In Product-Service use phase, Customer and PSS provider share "ba", and customer perceives their values by their context which are component of "ba". Ba can be thought as a shared space for emerging relationships. Ba may also be thought of as the recognition of the self in all. According to the theory of existentialism, ba is a context which harbors meaning. Thus, ba is considered to be a shared space that serves as a foundation for knowledge creation. Product-Service should appropriately clarifies contexts and their sharing state. Based on that, it is necessary to comprehend and satisfy customer requirements. This paper proposes a modelling method which constructs relationships between ba, context and requirement. And, it enable to logically comprehend customer requirements.

There is a demand for improving the removal rate of Fluid Jet Polishing to polish hard materials used for artificial joints or rough surfaces of additive manufactured products down to ultra-precision condition. The existing method of directly adding compressed air into the slurry has a problem that machining accuracy is degraded. In this research, we proposed a new method of adding cavitation bubbles by ultrasonic into the slurry jet. Acoustic and fluid dynamics simulations confirmed that the cavitation bubbles generated in the nozzle can reach the surface of a workpiece before disappearing.

MQL, Minimum Quantity Lubrication, has been developed and applied for practical use in metal machining process mainly in the automotive industry for environmental reason. Typical work materials are carbon steel, aluminum and cast iron. Meanwhile in recent years led by the aircraft industry, the use of ceramics has been studied for high heat resistance and / or high abrasion resistance. Therefore, we measured the grinding resistance and tool wear for basic grinding technology development for the free-form shape creation on alumina ceramics with the aid of MQL technology in the study.

The purpose of this research work is pattern transfer to a diamond surface using wear. Because the surface of diamond is worn by contacting with carbon steel, the diamond is pushed onto the circumference side of rotating disk. When the diamond is processed, burr occurred at the side of disk. Therefore, the burr is removed during the processing. After processing, the shape of the disk is transferred to the surface of the diamond.

The fabrication of microarray on curved surface usually requires macro tool and micro tool, respectively. But the two different machining processes and devices lead to the processing complexity and difficulty of high-freedom microarray curved surface. Hence, the grinding of micro-cutting-edge array on macro cutting edges of ball-end cutter is proposed by using a micro V-tip of diamond wheel. The objective is to directly replicate the micro-cutting edges on cutter to the milled freeform surface. First, the geometric parameters of micro-cutting-edges on cutter were established; then geometric relationship between the micro V-tip of diamond wheel and the micro-cutting-edges on cutter was established. The results show that micro-tip angle of diamond wheel and micro-cutting-edge position have greater impact on microarray curved surface, but cutter radius, wheel radius and grinding depth have smaller impact. As a result, the microarrays may be directly machined on macro freeform surface during 5-axis milling by the micro-grinding of micro-cutting-edges on ball-end cutter.

This paper describes the machining characteristics of non-contact micro electrical discharge machining (EDM) using the controlled pulse train method (CPTM). The CPTM was introduced to increase discharge energy and enlarge unit removal per crater in micro EDM. With this, group of discharges generated within a controlled predetermined time is allowed to occur at a single location on the machined surface. By fixing a cylindrical feeding electrode coaxially to the mandrel, capacitance C1 can be formed between the feeding electrode and the tool to realize the non-contact electrical feeding. Using a newly made feeding electrode, micro holes will be drilled at different speed of tool electrode rotation. The influence of the tool rotation speed on material removal rate (MRR) and tool wear rate (TWR) will be investigated. By drilling deep holes, hole straightness and machining accuracy will be observed.

The use of thin foil EDM slicing is developing as an alternative method for the slicing of single crystal silicon carbide (SiC). Aiming to improve the machining rate and kerf width accuracy, two alternatives are proposed: reduction of the tool electrode side surface area and insulation of the tool side surface. For the former, a foil electrode with holes is proposed. With this electrode design two effects are expected: reduction of kerf width, due to the decrease of the possibility of side surface discharges, and the enhancing of machining rate, due to the improvement of flushing conditions. For the latter, insulated resin was coated on the foil electrode surface, mainly for avoiding the side surface discharges. Moreover, with the objective of enhancing flushing conditions, the effect of jump motion is also studied. The slicing process has been performed by applying a relative motion between a tensioned foil electrode and a workpiece. The results discussion has been focused on kerf width value, machining speed and electrode wear.

Micro-rods are widely used in micro discharge machining (EDM) and micro electrochemical machining (ECM) as tool electrode. Since the material of tungsten has the advantages of high stiffness and good electrical and thermal conductivity, it is usually fabricated to make tool electrodes. In this research, tungsten micro-rods were machined with the electrochemical machining method (ECM), furthermore, the neutral sodium nitrate (NaNO3) was used as the electrolyte, instead of the alkaline electrolyte used by most of other researches. Since the bipolar current was needed to machine tungsten with the neutral electrolyte, it caused the disadvantage of tool wear due to the dissolution of anode in the negative polarity of the pulse power supply. The influence of the machining conditions on the tool wear was investigated in this research.

The ECM is a non-traditional machining method. In the gap of electrochemical machining (ECM), the products in the gap, which includes bubbles, not only influence the distribution of current density, but also the current efficiency of ECM processes. It is well known that in the case of NaNO3 as electrolyte, the pulse width is shorter, the current efficiency is lower. However, the reason of this phenomenon has not been elucidated. In this research, the phenomenon was investigated directly using the transparent electrode by the high speed camera.

We developed the MEMS blood flow sensor. But blood flow varies with contact pressure applied by setting it because blood vessels are elastic. Therefore a mechanism to maintain contact pressure is necessary for an accurate measurement of blood flow. We made a device to measure blood flow and contact pressure simultaneously. To this end, we measured them of the cow and studied the appropriate contact pressure in the blood flow measurement of the cow.
