Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tools for cutting and engraving slabs face limitations in flexibility, productivity, and efficiency, particularly when dealing with slabs of varying thicknesses and materials, leading to increased wear of cutting discs, generation of machining sludge, and reduced precision for thicker or harder materials.
Innovation Solution
A machine tool that combines a cutting disc and an engraving tool, both mounted on a support head, allowing for flexible operation and selective use based on slab thickness and material, with suction handling for automated separation and movement, and the ability to perform pre-cuts and incisions in a single pass, enhancing flexibility and productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the feeding speed of the cutting disc is increased to improve productivity, then the machining time is reduced, but the wear of the cutting disc increases significantly
Solution Approach 1:
The machine tool dynamically switches between cutting disc and engraving tool based on real-time requirements. The control system enables dynamic selection of the appropriate tool, allowing the system to adapt its cutting mechanism rather than being locked into a single static tool type. This dynamic capability resolves the contradiction by enabling high-speed engraving when productivity is prioritized while preserving cutting disc life when precision is needed.
Solution Approach 2:
The invention changes the fundamental operating parameters by introducing two distinct tool types with different operational characteristics. The engraving tool operates at higher feeding speeds (45-50 m/min) compared to cutting discs (≤15 m/min), while the cutting disc maintains lower speeds for precision work. This parameter differentiation allows the system to optimize for either productivity or tool life depending on the specific machining task.
2Reliability
If water cooling is applied to the cutting disc during operation, then the cutting performance is improved, but machining sludge is generated that requires disposal
Solution Approach 1:
The invention extracts the water cooling requirement from the overall machining process by introducing an alternative tool (engraving tool) that does not require water cooling. The engraving tool operates in dry conditions, completely eliminating sludge generation for engraving operations. This extraction principle allows the system to achieve cutting performance through a different mechanism that doesn't produce harmful byproducts.
Solution Approach 2:
The engraving tool serves as a disposable or easily replaceable alternative to the expensive, water-cooled cutting disc. While engraving tools may have shorter operational life, they eliminate the need for water cooling infrastructure and sludge disposal systems, reducing overall operational costs and environmental impact despite the tool itself being consumable.
3Device complexity
If a single cutting disc is used for all cutting operations, then the device structure is simple, but the adaptability to different slab thicknesses and materials is limited
Solution Approach 1:
The machine tool achieves multi-functionality by integrating both cutting disc and engraving tool within a single machine structure. The support head can accommodate either tool, and the control system manages both tool types, enabling the machine to handle diverse slab thicknesses and materials. This universal design allows one machine to replace what would traditionally require multiple specialized machines.
Solution Approach 2:
The machine dynamically adapts its tool configuration based on the specific machining requirements. The control system enables real-time switching between cutting disc and engraving tool modes, allowing the machine to optimize its performance for each specific task rather than being constrained to a fixed configuration. This dynamic adaptability resolves the contradiction between structural simplicity and operational versatility.
4Manufacturing precision
If the cutting disc is used for thick slabs, then the cutting depth capability is sufficient, but the feeding speed must be reduced leading to lower productivity
Solution Approach 1:
The invention segments the machining functions by separating deep cutting operations (cutting disc) from high-speed engraving operations (engraving tool). For thick slabs, the cutting disc performs the primary deep cut at appropriate speeds, while the engraving tool can perform preliminary or finishing operations at higher speeds. This functional segmentation allows each tool to operate in its optimal performance range, resolving the speed-depth trade-off.
Solution Approach 2:
The engraving tool can perform preliminary grooving or scoring operations on thick slabs before the cutting disc completes the full-depth cut. This preliminary action creates a pathway that reduces the effective cutting depth required by the cutting disc, enabling faster overall machining while maintaining the ability to handle thick materials.
