Numerical Controller Sound Converting Unit for Machine Tool Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing numerical controllers for machine tools primarily rely on visual information for evaluating and adjusting drive axis motion, making it difficult for operators to intuitively recognize and adjust parameters, especially when auditory information like oscillation and resonation sounds are involved, and requiring operators to be physically present near the machine.
Innovation Solution
A numerical controller with a sound converting unit that converts time-series data of drive axis physical quantities into audible sound, allowing operators to select and synthesize waveforms for intuitive parameter adjustment, even remotely, by generating sound conversion data that can be output as sound, and simulating the effects of parameter changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual information is used for evaluating drive axis motion, then the operator can analyze data displayed on a monitor, but the operator cannot intuitively recognize auditory information such as oscillation sound or resonation sound
Solution Approach 1:
The patent introduces a sound converting unit as an intermediary that transforms visual waveform data into auditory sound signals. This mediator enables the operator to perceive machine sounds and oscillations through hearing, complementing the existing visual display and providing intuitive auditory feedback for parameter adjustment without requiring physical proximity to the machine.
Solution Approach 2:
The patent replaces the need for physical presence near the machine (mechanical proximity requirement) with an electronic signal processing system. By converting waveform data into sound signals through digital processing and outputting them via speakers or headphones, the system substitutes the mechanical requirement of being physically close to hear machine sounds with an electronic information transmission pathway.
2Loss of information
If the operator stays in the vicinity of the mechanical device to hear the sound, then the operator can recognize machine sound, but the operator cannot perform remote evaluation and adjustment
Solution Approach 1:
The patent replaces the mechanical requirement of physical proximity with an electronic signal processing system. By converting waveform data into sound signals through digital processing and outputting them via speakers or headphones, the system substitutes the mechanical requirement of being physically close to hear machine sounds with an electronic information transmission pathway, enabling remote operation.
Solution Approach 2:
The patent creates a virtual copy of the machine's acoustic environment by generating sound signals from measured waveform data. Instead of requiring the operator to be physically present to hear actual machine sounds, the system synthesizes and outputs representative sound signals that replicate the machine's acoustic characteristics, allowing remote auditory evaluation.
3Measurement precision
If frequency analysis is performed to recognize the effect of filter adjustment, then the operator can evaluate the adjustment effect, but the operator cannot intuitively understand the adjustment effect
Solution Approach 1:
The sound converting unit acts as an intermediary that translates precise frequency analysis data into intuitive auditory signals. While frequency analysis provides accurate measurement of adjustment effects, the converted sound signals provide intuitive understanding, allowing the operator to immediately perceive the impact of filter adjustments through changes in sound characteristics without requiring complex data interpretation.
