Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools lack an effective method for accurately determining the state of the cutting edge, leading to inefficiencies in machining processes.
Innovation Solution
A cutting tool equipped with sensors and a communication unit that transmits measurement information, including serial numbers, to a processing device outside the tool, allowing for precise determination of the cutting edge state based on machining conditions and measurement results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement information is transmitted without serial numbers, then transmission simplicity is maintained, but measurement order recognition becomes inaccurate
Solution Approach 1:
The patent applies preliminary action by assigning serial numbers to measurement information in advance, before transmission occurs. This pre-tagging approach ensures that when measurement data is transmitted from the cutting tool to the external device, the serial numbers are already attached, enabling accurate chronological reconstruction of measurement sequences without requiring complex synchronization protocols or post-processing sorting mechanisms.
2Productivity
If all measurement results are transmitted continuously, then data completeness is improved, but data extraction and analysis efficiency decreases
Solution Approach 1:
The patent applies the extraction principle by enabling selective retrieval of specific measurement data based on serial numbers. Instead of requiring processing of all transmitted measurement information, the external device can extract only the specific measurement results needed for analysis by referencing their serial numbers, significantly improving data processing efficiency and reducing the computational burden of handling large volumes of measurement data.
3Reliability
If measurement information is transmitted after cutting start timing, then relevant machining data is captured, but timing synchronization becomes complex
Solution Approach 1:
The patent applies preliminary action by establishing a clear temporal reference point (cutting start timing) and assigning serial numbers to measurement information based on this reference. This pre-defined timing framework simplifies synchronization by providing a universal reference point for both the cutting tool and external device, eliminating the need for complex continuous synchronization protocols while ensuring all measurement data is properly timed and ordered.

AI summary
A cutting tool includes: a cutting section having a cutting edge; a sensor provided in the cutting section; and a communication unit provided in the cutting section. The communication unit transmits, to a processing device provided outside the cutting tool, measurement information relating to measurement results of the sensor and including serial numbers corresponding to the measurement results after a timing of a start of cutting by the cutting edge.
