Machining technology utilizing megahertz ultrasonic vibrations.

The Ultrasonic System Research Institute has developed a technology for ultrasonic <dynamic control> that optimizes the interaction of ultrasonic vibrations based on various analysis results of ultrasonic propagation states using an original ultrasonic system (sound pressure measurement analysis and oscillation control) and an abstract algebra model. Note: The control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to existing control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) related to the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we offer it as consulting services (there is an increasing track record of precision cleaning and stirring at the nano level). Note: Dynamic changes in the propagation state of tanks, transducers, target objects, and tools are measured, analyzed, and evaluated using original technology (ultrasonic testers).

The Ultrasonic System Research Institute conducts consulting related to the use of ultrasound by applying feedback analysis technology based on multivariate autoregressive models, utilizing a technique for measuring, analyzing, and evaluating the propagation state of ultrasound. By organizing the measurements, analyses, and results obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the appropriate state of ultrasound for specific purposes. Note: Nonlinear characteristics (dynamic characteristics of acoustic flow), response characteristics, fluctuation characteristics, effects due to interactions, etc. By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various detailed effects related to vibrational phenomena, referencing statistical mathematical concepts. As a result, there is an increasing number of cases demonstrating the effectiveness of new nonlinear parameters related to the propagation state of ultrasound and the surface of the target object, such as changes in bispectrum and changes in autocorrelation. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on good confirmations.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound using two function generators. This technology enables the control of ultrasonic nonlinear phenomena and resonance phenomena through different types of (sweep) oscillations using two different waveforms. By applying this technology, we are developing practical methods to alleviate residual stress on component surfaces and various application technologies, and we provide consulting services. Example 1: 1) Sweep oscillation control from 1.0 MHz to 15 MHz 2) Sweep oscillation control from 0.6 MHz to 5 MHz 3) Precision cleaning at the nano level using a 42 kHz 35W ultrasonic cleaner Example 2: 1) Sweep oscillation control from 3 MHz to 20 MHz 2) Sweep oscillation control from 60 kHz to 3 MHz 3) Nano dispersion treatment of metal powders using a 42 kHz 35W ultrasonic cleaner Standard Settings: 1) Sweep oscillation control from 3 MHz to 20 MHz 2) Sweep oscillation control from 60 kHz to 13 MHz 3) Dynamic control of ultrasound using a 42 kHz 35W ultrasonic cleaner
