Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools with cooling ducts are limited by manufacturing constraints, making it complex to produce curved ducts and inefficient to achieve precise cooling and lubrication at the process zone, especially since traditional methods restrict the orientation and course of cooling ducts.
Innovation Solution
The use of generative manufacturing methods, such as 3D printing, allows for the design of cutting tools with cooling ducts and outlet cross-sections that can be optimized for precise coolant delivery, enabling efficient and targeted cooling and lubrication by creating elongate outlet sections that can be precisely directed at the cutting edge.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional drilling or milling methods are used to produce cooling ducts, then manufacturing simplicity is maintained, but the orientation and course of cooling ducts are limited and cannot be precisely directed at the process zone
Solution Approach 1:
The patent replaces conventional mechanical drilling and milling methods with a generative manufacturing method (3D printing/additive manufacturing). This substitution enables the creation of complex curved cooling ducts with precise orientations that cannot be achieved through traditional subtractive manufacturing, directly resolving the contradiction between manufacturing precision and device complexity.
Solution Approach 2:
The invention changes the manufacturing approach from subtractive (drilling/milling) to additive (generative manufacturing), fundamentally altering the production parameters and capabilities. This parameter change allows for arbitrary duct geometries and orientations without increasing manufacturing complexity, as the additive process inherently handles complex shapes more efficiently.
2Reliability
If conventional drilling methods are used, then manufacturing cost is low, but curved cooling ducts must be approximated by straight bore sections resulting in inefficient cooling
Solution Approach 1:
The patent replaces mechanical drilling with generative manufacturing to create smooth, continuous curved cooling ducts instead of approximated straight sections. This substitution dramatically improves cooling efficiency by enabling optimal duct routing that directly targets the process zone, while the additive manufacturing process maintains ease of manufacture for complex geometries.
Solution Approach 2:
The invention utilizes curved and angled cooling ducts with optimal radii that can be precisely manufactured through generative manufacturing. The curved duct design allows coolant to flow more efficiently toward the process zone, improving cooling reliability compared to straight bore approximations, while the additive process makes these curved geometries easy to manufacture.
3Manufacturing precision
If cooling ducts are designed with optimized outlet cross-sections, then targeted cooling of the process zone is improved, but manufacturing complexity increases due to complex geometries
Solution Approach 1:
The patent replaces conventional machining methods with generative manufacturing to produce cooling ducts with complex outlet cross-sections. The additive manufacturing process can directly create these optimized geometries without the tool access limitations of traditional machining, achieving high coolant delivery precision while keeping manufacturing complexity manageable through digital modeling and direct fabrication.
4Reliability
If generative manufacturing methods are used to create complex cooling duct geometries, then cooling precision and efficiency are improved, but manufacturing cost and process complexity increase
Solution Approach 1:
The patent employs generative manufacturing as a universal process that can create the entire tool main body including complex cooling ducts, outlet cross-sections, and structural features in a single integrated manufacturing step. This multi-functionality improves cooling and lubrication efficiency through optimized geometries while managing manufacturing complexity by consolidating multiple operations into one additive process.
Solution Approach 2:
The invention changes the manufacturing paradigm from subtractive to additive, fundamentally altering how complex geometries are produced. This parameter change enables high cooling efficiency through precise duct design while the mature additive manufacturing technologies keep the manufacturing process relatively simple and cost-effective for high-value tools.
