Blade Holder IC Tag Management for Cutting Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting blades with embedded wireless IC tags are prone to breakage during manufacturing and usage, especially due to vibrations and shocks, making them impractical in terms of manufacturing cost and effectiveness for managing the use history of cutting blades in cutting apparatuses.
Innovation Solution
A cutting apparatus with a chuck table, detachable cutting blade, control means for processing conditions, and a blade case holder with an IC tag for reading and writing use history information, where the read/write means is connected to the control unit to reflect and update the use history information of the cutting blade, ensuring easy and suitable management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wireless IC tag is embedded in the cutting blade for storing use history information, then the use history management capability is improved, but the reliability of the cutting blade deteriorates due to breakage during manufacturing and usage
Solution Approach 1:
The system separates the IC tag from the cutting blade itself. The cutting blade and the information storage device (blade case with IC tag) become independent components. The blade case holder includes a reading/writing device that communicates with the IC tag in the blade case, allowing use history management without embedding fragile electronics in the blade.
Solution Approach 2:
The blade case holder serves as an intermediary between the cutting blade and the IC tag. When the blade is mounted on the cutting apparatus, the blade case holder positions the blade case (containing the IC tag) near the reading/writing device, enabling automatic information exchange without direct integration of the IC tag into the blade structure.
2Ease of manufacture
If an IC tag is provided on the blade case for storing use history information, then the ease of manufacture is improved, but the device complexity increases due to additional reading and writing components
Solution Approach 1:
The blade case holder serves multiple functions: it holds the blade case containing the IC tag, positions the blade case for automatic reading/writing operations, and integrates the reading/writing device into a single component. This multi-functionality reduces overall system complexity despite adding information management capabilities.
Solution Approach 2:
The system implements automatic reading and writing of use history information between the cutting apparatus and the IC tag in the blade case. This self-service mechanism eliminates manual information entry and reduces operational complexity, as the system automatically manages data exchange when the blade is mounted or removed.

AI summary
A cutting apparatus including a cutting unit on which a cutting blade is detachably mounted, a control unit for controlling the cutting unit, and a blade case holder for holding a blade case for storing the cutting blade is provided. The blade case is provided with an IC tag allowing reading and writing of use history information of the cutting blade. The control unit is connected to a read/write unit for reading the use history information from the IC tag of the blade case held by the blade case holder and writing the use history information to the IC tag. The use history information read from the IC tag by the read/write unit is reflected in processing conditions for a workpiece to be processed, and the use history information after processing of the workpiece is written to the IC tag by the read/write unit.
