Shaping Machine Jig Position Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shaping machine systems require expert knowledge for producing shaping data and are not easily operable by non-experts, as they necessitate prior knowledge of the shaping device's characteristics and are not portable or easily installable.
Innovation Solution
A shaping machine system that includes a computer with input units for selecting jigs and shaping tools, a shape data reading unit, a shaping data producing unit, and a drive control unit, which can measure jig positions, detect position errors, and correct shaping data, allowing for operation by users without expert knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shaping data is produced according to shaping device characteristics, then manufacturing precision is improved, but ease of operation deteriorates because expert knowledge is required
Solution Approach 1:
The shaping device automatically measures its own jig positions and the computer automatically corrects shaping data based on these measurements, eliminating the need for expert operators to manually calculate corrections
Solution Approach 2:
The system implements automatic feedback loops where jig position measurements are continuously fed back to the computer, which then automatically corrects shaping data to maintain manufacturing precision without expert intervention
2Manufacturing precision
If a dedicated shaping machine system is installed in a factory, then manufacturing precision is maintained, but ease of manufacture deteriorates due to installation time and effort
Solution Approach 1:
The computer system is designed to be portable and adaptable to different locations while maintaining shaping precision through automatic jig position measurement and data correction capabilities
Solution Approach 2:
The system replaces complex mechanical installation requirements with electronic measurement and software-based correction mechanisms, allowing the shaping device to be easily relocated while maintaining precision
3Manufacturing precision
If shaping data is corrected according to jig position error, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The computer acts as an intermediary between the shaping device and the control system, handling all complex correction calculations through software while the hardware remains relatively simple
Solution Approach 2:
Complex correction mechanisms are replaced with software-based algorithms in the computer that automatically calculate and apply shaping data corrections based on measured jig position errors
