Milling Cutting Tool with Axial Turning Rake Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milling/cutting tools require separate tools for turning and milling operations, and when used for turning, they often necessitate a special immobilizing apparatus to prevent rotation, which complicates the process and increases equipment needs.
Innovation Solution
A milling/cutting tool with a tool main unit rotated about an axis and a plurality of tips disposed in the circumferential direction, where turning rake surfaces face the axial direction, allowing for both milling and turning operations without a special immobilizing apparatus, by adjusting the tool and workpiece positioning relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cutting tool is used for both turning and milling operations, then tool versatility is improved, but the tool structure becomes more complex requiring multiple blades and positioning mechanisms
Solution Approach 1:
The cutting tool is designed with multiple blades having different functions (milling blades and turning bits) arranged alternately on the same tool main unit, allowing a single tool to perform both milling and turning operations by rotating to different blade positions
Solution Approach 2:
The tool main unit is divided into multiple functional segments with milling blades and turning bits disposed in an alternating manner, enabling independent selection of specific blade types for different operations while maintaining a unified tool structure
2Manufacturing precision
If a special immobilizing apparatus is used to prevent tool rotation during turning operations, then turning precision is improved, but the equipment complexity and cost increase
Solution Approach 1:
The tool main unit incorporates a self-immobilizing mechanism where the weight distribution and geometric arrangement of alternating milling blades and turning bits create automatic balancing, allowing the tool to maintain stable positioning during turning operations without external immobilizing apparatus
3Adaptability or versatility
If multiple blades are disposed with spacings in the circumferential direction, then both milling and turning capabilities are achieved, but the tool length and contact area increase
Solution Approach 1:
Instead of extending the tool length radially to accommodate multiple blades, the blades are arranged in the circumferential direction around the tool main unit, utilizing the rotational dimension to pack multiple functional elements within a compact radial footprint
