Raw Material Shape Determination for Thin Plate Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing thin plate-shaped materials do not provide a clear method for determining the required raw material shape, making it difficult to set and process materials with predetermined shapes.
Innovation Solution
A method involving material information acquisition, flange classification, grip portion setting, and raw material shape calculation to determine the shape of the raw material, including classification of flanges as L, T, counterclockwise-T, or '+' types, and setting the grip portion accordingly to calculate the raw material shape based on acquired information and classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a raw material shape is not predetermined, then processing flexibility is maintained, but processing accuracy and efficiency deteriorate
Solution Approach 1:
The patent applies preliminary action by determining the raw material shape in advance before processing begins. The shape determination unit calculates the required raw material shape based on the target component shape and processing method, then provides this predetermined shape information to guide material preparation. This ensures the raw material is properly shaped before processing starts, improving processing accuracy without adding complex real-time control systems.
2Manufacturing precision
If a complex shape determination method is used, then processing accuracy improves, but processing time increases
Solution Approach 1:
The patent segments the shape determination process into distinct functional units: a shape determination unit that calculates the raw material shape, a flange classification unit that categorizes flange types, and a grip portion setting unit that identifies gripping locations. This segmentation allows each unit to perform its specific function efficiently using simple algorithms, reducing overall computation time while maintaining high shape determination accuracy.
Solution Approach 2:
The system applies self-service by automatically determining the raw material shape, classifying flanges, and setting grip portions without requiring manual intervention. The shape determination unit autonomously calculates the required shape based on target component geometry and processing parameters, eliminating time-consuming manual calculations and ensuring consistent accuracy.
3Measurement precision
If flange classification is performed, then grip portion setting accuracy improves, but processing complexity increases
Solution Approach 1:
The patent applies local quality by classifying flanges into specific types (L-type, T-type, + type) based on their local geometric characteristics. Each flange type has specific gripping requirements, and the grip portion setting unit uses this localized classification information to accurately determine grip positions. This local classification approach improves grip portion positioning accuracy while keeping the classification logic simple and rule-based.
