Solution Overview

Problem

Existing milling tools, such as deep milling cutters and surface millers, are limited in their functionality as they cannot perform both deep milling and surface milling due to differences in their structure and cutting direction, leading to inefficiencies and unsuitable chip removal.

Innovation Solution

A ring-shaped tool with cutting teeth featuring a right-hand twist on both sides, allowing for both deep milling and surface milling capabilities by enabling radial material discharge and smooth operation in both rotation directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a deep milling ring is used for surface-parallel processing, then surface milling capability is improved, but cutting effectiveness in the desired milling direction deteriorates

Engineering Contradiction:

Improvesurface milling capabilityVSAvoidcutting effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The milling ring is designed with cutting teeth on both the radial outer edge (head region) and the side faces (end region), enabling it to perform both deep milling and surface milling functions with a single tool, thereby achieving multi-functionality and eliminating the need for tool changes

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a surface milling ring is used for non-surface-parallel processing, then deep milling capability is improved, but chip removal direction becomes unsuitable

Engineering Contradiction:

Improvedeep milling capabilityVSAvoidchip removal direction

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The milling ring incorporates dual tooth arrangements: outer toothing on the radial outer edge for deep milling with proper chip evacuation, and side toothing on the side faces for surface milling, allowing the single tool to adapt to different processing requirements while maintaining appropriate chip removal for each mode

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If different milling rings are used for deep milling and surface milling, then processing precision is improved, but device complexity increases

Engineering Contradiction:

Improveprocessing precisionVSAvoidtool variety

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention integrates both deep milling and surface milling capabilities into a single milling ring by providing cutting teeth on the radial outer edge and side faces, eliminating the need for multiple specialized tools and simplifying the tooling system while maintaining processing precision

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of separate deep milling rings and surface milling rings into one unified tool by merging the outer toothing and side toothing arrangements in a single ring structure, reducing tool inventory and complexity

Inventive Principle:

Principle #5Merging (Combining)
