Adjustable-Angle Cutting Tool for Different Helical Flute Leads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools can only process one type of helical flute with a specific lead, requiring multiple tools for different leads, which increases component storage costs.
Innovation Solution
A cutting tool design that allows the head portion to be mounted on the holder at adjustable angles around the center axis, enabling the radial rake angle of the cutting insert to be changed, thus processing helical flutes with different leads using a single tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cutting tool uses a fixed mounting orientation for the cutting insert, then the tool structure is simple, but only one type of helical flute can be processed requiring multiple tools for different leads
Solution Approach 1:
The head portion is designed to be rotatable relative to the holder body around the center axis, allowing dynamic adjustment of the cutting insert's radial rake angle. This enables the same tool to process helical flutes with different leads by changing the mounting orientation, thereby improving versatility without requiring multiple fixed tools
Solution Approach 2:
The cutting tool is designed with a universal head portion that can be mounted at multiple angular positions on the holder. This allows a single tool to perform multiple functions by processing different types of helical flutes with varying leads, eliminating the need for multiple specialized tools
2Reliability
If multiple cutting tools are used to process different helical flute leads, then each tool is optimized for its specific function, but component storage cost increases
Solution Approach 1:
The cutting tool employs a universal holder and head portion combination that can accommodate different cutting inserts at various angular orientations. This multi-functional design allows one tool to replace multiple specialized tools, reducing the quantity of tools that need to be stored while maintaining reliable processing quality for different helical flute types
3Adaptability or versatility
If the head portion can be mounted at adjustable angles, then different radial rake angles are achievable, but the mounting mechanism becomes more complex
Solution Approach 1:
The mounting mechanism incorporates a rotatable head portion that can be adjusted to different angular positions relative to the holder body. This dynamic adjustment capability allows changing the radial rake angle of the cutting insert by rotating the head portion around the center axis, providing adaptability while keeping the mechanism relatively simple through rotational movement

AI summary
Provided is a cutting tool including: a head portion which includes an insert mounting seat on which a cutting insert is installed; a shank which is installed on the rear end side of the head portion and holds the head portion; and a bolt which fixes a position of the head portion with respect to the shank when the head portion is mounted on the shank. The head portion is configured to be mountable to the shank, with the angle thereof changing around a center axis.
