Multi-Outlet Coolant Nozzle for Cutting Insert Chip Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools often require separate liquid dispensing systems or multiple nozzles with single outlets, which can be inefficient in fluid delivery and may not effectively manage debris and temperature during metalworking operations.
Innovation Solution
A cutting tool with a single nozzle having multiple integrated fluid outlets, where the nozzle can have various passageways extending through it, providing fluid outlets with different cross-sectional shapes and sizes, is designed to enhance fluid flow and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate liquid dispensing system or multiple nozzles with single outlets are used, then the cutting tool can deliver fluid to the workpiece, but the fluid delivery efficiency and velocity are insufficient
Solution Approach 1:
The nozzle is segmented into multiple passageways (first, second, and third passageways) that branch from a single inlet, creating multiple outlets in different directions. This segmentation allows fluid to be distributed to multiple locations simultaneously, improving fluid delivery efficiency and coverage without requiring multiple separate nozzles or a complex dispensing system.
Solution Approach 2:
Multiple fluid delivery functions are merged into a single integrated nozzle component. The nozzle combines multiple passageways with different orientations and outlet positions into one unit, replacing what would traditionally require multiple separate nozzles or a complex dispensing system. This merging improves efficiency while simplifying the overall system.
2Speed
If multiple nozzles with single outlets are used, then fluid can be directed to different areas, but the velocity and coolant delivery performance are limited
Solution Approach 1:
The nozzle internal flow path is segmented into multiple passageways (first passageway extending in first direction, second passageway extending in second direction, third passageway extending in third direction) that diverge from a common inlet. This segmentation creates multiple flow paths that can optimize velocity in different directions simultaneously, improving overall coolant delivery performance without requiring multiple separate nozzle components.
Solution Approach 2:
The nozzle design transitions from a single-direction flow to multi-dimensional flow by creating passageways that extend in different directions (first, second, and third directions). This dimensional expansion allows fluid to be delivered to multiple areas with optimized velocity in each direction, achieving better coolant delivery performance without increasing the number of separate nozzle components.
3Productivity
If a single nozzle with multiple integrated outlets is used, then fluid delivery efficiency and velocity improve, but the nozzle design becomes more complex
Solution Approach 1:
The nozzle internal structure is segmented into distinct passageways (first, second, and third passageways) with different orientations and outlet positions. Each passageway is designed to deliver fluid in a specific direction, allowing optimized coolant delivery to multiple areas. The segmentation is achieved within a single integrated nozzle body, improving productivity while managing complexity through functional organization.
Solution Approach 2:
The single nozzle component performs multiple fluid delivery functions simultaneously through its multiple passageways. The nozzle is designed to deliver coolant in different directions and to different locations at the same time, making it a multi-functional component that replaces what would traditionally require multiple separate nozzles. This multi-functionality improves coolant delivery performance while consolidating the system into a single component.

AI summary
A cutting tool includes a main body having a working end and an attachment end. A seat is disposed in the working end to receive a cutting insert. A main body passageway for the communication of fluid is disposed in the main body and has a passageway end disposed in the working end. A cutting insert is disposed in the seat. A nozzle is disposed in the passageway end. The nozzle has a nozzle body including front and rear surfaces. The front surface faces generally toward the seat, and the rear surface faces generally away from the seat. The nozzle body defines a plurality of nozzle passageways that extend therethrough between the front and rear surfaces. Each nozzle passageway has a fluid outlet at the front surface.
