Machine Tool Control for Automatic Polygon Surface Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an effective method for accurately detecting the position of a processing surface on a workpiece after polygon processing, necessitating preparatory planning to align the tool with the workpiece center, which is inefficient and time-consuming.
Innovation Solution
A control device and system that includes a processing data acquisition unit and a position detection unit to automatically detect the position of the processing surface based on changes in processing data such as load torque, sound, vibration, or heat, allowing for precise positioning without manual alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual preparatory planning is performed to align the blade edge position with the workpiece center position, then positioning accuracy for additional processing is improved, but the operation time and complexity increase
Solution Approach 1:
The system automatically detects the processing surface position using sensors that measure processing data (vibration, sound, load) during polygon processing. The control device autonomously calculates the processing surface center position based on detected corner positions, eliminating the need for manual preparatory alignment operations by the user.
Solution Approach 2:
The patent replaces manual mechanical alignment operations with an automated detection and calculation system. Sensors detect processing parameters, and the control device computationally determines the processing surface position, substituting the mechanical/manual alignment process with an automated measurement and calculation system.
2Ease of operation
If the blade edge position is unknown, then manual alignment operations are required, but this increases operational complexity and time consumption
Solution Approach 1:
The system performs self-positioning by automatically detecting corner positions during polygon processing and calculating the processing surface center. This eliminates the need for users to manually align the blade edge position, making the operation simpler and faster.
Solution Approach 2:
The system performs position detection and calculation during the polygon processing itself, before additional processing begins. The processing surface position is determined in advance through automated detection, eliminating the need for separate manual alignment operations.
3Productivity
If automated position detection is implemented, then preparatory planning time is eliminated, but the device complexity increases
Solution Approach 1:
The patent replaces simple mechanical alignment operations with an automated detection system using sensors and computational processing. While this increases device complexity, it eliminates manual preparatory time and improves overall productivity by enabling automatic position determination.
Solution Approach 2:
The system uses sensors to detect processing data (vibration, sound, load) during polygon processing and feeds this information back to the control device. The control device processes this feedback to automatically determine corner positions and calculate the processing surface center, enabling closed-loop automated positioning.
