Dressing Board Groove Code for Blade Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dressing boards for cutting blades may have their bar codes removed during the dressing process, leading to incorrect identification of the dressing board type and reduced dressable area, resulting in poor performance and economy.
Innovation Solution
A dressing board with a bar code on the front side and a groove code on the edge, where the groove code pattern corresponds to the bar code, ensuring that even if the bar code is cut off, the type information can still be identified using the groove code, and the dressable area is maintained or increased.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a bar code is formed on the front side of the dressing board for identification, then the kind information can be identified, but the bar code may be removed by cutting during dressing, leading to loss of information
Solution Approach 1:
The identification system is segmented into two independent parts: a bar code and a groove code. The groove code is formed by cutting grooves at the edge portion of the dressing board, creating a separate identification mechanism that is spatially distinct from the bar code. This segmentation ensures that if one identification method is damaged, the other remains intact and functional.
Solution Approach 2:
The groove code serves as a physical copy or alternative representation of the bar code information. The pattern of grooves corresponds to the bar code pattern, creating a redundant identification system. This copying approach ensures that the identification information is preserved even if the original bar code is damaged during the dressing process.
2Area of stationary object
If the bar code is formed on the front side of the dressing board, then identification is enabled, but the dressable area is reduced due to the bar code occupying space
Solution Approach 1:
The identification system transitions from a two-dimensional bar code to a three-dimensional groove structure. The grooves are formed at the edge portion of the dressing board, utilizing the vertical dimension and edge space rather than occupying the flat front surface area. This dimensional change allows the identification function to be achieved without reducing the dressable area on the front side.
Solution Approach 2:
The identification function is segmented from the main dressable area. The groove code is located at the edge portion, physically separating the identification elements from the dressing surface. This segmentation ensures that the bar code or groove code does not occupy valuable dressable area while still providing reliable identification.
3Area of stationary object
If the bar code is cut off during dressing, then the dressable area is effectively increased, but the identification of dressing board type cannot be ensured
Solution Approach 1:
A backup identification system (groove code) is prepared in advance at the edge portion of the dressing board. This cushioning measure ensures that if the primary bar code is damaged during cutting, the groove code remains intact and can be used for identification. The groove code acts as a protective backup that prevents information loss under adverse conditions.
Solution Approach 2:
The groove code is created as a physical copy of the identification information that is resistant to cutting damage. Unlike the bar code which is on the front surface and vulnerable to being cut off, the groove code is formed by cutting grooves into the edge portion, making it structurally more robust and less susceptible to being completely removed during the dressing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures accurate identification of the dressing board type and maintains a large dressable area, preventing erroneous selection and reducing costs by using the cutting blade to form the groove code, thus enhancing the cutting blade's performance and economy.
Implementation Method 1
The dressing is performed by cutting the dressing board with the cutting blade, so that the cutting blade is worn to some extent

AI summary
Disclosed herein is a dressing board for dressing a cutting blade. The dressing board is held on a chuck table in dressing the cutting blade. The dressing board includes a bar code formed on the front side of the dressing board for indicating kind information on the dressing board, and a groove code formed on the front side of the dressing board at an edge portion thereof, the groove code being composed of grooves having pattern corresponding to that of the bar code. Even when the bar code is cut off by the cutting blade in dressing the cutting blade, the kind information on the dressing board is indicated by the groove code left on the front side of the dressing board.
