According to the ubiquitous times that is new important topic, the miniature is demanded in the industry at large. The high accuracy and accumulation make the assembly equipment and the production equipment huge from the size of view. The huge equipment brings about the expensive price of the equipment, a low flexibleness and a low productivity. It makes the manufacturing equipment huge that the accuracy only depends on the mechanism stiffness. The position of two assembled parts is transformed with the global coordinate system whose datum is machine coordinate system. The purpose of this research is invention of the module that can adjust one part to the order part automatically. The module that has a function of self adjustment only takes a stiffness in assemble direction and can be moved freely in the other direction so this function makes a self adjustment. The self adjustment module reduces the tact time and also diminishes the inferior goods and makes reconfigurable machine in $\mu-part$ assembly.

4S-Van is being developed in order to provide the spatial data rapidly and accurately. 4S-Van technique is a system for spatial data construction that is heart of 4S technique. Architecture of 4S-Van system consists of hardware integration part and post-processing part. Hardware part has GPS, INS, color CCD, camera, B/W CCD camera, infrared rays camera, and laser. Software part has GPS/INS integration algorithm, coordinate conversion, lens correction, camera orientation correction, and three dimension position production. In this paper, we suggest that adequate 4S-Van design is needed according to application environment from various test results.

The objective of this study is to investigate endurance test of localization part for T-50 aircraft engine. Major localization parts of the engine (F404-STW-102) was performed using Accelerated Simulated Mission Engine Test. The purpose of this test is to evaluate of quality demonstration capability, to verify design of engine localization parts, and to improvement safety and operation rate of T-50 advanced trainer by finding out operational problems in production phase and fixing it.

In this study, we designed and constructed a multi-forming progressive die with a bending, embossing on the multi-stage and performed through the try out. Out of the characteristics of this paper that nothing might be ever seen before such as this type of research method on the all of processes of thin and high precision production part.

This is the continue paper as part 2 in this study. In order to prevent the production defects, the optimum design of product, jig and fixture and their making are very significant devision. especially the result of tryout and its analysis become the characteristics of this paper that nothing might be ever seen before such as this type of research method on all processes.

The purpose of this study is developing scheduling logic and program for machining scheduling of automobile part production line with unbalanced processing time. Three rules are developed to minimize slack and effect on other job. Fourth rule is suggested which considered weighted sum of three factors. schedule is generated totally 1, 000 times and then optimal weight parameter is selected. The program is developed to schedule situation to compare with the performance measure, total finish time of machine and total tardiness of part. As a result, the rule which considered weighted sum of three factors is effective for both measure.

In Factory Automation environments such as FMS, the formation of machine-part based on GT should be considered. The purpose of this study is to develop a economic heuristic algorithm which considers various elements such as unit processing time, subcontract cost, and functional operation cost, machine processing capacity etc. When this proposed approach is applied to the real situation expected benefits are as follows: the reduction of production lead time work in process, labor force, tooling, rework and scrap, setup time, order time delivery, and paper work, etc.

A computer method is developed for group technology layout and its simulation analysis. The method is composed of three phases: Phase I sorts the parts by its similar production routes and forms part families. Phase II plots the layout by machine cell and evaluates the group layout alternatives by the total process time analysis and the part travel distance evaluation analysis. Phase III also evaluates the alternatives by simulation analysis using SIMAN simulation software. All the computer programs are developed with BASIC except SIMAN simulation.
