This paper presents a methodology for the simulation and optimization in a virtual environment of a manual assembly process. For validation of the methodology the authors chose an assembly process that is already used in the manufacturing industry. In the first step of the proposed methodology the existing process is simulated and then based on the simulation the activities and equipment involved are being analyzed and in the next step the assembly process is to be optimized using simulation and a series of modification vectors such as: layout, devices, tools and movement sequences. The case study presented in the paper aims to optimize the assembly process of a pneumatic actuator of a butterfly type valve.

It is a common design practice to balance all rotating members of a machine. Rotating parts can be designed to be inherently balanced by their geometry. However, due to production tolerances there will be some small unbalance in each part. Therefore a balancing operation may be required for each part after manufacture. In the case of electrical motors the major source of vibration and noise is unbalance in the armature. In the motor manufacturing industry, this problem is generally corrected by removing material from the armature. However, the number of unbalance armatures is generally high and therefore the balance operation is usually a bottleneck in the production line. As a result, the manufacturing process becomes inefficient and costly. Based on the fact that a motor manufacturing company is facing balancing problems in its production line, this paper presents a dynamic balancing analysis of the armature in an automobile starting motor. A theoretical balancing analysis is carried out using the design and manufacture information. Balancing is also experimentally studied at the assembly line by measuring the unbalance through the whole manufacturing process. Both analysis, theoretical and experimental, and then compared. From this comparison several external factors that affect the unbalance in the real assembly process are identified. As a result, design changes and production process modifications are proposed to reduce the armature unbalance.
