometry during non-productive movements, the system uses these pre-created geometric copies to rapidly evaluate potential collision paths and determine safe trajectories, significantly reducing computational requirements while maintaining collision safety.

The patent applies segmentation by dividing the trajectory optimization process into distinct phases: identifying non-productive movements, evaluating geometric constraints using pre-stored models, and generating optimized paths. This segmentation allows the system to focus computational resources only where necessary, avoiding the need for complex continuous optimization algorithms throughout the entire machining cycle, thereby improving productivity without requiring excessive hardware complexity.

The patent implements universality by creating a geometric model database that serves multiple functions: collision detection, trajectory optimization, and machine tool configuration validation. This multi-functional approach eliminates the need for separate complex algorithms for each function, reducing hardware requirements while maintaining high productivity through efficient reuse of the same geometric representations across different operational contexts.

The patent applies preliminary action by pre-processing and storing detailed geometric information about machine tool components, workpieces, and clamping devices in a standardized format before machining operations begin. During non-productive movements, the system queries these pre-organized geometric databases rather than performing complex geometric calculations in real-time, ensuring collision-free movements while keeping computational complexity low.

The patent uses copying by creating simplified yet accurate geometric representations (copies) of complex machine tool components and workpieces. These geometric copies retain the essential collision-relevant features while reducing computational complexity, allowing the system to enforce detailed geometric conditions for collision safety without requiring excessive computational resources during trajectory determination.
