Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing cutting tools with coolant cavities are complex, costly, and often require support structures, which can lead to unwanted residue and limit the production of complex geometries and materials, especially for coolant cavities with triangular cross sections.
Innovation Solution
A method using generative production techniques, such as additive manufacturing, to produce cutting tools with coolant cavities having essentially triangular cross sections without support structures, allowing for overhanging walls with angles greater than the overhang limit, enabling efficient and cost-effective production of cutting tools with improved machining properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional machining production methods are used to produce coolant cavities, then manufacturing precision can be achieved, but device complexity and production cost increase significantly, especially for triangular cross-section geometries
Solution Approach 1:
The patent replaces traditional mechanical machining methods with a generative production method (additive manufacturing). This substitution eliminates the need for complex machining operations, tooling, and support structures required for creating triangular coolant cavities, while maintaining manufacturing precision through controlled material deposition or fusion processes.
Solution Approach 2:
The patent changes the production method parameter from subtractive machining to additive generative production. This fundamental parameter change enables the direct creation of complex triangular geometries without the constraints of traditional machining, reducing device complexity while preserving or improving manufacturing precision through digital control of the generative process.
2Adaptability or versatility
If support structures are used in generative production of coolant cavities, then complex geometries can be produced, but production time increases and residue removal becomes necessary
Solution Approach 1:
The patent extracts and eliminates the support structure element from the generative production process. By designing the triangular coolant cavity geometry to be self-supporting during production or by using support structures that are easily removable or dissolveable, the patent removes the time-consuming steps of support structure installation and removal, while still enabling complex geometry production.
Solution Approach 2:
The patent applies preliminary action by pre-planning the geometry design to minimize or eliminate support structure requirements. The triangular cross-section design is specifically configured to allow self-support during generative production, or support structures are pre-designed to be easily removable, thereby reducing post-production cleanup time and avoiding residue issues.
3Productivity
If generative production methods are used to produce cutting tools, then productivity and cost-effectiveness improve, but manufacturing precision for complex geometries may be compromised
Solution Approach 1:
The patent replaces traditional precision machining with controlled generative production processes. Modern additive manufacturing technologies used in the patent achieve manufacturing precision comparable to or exceeding traditional machining through digital control, while simultaneously improving productivity by eliminating complex setup, tooling, and multi-step machining operations.
Solution Approach 2:
The patent changes the production approach from subtractive to additive, fundamentally altering how precision is achieved. Instead of removing material with tight tolerances, the generative method builds material layer-by-layer or particle-by-particle with precise digital control, maintaining manufacturing precision while dramatically improving productivity and cost-effectiveness for complex coolant cavity geometries.
