Laser Machining Route Display for Multi-Factor Defect Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining route display devices for laser machining primarily rely on display color and shade changes to indicate laser output issues, failing to account for other factors that may cause defects in the workpiece, such as laser output magnitude, reflected light, and gap variations between the machining head and workpiece.
Innovation Solution
A machining route display device that acquires positional information, laser machining data, and machine configuration data to calculate and display the machining route, with adjustable display formats for laser output, reflected light, and gap data, allowing for intuitive recognition of relationships between the machining route and various data sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display color and shade are changed only according to laser output values, then it is possible to identify laser output issues, but other factors causing machining defects cannot be detected
Solution Approach 1:
The patent segments the machining route display into multiple independent data layers, each representing different machining parameters (laser output, reflected light, gap distance). Each layer can be independently configured with its own color mapping, allowing comprehensive defect detection while maintaining clear visual organization of multiple factors
Solution Approach 2:
The display device is designed to handle multiple types of machining data universally through a single integrated system. The same display infrastructure supports various data types (laser output, reflected light intensity, gap measurements) with configurable color schemes, making the system adaptable to different defect analysis needs
2Adaptability or versatility
If multiple types of machining data are displayed with different color formats, then comprehensive defect analysis is enabled, but display complexity increases
Solution Approach 1:
The patent applies local quality by allowing different color mapping strategies for different data types within the same display. Each data layer (laser output, reflected light, gap) can have its own customized color scheme and shade variations, enabling comprehensive data representation while maintaining intuitive local interpretation for each parameter type
Solution Approach 2:
The display system dynamically adjusts color formats based on the selected data type and machining conditions. The color mapping is not fixed but can be configured and changed according to different analysis needs, allowing the display to adapt to various defect scenarios without requiring multiple separate display systems
3Measurement precision
If detailed machining data is displayed for every control cycle, then precise defect location is achieved, but information processing load increases
Solution Approach 1:
The patent uses the machining route geometry as a visual copy or template onto which machining data is mapped. Instead of displaying raw data tables, the system projects data values onto the visual path representation, allowing precise defect location through spatial visualization while reducing processing overhead compared to tabular data display

AI summary
A machining route display device includes a display section for displaying a machining route based on coordinate values of a laser machining head calculated by a laser machining head coordinate calculator and display formats set by a first display format setting section and a second display format setting section. At least one of a display color of first data and a shade of the display color of the first data is changed in accordance with the first data acquired by a first data acquiring section, and at least one of a display color of second data and a shade the display color of the second data is changed in accordance with second data acquired by a second data acquiring section.
