Dual-Tool Docking Machine for Fast Large-Part Contour Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining devices are inefficient when processing large workpieces with fine contours, as they require powerful drives for large tools, leading to low travel speeds and long processing times due to the need for re-clamping or prolonged processing.
Innovation Solution
A device with a linear drive arrangement that allows the tool holder to be moved relative to the tool carrier, enabling the use of smaller, lighter tools for fine machining, with high-speed and acceleration capabilities, and an interface for quick tool changes between tool carrier and linear drive arrangement to accommodate both large and small tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large tools with powerful drives are used for machining large workpieces, then high cutting performance is achieved, but traverse speeds of tool holders decrease due to higher mass and force absorption requirements
Solution Approach 1:
The device is segmented into two independent tool holder systems: a first tool holder for large cutting tools and a second tool holder for small precision tools. Each tool holder has its own drive arrangement optimized for its specific function, allowing independent operation without compromising the performance of either system.
Solution Approach 2:
The device combines multiple functions in a single machining center: both rough machining of large workpieces and fine machining of detailed contours can be performed without repositioning. The control unit coordinates both tool holders to provide universal machining capabilities for diverse workpiece requirements.
2Productivity
If devices are designed for large tools with high cutting performance, then material removal capability is improved, but machining time for fine contours becomes disproportionately long
Solution Approach 1:
The device dynamically switches between two tool holder configurations based on the machining requirements. The control unit enables rapid switching between the first tool holder for rough machining and the second tool holder for fine machining, optimizing the machining process in real-time without manual intervention.
Solution Approach 2:
The first tool holder performs rough machining operations in advance to remove bulk material, preparing the workpiece for subsequent fine machining by the second tool holder. This preliminary action reduces the overall machining time by pre-processing the workpiece to the appropriate state for detailed work.
3Adaptability or versatility
If workpieces with diverse requirements are processed in different fixtures, then each workpiece type receives optimal machining, but time is spent reclamping workpieces
Solution Approach 1:
A single machining center incorporates both a first tool holder for large workpieces and a second tool holder for small workpieces with fine contours. The control unit coordinates both tool holders to provide universal machining capabilities, eliminating the need for multiple specialized fixtures and reducing setup time between different workpiece types.
