Nowadays the majority automobile companies try to develop the fuel effective and powerful car. To satisfy these needs, the total mass of vehicle has to be decreased and the torque of engine is increased. Therefore the transmission gears have to decrease their size and increase their hardness. These make several defects such as chattering, wave and swelling during the gear profile grinding process which is a kind of gear machining process to improve the noise quality of the transmission. These defects cause noise and vibration during operating the transmission. However it is difficult to find out the defects during grinding machining process because the inspection machine spends a lot of time to measure the gear profile. In this paper the monitoring system of gear profile grinding machining is developed to detect the defect in realtime.

Nowadays, manufacturing industry has been making its effort not only for productivity elevation but also for cost reduction in order to survive in the global market which is more and more challenging. In this paper, the method for planning of digital manufacturing system is proposed and door trim assembly system is determined as the subject of our research. First of all, the process sequence is generated based on the product analysis. And, the static and dynamic relationships between system components are represented using IDEF0 and UML model. The working time is estimated through the regression analysis based on MODAPTS method. According to the system configuration strategy, initial concept system layout is implemented 3D virtual environment. The problems caused by bad working motions are detected and modified through the ergonomic analysis using RULA method. According to proposed procedure, digital door trim assembly system is implemented in DLEMIA.
