RFID-Embedded Dressing Tool for Grindstone Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dressing processes for grindstones lack a mechanism to ensure the correct selection of dressing tools corresponding to the type of grindstones, leading to potential misuse and reduced grinding performance.
Innovation Solution
A dressing tool equipped with a radio frequency identifier (RFID) tag that stores information about the tool and grindstones, allowing a grinding apparatus to recognize and verify the suitable dressing tool, and update usage information, preventing incorrect tool selection and extending tool life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual selection of dressing tools is used, then operator flexibility is maintained, but incorrect tool selection occurs leading to reduced grinding performance
Solution Approach 1:
An RFID tag is introduced as an intermediary component attached to the dressing tool. This tag stores identification information that enables automatic verification by the control unit, eliminating manual selection errors without requiring complex mechanical or optical identification systems
Solution Approach 2:
The manual mechanical selection process is replaced with an automated electromagnetic identification system using RFID technology. The control unit automatically reads the RFID tag information and verifies tool-grindstone compatibility, substituting human judgment with electronic verification
2Duration of action of moving object
If dressing tool information is not tracked, then tool management is simple, but tool life and performance cannot be monitored
Solution Approach 1:
The RFID tag serves as an information carrier that stores and transmits tool identification and usage data. This intermediary enables automatic tracking of dressing tool service life and performance metrics without requiring complex manual recording systems
Solution Approach 2:
The control unit reads RFID tag information to obtain usage data and provides feedback regarding tool life status and performance. This feedback mechanism enables automated monitoring and management of dressing tool service life without increasing operational complexity

AI summary
A dressing tool, to be used in dressing a plurality of grindstones arrayed in an annular pattern on one surface side of a grinding wheel, includes a dressing section for dressing the plurality of grindstones, a support plate that is located on a side opposite to a front surface side of the dressing section making contact with the plurality of grindstones and that supports a back surface side of the dressing section, and an RFID tag from and in which information concerning the dressing tool is read and written. One of or both the support plate and the dressing section are provided with a recess, and the RFID tag is disposed in the recess and is fixed by a non-conductive material provided in the recess.
