Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In panel cutting operations, small parts tend to be displaced due to reduced vacuum force, leading to incorrect cuts and compromised subsequent cutting performance, which is economically and production-process-wise onerous.
Innovation Solution
A method for determining the starting point of a cutting path for each piece to maximize holding during cutting, involving steps like selecting the central point of a side, defining material surrounding ranges, and calculating the maximum distance based on the cutting tool's diameter, to ensure precise positioning and sequencing of cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high-speed rotating end mill is used to cut panel pieces, then cutting speed and productivity are improved, but the stress on small pieces causes them to displace from their position
Solution Approach 1:
The method determines the optimal starting point for cutting before the actual cutting operation begins. By calculating and selecting a starting point that maximizes the area of surrounding material, the piece is kept firmly attached to the panel during the initial stages of cutting, preventing displacement caused by the stress of high-speed cutting.
Solution Approach 2:
The invention changes the parameter of cutting sequence by determining a specific starting point based on the area of surrounding material. This parameter optimization ensures that cutting begins from a location that provides maximum structural support, allowing high-speed cutting to proceed without causing piece displacement.
2Productivity
If the cutting tool stresses the piece during high-speed rotation, then cutting efficiency is improved, but the piece may displace leading to incorrect cuts
Solution Approach 1:
Before high-speed cutting begins, the method preliminarily determines the optimal starting point by calculating the area of surrounding material for each potential starting location. This preliminary analysis ensures that cutting starts from a position that maximizes piece stability, preventing displacement and ensuring cutting accuracy throughout the high-speed operation.
Solution Approach 2:
The method incorporates a feedback mechanism by evaluating the area of surrounding material and using this information to determine the optimal starting point. This feedback ensures that the cutting process begins from a location that provides maximum structural support, maintaining both cutting efficiency and accuracy.
3Productivity
If small pieces are cut from the panel, then panel yield is improved, but the vacuum holding force on these small pieces is reduced
Solution Approach 1:
The method preliminarily determines the optimal starting point for cutting small pieces by calculating the area of surrounding material. By selecting a starting point that maximizes this area, the piece remains firmly attached to the panel during cutting, compensating for the reduced vacuum holding force on small pieces and preventing displacement.
Solution Approach 2:
The invention changes the cutting parameter by optimizing the starting point selection based on the area of surrounding material. This parameter optimization ensures that even small pieces with reduced vacuum holding force are cut from a position that provides maximum structural support, maintaining both panel yield and cutting accuracy.
