    To do support that considers the worker in the cell production system, we have studied the moving tray system. This tray system mainly supports carrying parts of productions, tools, and so on, but additionally the table that enables the support of parts and tools while keeping an arbitrary inclination is hoped for. In this report, to achieve this working support table we construct Parallel Mechanism using Planar Linear Motor with high precision and rigidity, and we show the plan approaching to solve the kinematic analysis, to measure its accuracy, and to calibrate this mechanism with 3D CMM.

    We have proposed ″attentive workbench (AWB),″ an assembly cell that supports the production activities of human workers. Attentive Workbench is composed of an augmented desk interface and self–moving trays with the Sawyer planar motors. In this paper, 2nd generation prototype of AWB is realized. Practical assembly support by self–moving trays are carried out for the evaluation of the present system.

    In this study, we aim for realization of a robotic system that hands over a necessary object to a user who is working at a desk. When the user wants to use the object, the system should carry the object as soon as possible. In this paper, we introduce a self–moving tray, which is driven by a Sawyer–type 2–DOF stepping motor, as a robot. Using a self–moving tray as a robot, we will be able to realize a safe and high–speed deskwork support system. The reaching movements for moving tray and the handing–over between human and a self–moving tray are discussed here.

    The objective of this research is to support the design of human interface in mechatoronics products. In designing the human interface, feeling of mechanism behavior is important.This research proposes a new technique for evaluating the behavior of the mechanism of the human interface in the design phase by using force feedback.This paper reports a measurement experiment for behavior by using force feedback.

    This research aims to investigate operational efficiency and accuracy in the case that a human operator is displayed change of force by frequency of vibration exerted on its fingers, in a manual machine operation which needs minute force adjustment. In the previous report, it was described that the efficiency and accuracy are dependent on the method of force–to–frequency conversion. In the present report, the effect of the method on display performance is discussed from recognition ratio to stepwise change in the vibration frequency.

  • Influence of bubbles generated by discharge on EDM gap phenomena

    The dielectric liquid around the arc column in EDM gap is evaporated, decomposed and ionized, forming a bubble due to the high temperature of the arc column. Thus the gap during machining is immediately filled with the bubbles because the volume of the bubble caused by one pulse discharge is not negligibly small compared with the entire gap space. Hence it is considered that the gap conditions during consecutive pulse discharges are not similar to the conditions of the gap filled with either pure liquid or gas, but those of two–phase fluid. Hence in this study, the distribution of debris size and surface roughness obtained by consecutive pulse discharges were compared with those obtained in the mono–phase fluid.

    This paper describes simulation of machining accuracy of 5–axis dry electrical discharge machining (dry EDM). The CAM software for 5–axis dry EDM was also developed based on a CAD software. Error of the processed shape from the target shape increased when the pitch used in finishing was larger than 60% of the tool electrode diameter due to the edge wear of the tool electrode. Hence, the machining accuracy was improved by optimizing the pitch of the tool path and the compensation of the tool electrode wear using the simulation developed.

    This paper investigates the machining properties of the electrical discharge machining (EDM) at gas–liquid interface which is a new style of EDM process. The feature of the new process is that the dielectric fluid is gradually changed from EDM oil to its dissociated gas during the process and the process is continued after the gap space is filled with the dissociated gas. The influence of the machining conditions such as discharge current and discharge duration on roughness and temperature of the workpiece surface is investigated. Material removal rate and electrode wear rate are also measured. It is found from the experiments that the new process is effective for reducing surface roughness of the workpiece when temperature of the discharging surface of the workpiece is sufficiently risen. It is also found that the material removal rate is nearly zero after the gap space is filled with the dissociated gas.
