5-Axis Tool Path Display with Axis Deviation Waveforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tool control systems struggle to intuitively display the correspondence between the motion of drive axes and the tool tip in a 5-axis machine tool, making it difficult to identify defective areas on machined surfaces.
Innovation Solution
A tool path display apparatus that acquires and stores time-series data from drive axes, calculates three-dimensional tool tip coordinates, and displays this information as a time-series waveform, allowing for selection and attribute changes of specific path segments to highlight deviations and correlations with torque commands and position data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If time-series data of drive axes is displayed separately without integration, then data completeness is maintained, but intuitive understanding of tool tip position correspondence is lost
Solution Approach 1:
The patent combines multiple separate time-series data displays (drive axis positions, tool tip coordinates, torque commands) into a single integrated display screen. This merging allows operators to view all relevant information simultaneously with shared time-axis scrolling, enabling intuitive understanding of correlations between axis motions and tool tip position while maintaining complete data representation.
Solution Approach 2:
The display screen serves multiple functions simultaneously: showing drive axis positions, tool tip three-dimensional coordinates, torque commands, and enabling time-axis scrolling. This multi-functional design eliminates the need for separate displays for each data type while preserving all information and enhancing operational efficiency.
2Reliability
If all drive axis data is displayed simultaneously, then comprehensive monitoring is achieved, but identification of specific defective areas becomes difficult
Solution Approach 1:
The patent enables operators to select specific time periods or tool path portions in the display, which then highlights corresponding segments across all data representations. This local focus feature allows comprehensive monitoring of all axes while easily identifying specific defective areas by concentrating display attention on relevant time or position segments.
Solution Approach 2:
The display provides immediate visual feedback when operators select specific time periods or tool path portions, automatically highlighting corresponding data segments across all displayed parameters. This feedback mechanism facilitates rapid identification of defective areas by showing correlations between axis deviations and tool path anomalies.
3Measurement precision
If detailed time-series data is displayed, then measurement precision is improved, but visual clarity and ease of grasping correlations deteriorates
Solution Approach 1:
The display divides the screen into multiple organized regions, each showing specific data types (drive axis positions, tool tip coordinates, torque commands) with distinct visual characteristics. This segmentation presents detailed time-series data in an organized manner that maintains measurement precision while avoiding visual clutter and complexity.

AI summary
First and second screens are set for a tool path display apparatus for displaying a path of the tip of a tool attached to a machine tool. The first screen displays the three-dimensional path of the tip of the tool obtained by synthesizing the position information of the drive axes of a 5-axis machine tool. The second screen displays the waveforms of the position deviations and current instructions of the drive axes in chronological order. When a part (line segment) of the three-dimensional path of the tip of the tool is selected on the first screen, the display attribute of the corresponding time area is changed on the second screen so that the time area can be identified.
