| Abstract Scope |
Effect of production rate on the lubrication performance of environmentally friendly lubricant was investigated using the tribological test of Forward Can – Backward Can Extrusion. In this test, the lubrication performance is examined from both finite element analysis and experiment. For the lubricant, double-layer-type lubricant was used. The calibration diagram on the relationship between the extruded geometry and the punch stroke was prepared at the forming rate of 20 spm (strokes per minute) and 1 spm using FE analysis. As workpiece materials, annealed steel SCM420 and aluminum alloy A4032 with three different surface treatment conditions was used. As a result, the friction coefficient value estimated was higher when the production rate was smaller. The dependency of the friction coefficient on the production rate was able to be reasonably evaluated by the present method. |
