| Abstract Scope |
A thick sheet ironing process is normally used to control the uniform wall thickness of products. To evaluate the performance of lubricants by conventional tests, such as Ring Compression Test (RCT) is not suitable due to the limitation in the low level of normal contact pressure, surface expansion, and relative velocity. In this research, Ball Ironing Test (BIT) was proposed as a new simulative tribo-test. Finite Element Modeling (FEM) together with the statistical analysis was employed during the design and determine the frictional indicator of the BIT. According to the results, the maximum load is very sensitive to the friction and can be used as an indicator to evaluate and approximate the friction coefficient via Frictional Calibration Curve. Different types of lubricants were tested experimentally and demonstrated different performance during the BIT. In conclusion, the BIT is suitable for evaluating the ironing process. |
