Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for processing panel-shaped workpieces, such as those made of wood or wood-based materials, face inaccuracies and reduced machining quality due to the constant scanning force not accounting for varying workpiece resilience, which differs based on material and shape, leading to inconsistencies in processing.
Innovation Solution
A device equipped with a property detection system that assesses the workpiece's resilience by applying a predetermined force and measuring deformation, allowing for adaptive adjustment of the scanning force and infeed positioning to match the workpiece's properties, ensuring precise and accurate machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a constant scanning force is applied to the workpiece, then the scanning device can be simply designed and operated, but the machining precision deteriorates due to varying workpiece resilience
Solution Approach 1:
The scanning force is made dynamically adjustable based on the detected resilience of the workpiece. The control unit modifies the scanning force in real-time according to the workpiece properties, transforming the static constant force system into a dynamic adaptive system that maintains machining precision across different workpiece types.
Solution Approach 2:
The scanning force parameter is changed adaptively based on the detected workpiece resilience. The system detects resilience characteristics and adjusts the scanning force parameter accordingly, allowing the same scanning device to optimally process workpieces with different materials and geometries without sacrificing precision.
2Measurement precision
If the scanning force is increased to improve positioning accuracy, then the relative positioning of tool and workpiece improves, but the workpiece may deform especially in batch size 1 production with varying geometries
Solution Approach 1:
The system uses feedback from the detected workpiece resilience to adjust the scanning force. The detection device measures workpiece properties, and this information is fed back to the control unit which then optimizes the scanning force to achieve accurate positioning without exceeding the workpiece's deformation threshold, particularly important for unique geometries in batch size 1 production.
Solution Approach 2:
The scanning force is adapted locally to match the specific resilience characteristics of each workpiece. Instead of using a uniform high force that could deform sensitive workpieces, the system tailors the force application to the local properties of each workpiece, ensuring accurate positioning while maintaining workpiece integrity.
3Manufacturing precision
If a property detection device is added to detect workpiece resilience, then machining accuracy improves through adaptive scanning force, but the device complexity increases
Solution Approach 1:
The detection device and control system are designed to handle multiple workpiece types and properties through a single integrated system. The property detection device can identify various resilience characteristics, and the control unit processes this information to adjust scanning parameters, making the system universally applicable to different workpiece geometries and materials without requiring multiple specialized devices.
