Milling Tool Insert with Angular Offset for Dual Setting Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milling tools can only operate with a single setting angle, limiting their versatility and requiring modifications to change angles, which is inefficient and inconvenient.
Innovation Solution
Incorporating second cutting inserts with an angular offset between the base and cutting edge sections, allowing for the same inserts to be clamped in the same position but with a different setting angle, enabling easy switching between angles without modifying the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a milling tool is designed with a single type of cutting insert, then the tool structure remains simple, but the tool can only operate with one setting angle, reducing versatility
Solution Approach 1:
The cutting insert is designed with two different setting angles (first setting angle and second setting angle) on the same insert body. The insert can be installed in two different orientations on the insert seat, allowing the milling tool to perform machining operations with either setting angle using the same physical insert and insert seat, thus achieving multi-functionality without requiring multiple specialized inserts or modifying the tool structure
Solution Approach 2:
The cutting insert incorporates a dynamic configuration where the cutting edge can be positioned at different angles relative to the base section. By rotating or reorienting the same insert on the insert seat, the active cutting edge presents different setting angles to the workpiece, enabling the tool to adapt to different machining requirements without physical modification of the tool itself
2Adaptability or versatility
If different cutting inserts with different setting angles are used, then versatility is improved, but the complexity of managing and replacing inserts increases
Solution Approach 1:
A single cutting insert design incorporates both the first setting angle and the second setting angle, eliminating the need to maintain inventories of different insert types for different angles. The same insert can be used in both orientations, simplifying insert management and replacement operations while maintaining versatility
Solution Approach 2:
Instead of using different inserts for different setting angles, the invention inverts the approach by making one insert serve multiple angle configurations. The insert is designed so that its cutting edge can present different angles to the workpiece through different installation orientations, reversing the conventional wisdom that one insert type equals one setting angle
3Adaptability or versatility
If the milling tool is modified to accommodate different setting angles, then versatility is improved, but the device complexity and modification requirements increase
Solution Approach 1:
The insert seat is designed with a universal geometry that can accommodate the cutting insert in two different orientations. No modification to the insert seat or tool body is required; the same insert seat structure supports both the first setting angle and second setting angle configurations, maintaining ease of manufacture while achieving versatility
Solution Approach 2:
The cutting insert is segmented into distinct functional sections: a base section and a cutting edge section with an angular offset between them. This segmentation allows the insert to be manufactured with built-in angular geometry that provides both setting angles, eliminating the need to modify the tool structure itself while achieving multi-angle capability

AI summary
The milling tool comprises a carrier body (12) having a rotational axis (14). The carrier body is arranged distributive over its circumference, and has multiple insert seats (15) for retaining and mounting of cutting plates (16a), which have a base section with a contact surface. The base section is pressed by clamping units towards a counter contact surface (20) at the insert seat, and is firmly clamped in a defined installation position.
