Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for thermal displacement correction in machine tools are challenging due to the difficulty in visually determining precise adjustment amounts, which are minute, and require expensive actual machine tools for training, posing economic and operational risks.
Innovation Solution
A thermal displacement correction training unit on a computer simulates a virtual machine tool with precision decline imitation and calculation units, allowing operators to practice thermal displacement correction and adjustment without using actual machine tools, featuring a virtual machine tool unit, control unit, and display unit that imitates and displays precision decline and correction amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actual machine tools are used for training operators on thermal displacement correction, then training effectiveness is improved, but economic cost increases and operational disruption occurs
Solution Approach 1:
The patent creates a virtual copy of the machine tool system that replicates thermal displacement behavior and correction operations. This virtual model allows operators to practice adjustment procedures without requiring actual machine tools, thereby eliminating the economic cost and operational disruption while maintaining training effectiveness through realistic simulation of the correction process
2Reliability
If actual machine tools are used for training operators on thermal displacement correction, then training effectiveness is improved, but operational disruption occurs
Solution Approach 1:
By creating a virtual replica of the machine tool system, the patent enables training operations to occur independently of actual production equipment. Operators can practice thermal displacement correction procedures in the virtual environment without temporarily stopping production on real machines, thus maintaining operational continuity while achieving training objectives
3Ease of operation
If visual adjustment method is used for thermal displacement correction, then ease of operation is improved, but measurement precision deteriorates due to minute adjustment amounts
Solution Approach 1:
The patent employs visual display techniques where the virtual machine tool interface shows color-coded or magnified representations of thermal displacement and correction amounts. This allows operators to visually perceive minute adjustment quantities that would otherwise be imperceptible, maintaining ease of visual adjustment while improving measurement precision through enhanced display feedback
Solution Approach 2:
The patent transforms minute linear displacement measurements into visually perceivable graphical representations on the display screen. By converting microscopic correction amounts into scaled visual indicators within the virtual interface, operators can accurately judge adjustment precision through visual feedback without being limited by the actual minute dimensions of the physical adjustments
