Cutting Tool Coolant Port Layout for Shifting Cutting Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools face complications in ensuring that a coolant effectively hits the cutting edge when the position of the edge is changed, leading to a complex structure if a mechanism for adjusting the ejection port direction is provided.
Innovation Solution
The cutting tool is designed with an ejecting portion that ejects fluid toward an elongated region including the cutting edge, allowing the fluid to consistently hit the edge even when the position changes, without requiring a separate mechanism to adjust the ejection port direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanism for adjusting the direction of the ejection port is provided to ensure the fluid hits the cutting edge when the position changes, then the reliability of coolant delivery is improved, but the device complexity increases
Solution Approach 1:
The ejection port is designed with an elongated shape extending in a predetermined direction, changing the geometric parameters of the port to create an extended ejection region. This allows the fluid to be ejected toward a region rather than a specific point, maintaining reliable coolant delivery to the cutting edge regardless of its position changes, without requiring any adjusting mechanism
Solution Approach 2:
The ejection port is divided into multiple segments (multiple ejection ports may be formed aligned in a predetermined aligning direction), each contributing to the overall elongated ejection region. This segmentation approach creates comprehensive coverage along the cutting edge's possible position range while keeping each individual port simple in structure
2Temperature
If the ejection port is designed to eject fluid toward a specific point (cutting edge), then the cooling effect is maximized, but the adaptability to position changes is reduced
Solution Approach 1:
The ejection port extends in a predetermined direction (aligning direction) to create an elongated ejection region, transitioning from a point-based ejection to a region-based ejection. This dimensional extension allows the fluid to effectively reach the cutting edge across multiple positions along the aligning direction, simultaneously achieving effective cooling and adaptability to position changes

AI summary
A cutting tool with a simple configuration is provided which can cause a fluid to reliably hit a cutting edge. The cutting tool includes a holder, a cutting insert having a cutting edge and mounted on the holder, and an ejecting portion which ejects a fluid from several ejection ports toward the cutting edge. The ejection ports eject the fluid toward a region including the cutting edge and extending in a predetermined direction.
