Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face challenges in documenting and evaluating the effectiveness of measures taken to mitigate chatter vibrations in machine tools, making it difficult to efficiently converge subsequent vibrations.
Innovation Solution
A display control device that associates and displays information on the machining program block or line being executed with changes made to the tool's rotating speed or feed rate, allowing operators to track and analyze the effectiveness of their adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operators manually record operations to track effectiveness of chatter vibration measures, then information completeness is improved, but time consumption and operational complexity increase
Solution Approach 1:
The system automatically records and manages operation information without requiring manual intervention from operators. The display control device autonomously captures machining program block information, change instructions, and vibration convergence data, eliminating the need for operators to manually document their actions while maintaining complete information records.
Solution Approach 2:
The system provides automated feedback by displaying whether vibration convergence was achieved after each change instruction, and by recording the relationship between machining program blocks and applied changes. This feedback mechanism enables operators to efficiently evaluate the effectiveness of their measures without manual recording time.
2Measurement precision
If operators manually document changes to rotating speed or feed rate, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The display control device automatically captures and records the precise values of rotating speed and feed rate changes along with the corresponding machining program block information. This self-service recording eliminates manual documentation requirements while maintaining precise measurement of all parameter changes.
Solution Approach 2:
The display control device acts as an intermediary that automatically records and displays the relationship between change instructions and their outcomes. It mediates between the operator's actions and the system's responses, providing precise measurement data without requiring manual intervention from the operator.
3Reliability
If detailed operation records are maintained, then reliability of vibration convergence is improved, but device complexity increases
Solution Approach 1:
The display control device autonomously maintains detailed operation records including machining program block information, change instructions, and vibration convergence outcomes. This self-service record-keeping improves reliability by ensuring consistent and complete documentation without adding operational complexity for the user.
Solution Approach 2:
The system merges the recording function with the existing display control device, combining multiple functions (information recording, display control, and convergence tracking) into a single integrated system. This merging approach improves reliability through comprehensive record-keeping while avoiding the need for separate complex documentation systems.
Data Source
AI summary
A display control device according to an embodiment includes a display control unit. In the display control device, when an instruction to change a rotating speed or a feed rate of a tool is received during execution of a machining program, information on a block or line of the machining program being executed when the change instruction is received and a change corresponding to the change instruction are associated with each other. Upon receiving selection of a change instruction, the display control unit displays (a) information on either of the block or a line of the machining program and (b) the change on a screen.
