Machining technology using ultrasonic systems (sound pressure measurement analysis, oscillation control).

The Ultrasonic System Research Institute has developed "ultrasonic oscillation control (processing) technology" that utilizes the acoustic characteristics (vibration response characteristics and nonlinear phenomena) of objects (tools, target items, etc.) through a sound pressure measurement analysis device (ultrasonic tester) and a megahertz ultrasonic oscillation control probe. With this developed technology, it has become possible to control nonlinear vibration phenomena in target objects through "ultrasonic oscillation and output control," achieving dynamic control of ultrasonic waves (changes in bispectrum). The original ultrasonic oscillation control probe allows for the utilization and control of nonlinear effects of ultrasonic vibrations. This is an effective ultrasonic utilization (control) technology tailored to applications such as processing, cleaning, surface modification, and promoting chemical reactions. There are interactions with the acoustic characteristics of cutting tools (drills, reamers, cutters, knives, etc.) and the size and material of cutting oils, jigs, and target objects, making the analysis (self-correlation, impulse response, contribution rate, bispectrum) complex. However, various optimizations based on the analysis results of sound pressure measurement data become possible.

To stabilize the effects of ultrasound, a statistical perspective is essential.

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" using a <statistical approach> concerning the utilization of ultrasound. <About the Statistical Approach> Statistical mathematics has both abstract and concrete aspects, and through contact with concrete entities, abstract thoughts or methods are developed. This is the characteristic of statistical mathematics. - From "Statistics in Science" edited by Hirotsugu Akaike <About Models> Models are constructed with the aim of effectively advancing understanding, prediction, and control regarding the subject. Building an accurate model is difficult, and the examination is always conducted in a form that appropriately "rounds off" the complexity of the subject. In this sense, the process of constructing or building a model requires statistical thinking. <About the Relationship Between Models and Current Systems> (Points to Consider When Reflecting) 1) It is necessary to consider that preconceived notions and experiences may not be correct. 2) To think about the essence of a model, I believe it is effective to utilize category theory.
