Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to detect external forces and load torque, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (first sensor for radial force, second sensor for axial force, third sensor for tangential force, and fourth sensor for load torque) into an integrated detection system mounted on the tool holder. This merging approach enables comprehensive tool state monitoring through a unified system, improving measurement precision while managing device complexity through systematic integration.
2Reliability
If real-time monitoring of tool conditions is implemented, then reliability is improved, but loss of time increases
Solution Approach 1:
The management device pre-establishes reference ranges for normal tool operation based on historical data and tool specifications. By having these reference values ready before actual machining, the system can perform rapid real-time comparisons without requiring complex analysis during operation, thus improving reliability while minimizing time loss.
Solution Approach 2:
The system implements continuous feedback by comparing real-time sensor readings against pre-established reference ranges. This feedback mechanism enables immediate detection of tool abnormalities and provides real-time information to operators, enhancing reliability while maintaining efficient processing through automated comparison algorithms.

AI summary
A state detection system for a milling tool used includes: a milling tool including a shaft portion having a first end portion and a second end portion, the milling tool being rotatable about a rotation axis; a plurality of sensors attached to the shaft portion to detect an external force acting on the milling tool; a display device; and a management device. The plurality of sensors detect a first force acting on the milling tool in a first direction along the rotation axis, a second force acting on the milling tool in a direction along a plane normal to the rotation axis, and a load torque acting on the milling tool in a direction for preventing rotation of the milling tool. The management device causes the display device to display first information based on at least two of the first force, the second force, and the load torque.
