Cutting Tool Multi-Port Flow Path Intersecting Coolant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools face inadequate cooling in regions other than where the coolant is directly sprayed, leading to inefficient heat dissipation during machining processes.
Innovation Solution
A cutting tool design featuring a holder with a flow path system that includes multiple outflow ports and flow paths, where the coolant is sprayed from these ports in a manner that intersects above the cutting insert, ensuring efficient cooling of the insert and reducing coolant scatter to non-cooled regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple nozzles are positioned above the cutting insert for localized cooling, then specific regions are cooled effectively, but overall cooling coverage becomes inadequate
Solution Approach 1:
The cooling system transitions from a single-point or single-line cooling approach to a multi-dimensional cooling pattern by positioning outflow ports at different locations and orientations. The first and second flow paths deliver coolant to different spatial zones, creating a three-dimensional cooling coverage that expands the total cooled area while maintaining effectiveness at each target zone.
2Temperature
If coolant is sprayed in a concentrated manner to achieve local cooling, then cooling intensity at the spray point increases, but coolant scatter to non-cooled regions occurs
Solution Approach 1:
The coolant flow is segmented into separate streams through the first and second flow paths, each delivering cooling to specific designated areas. This segmentation prevents the coolant from scattering uncontrollably across non-cooled regions, as each flow path is configured to direct coolant only to its intended target zone with controlled dispersion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances cooling efficiency over a wider area of the cutting insert, stabilizes coolant flow, and prevents coolant scatter, thereby improving machining performance by maintaining tool integrity and reducing chip welding.
Implementation Method 1
The holder includes a flow path including an inflow port and an outflow port... The first flow path includes, as the outflow port, a first opening located at a side of the first end and located above the insert. The second flow path includes, as the outflow port, a second opening located at a side of the first end and located above the first opening.
Implementation Method 2
A cooling fluid (coolant) is sprayed from the first nozzle toward an upper side surface of the cutting insert. The cooling fluid is also sprayed from the second nozzle toward a higher level position than the cutting insert.
Implementation Method 3
a region where the cooling fluid is sprayed from the first nozzle and the second nozzle is locally cooled down
