The 20th International Conference on Precision Engineering (ICPE2024), Nov. 2024, [Reviewed] - Practical Method for Identifying Model Parameters for Machining Error Simulation in End Milling Through Sensor-Less Monitoring and On-Machine Measurement
Kazuki Kaneko; Arisa Kudo; Takanori Waizumi; Jun Shimizu; Libo Zhou; Hirotaka Ojima; Teppei Onuki, Depending on cutting conditions, unacceptable machining errors are caused by tool deflection in end milling operations. Many studies have proposed methods for predicting the machining error owing to the tool deflection to achieve the theoretical optimization of the cutting conditions. However, the conventional machining error simulation is not practically utilized to determine the optimal cutting conditions. Tool system stiffness parameters and cutting coefficients must be identified in advance to simulate machining errors. However, dynamometers and displacement sensors are required for parameter identification. Therefore, it is impossible to identify the required parameters in typical factories, which do not possess such special equipment. In this study, a practical method was developed to identify the stiffness parameters that can be determined in factories. The proposed method employs on-machine measurement and sensor-less cutting force monitoring to achieve practical parameter identification. In the proposed method, the profile milling is first conducted. During the milling operation, the cutting force and cutting torque are monitored through a controller based on the sensor-less monitoring technique. After the operation, the machining error distribution on the machined surface is measured on machine using a touch probe. The required parameters are identified by minimizing the differences between the measured and theoretical forces, torques, and machining error distributions., Fuji Technology Press Ltd.

小貫 哲平; 日下 祐太郎; 周 立波; 又平 浩; 中山 健一; 小野塚 英明; 松井 淳; 尾嶌 裕隆; 清水 淳,The method of acquisition, analyzation and evaluation of cutting characteristics was developed on a hollow rectangular tube-like structure made of an electrical insulating paper (so called the slot liner in the motors of electric vehicles). The slot liner was cut by a steel disk blade. The cutting force was measured by the dynamometer, to evaluate the specific energy of the cutting: Cp, and the ratio of tangential and normal component of the force: μ, as the indicators of the cutting quality. Parameter estimations were applied using computer simulations of the slot liner in evaluating Cp and μ, with different cutting history (cutting length) of the blades. The difference of the cutting quality was found in variation of μ. Then filling up the hollows using the solid type jig and observations of by high-speed camera were helpful for eliminating the effect of the deformation.

トライボロジスト, Dec. 2016, [Reviewed] - Development of separation method for industrial waste by using acoustic standing wave field
Tomohiro INADA; Libo ZHOU; Hirotaka OJIMA; Jun SHIMIZU,In recent years, more than 10 million tons of industrial wastes are discarded annually. Those wastes are mainly composed of plastic, glass and metals which are the materials massively used in automobiles, electric and electronic products. It is well known that industrial waste contain precious metals like gold and have a great value of reutilization. Therefore, technology to properly separate the waste by their types of subject is very important for recycling industry. In this study, we have developed a new separation method by use of acoustic levitation phenomenon in a standing wave field. Unlike the conventional methods such as centrifugal particle separation or magnetic separation, this method enables to sort subjects by their densities, without relying on other material properties including size, magnetism and weight. First described in this paper is a theoretical analysis of levitation force exerted on an object to derive its trajectory in a standing wave field. It is found that the motion of the object is governed by its density and the strength of acoustic field. Based on this finding, we developed a prototype of separation system with twin-transducers and a belt conveyer. As a result of test to separate a mixture of SiO2 and Fe particles, 62wt% SiO2 is captured at node side while 72wt% Fe is captured at anti-node side. Finally, the prototype is used to repeatedly separate the chipped waste of actual OA equipment. Its density was increased about 150%.

Hirotaka OJIMA; Takuya NAGAYAMA; Libo ZHOU; Jun SHIMIZU and Teppei ONUKI, The shape and distribution of abrasive grains in the grinding wheel have a significant influence on the grinding performance. Therefore in order to realize the high-precision grinding process, it is essential to measure the shape and distribution of abrasives on wheel working surface. We have developed an on-machine 3D measurement system to study the surface topography of grinding wheel by binocular stereopsis without demounting the wheel from the grinding machine. In comparison to the results measured by the laser microscope, the developed system has been confirmed to have the accuracy of -5.6% in the horizontal direction and -3.4% in the vertical direction. Also, we analyzed the behavior and variation of individual grains by tracking observation of 3D topography of the grinding wheel working surface in the grinding process by using this system. As the result, the distribution and variation of abrasive grains including protrusion height, flat part length, half-tip angle, grain density and effective cutting edge density are able to be quantitatively evaluated., 精密工学会

Key Engineering Materials, 2012, [Reviewed] - Study on Surface Profile Evaluation for Large Si Wafer Measurement -1st Report : Denoising by Use of Wavelet Transform-
Libo ZHOU; Masashi ONO; Hirotaka OJIMA; Jun SHIMIZU, In recent semiconductor industry, production and evaluation of ever flatter, thinner and larger Si wafer are required to fulfill the demands in high integration and cost reduction. However, uncertainty in measurement of wafer profile is encountered as a severe problem because the resolution required for analysis of wafer flatness is reaching the limits of available instrument. Thus, the measured profile data always incorporate a certain degree of noise and this noise component behaves to bias the outputs of wafer profile such as SFQR (Site Frontsite least-sQuares focal plane site Range), GBIR (Global Backside Ideal Range), bow, warp and etc.. In order to precisely evaluate the wafer geometry, it is essential to remove the noise from the measured data. Described in this paper is design and development of digital filters for denoising by use of wavelet transform. Compared to the conventional low-pass filters, the developed filter not only provides better performance of decomposition in the spatial frequency domain, but also offers the new capability of filtering in amplitude components., The Japan Society for Precision Engineering

Kenji Nagase; Hirotaka Ojima; Yoshikazu Hayakawa, This study considers realization of the wave control for the uniformly varying damped mass-spring systems controlled by the active mass dampers (AMD). We first derive a necessary and sufficient condition for the exact impedance matching to ensure the internal stability. Since the condition is very restrictive and we also need to prevent the drift of the AMD in practice, we next consider the relaxed impedance matching condition and propose a control design method to realize the relaxed impedance matching and to prevent the drift of the AMD. As a design example of the proposed method, the wave control for the multi-story structure is also presented. Efficiency of the controller is examined numerically and experimentally., The Society of Instrument and Control Engineers

Hirotaka Ojima; Kenji Nagase; Yoshikazu Hayakawa, This paper concerns with active vibration control of non-uniform damped mass-spring systems by the wave control. Especially, this study considers clarifying a class of a damped mass-spring system that can be analyzed by the wave-based analysis. Because the wave properties are determined by the propagation constants, three conditions for the propagation constants are considered. Necessary and sufficient condition for the physical parameters to hold the three conditions is obtained. Moreover, for this class of damped mass-spring systems, properties of the propagation constants and the characteristic impedances, which achieve the impedance matching, are studied. Numerical examples are shown to prove efficiency of the impedance matching controller., The Society of Instrument and Control Engineers
