High-Energy Beam Contour Control for Automatic Breach Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control units in high-energy beam cutting machines are unable to automatically produce contours that result in contour breaches, leading to inefficiencies and increased costs, as they require manual deactivation and reactivation of contour breach avoidance functions for specific recesses.
Innovation Solution
A control unit with a function for detecting and automatically deactivating contour breaches, allowing defined contours such as I-slots and T-slots to be machined even if they would otherwise be omitted due to diameter mismatches, by averaging line movements to minimize errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the contour breach avoidance function is activated to prevent material removal errors, then manufacturing precision is improved, but productivity deteriorates because contours that must be produced are omitted
Solution Approach 1:
The control unit applies different quality levels to different contours by storing specific contours (e.g., I-slots, T-slots) with higher priority flags. When such contours are detected, the system locally overrides the general contour breach avoidance function, allowing material removal deviations to occur for these specific contours while maintaining strict accuracy for others.
Solution Approach 2:
The system performs preliminary classification of contours during program loading, identifying which contours require breach avoidance and which do not. This preliminary action allows the control unit to automatically deactivate breach avoidance for specific contours before machining begins, eliminating the need for manual intervention.
2Manufacturing precision
If the contour breach avoidance function is activated to ensure precise material removal, then manufacturing precision is improved, but ease of operation deteriorates due to manual deactivation requirements
Solution Approach 1:
The control unit automatically identifies contours requiring breach avoidance deactivation and performs the deactivation itself without operator intervention. The system serves itself by using its own detection capabilities to determine when to override the breach avoidance function, eliminating the manual operation step entirely.
Solution Approach 2:
The classification and deactivation decisions are made in advance during program loading rather than during machining operations. This preliminary action transfers the operational complexity from the machining phase to the programming phase, where it can be handled automatically.
3Adaptability or versatility
If the high-energy beam diameter is increased to handle material thickness variations, then adaptability is improved, but manufacturing precision deteriorates due to larger focal point diameter
Solution Approach 1:
The system applies different beam diameter requirements to different contours based on material thickness and contour type. For contours where breach avoidance is active, smaller beam diameters maintain precision. For contours where breach avoidance is deactivated (like I-slots and T-slots), larger beam diameters provide adaptability to thickness variations without compromising the overall result.
Solution Approach 2:
The control unit dynamically adjusts operational parameters including beam diameter and power based on the specific contour being machined and material thickness. This allows the system to optimize between precision and adaptability for each contour based on its specific requirements.

Function Achieved in This Case
Enables the automatic production of cutting gaps in contours that would otherwise be omitted, reducing workload and costs by allowing precise machining of complex shapes with minimal deviations, even when the laser focal point diameter changes with material thickness.
Implementation Method 1
a high-energy beam travels along a contour on a surface of the solid body facing the high-energy beam and herein produces a cutting gap

AI summary
In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.
