Innovation Solution
A CNC system and apparatus where the workpiece is maneuverable on an X-Y table, allowing it to be moved between stationary tooling stations, with off-the-shelf power tools adapted into CNC tools using encapsulation and actuation modules for enhanced functionality and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized tool is maneuvered over the working area in state-of-the-art CNC tables, then the machining process can be performed, but the versatility and precision are limited compared to having multiple stationary tooling stations with movable workpiece
Solution Approach 1:
Instead of moving the tool over the workpiece (conventional approach), the patent inverts the system by making the workpiece movable and the tools stationary. The workpiece is mounted on a movable platform that can be positioned under different stationary tooling stations, fundamentally reversing the traditional CNC architecture to achieve greater versatility.
Solution Approach 2:
The working area is divided into multiple independent tooling stations, each equipped with different tools for various machining operations. The workpiece can be sequentially positioned under different stations to perform multiple operations, effectively segmenting the machining process into discrete stations.
2Manufacturing precision
If manual manipulation of workpieces is used in state-of-the-art CNC machines, then the machine structure can be simplified, but the precision and efficiency of moving substrates between tooling stations deteriorates
Solution Approach 1:
The workpiece platform is designed with dynamic positioning capabilities, allowing it to move precisely between different tooling stations along defined axes. This dynamic movement system replaces manual manipulation while maintaining the ability to adjust and position the workpiece with high precision under each stationary tool.
3Ease of manufacture
If off-the-shelf power tools are adapted into CNC tools, then the cost and complexity of tooling can be reduced, but the precision and reliability may be compromised
Solution Approach 1:
An intermediary coupling mechanism is introduced between the off-the-shelf power tools and the CNC system. This intermediary interface adapts the manual tools to work within the CNC framework, providing precise positioning, controlled actuation, and reliable data feedback, thereby maintaining reliability while utilizing cost-effective commercial tools.
