Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turning tools lack a reliable method for supplying cooling or lubricating media to the tool engagement area during machining, especially when the tool attachment is radially adjusted, which can disrupt the coolant supply.
Innovation Solution
A multi-part turning tool with a bore system that delivers coolant from the base tool to the turning tool attachment via a sealed groove system, ensuring continuous coolant supply even during radial adjustments, and an adjustable outlet element aligns the coolant with the cutting edge of the indexable insert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-part turning tool with radially adjustable attachment is used to machine non-circular profiles, then adaptability and versatility are improved, but the reliability of coolant supply to the tool engagement area deteriorates due to disruption during radial adjustments
Solution Approach 1:
The tool is divided into a base tool and a separable turning tool attachment that can be radially adjusted and locked at different positions. This segmentation allows the attachment to be optimized for specific machining tasks while maintaining a reliable coolant supply system through the base tool interface.
Solution Approach 2:
A groove system acts as an intermediary coolant passage between the base tool and the turning tool attachment. The groove receives coolant from the base tool and directs it to the tool engagement area, ensuring continuous coolant supply even when the attachment is radially adjusted to different positions.
2Adaptability or versatility
If the turning tool attachment is radially displaceable on the base tool, then adaptability for various diameters is improved, but the sealed coolant delivery system deteriorates due to interface disruption
Solution Approach 1:
The turning tool attachment is designed to be radially displaceable and lockable on the base tool, allowing dynamic adjustment to different machining diameters. The groove system maintains sealed coolant delivery throughout the adjustment range by providing a continuous coolant passage that accommodates the radial movement.
Solution Approach 2:
The groove system functions as a hydraulic conduit that delivers coolant under pressure from the base tool to the tool engagement area. The groove geometry ensures that coolant flow is maintained even when the attachment is positioned at different radial distances from the tool rotation axis.
3Productivity
If coolant is supplied through the tool interface, then productivity is improved through efficient cooling, but device complexity increases due to the bore system design
Solution Approach 1:
The tool interface is designed with a central bore and cylindrical surface that can supply coolant to multiple different turning tool attachments. This universal interface design maintains efficient coolant delivery while reducing overall system complexity by using a standardized coolant supply mechanism across different tool configurations.
