Abstract：

The friction in the process of metal forming is a very intricate dynamic process.It has a great effect on quality of forming.Measuring the dynamic process is very difficult,but the dynamic process must be measured and studied.The process of dynamic friction under different lubrication conditions in punch bulging wes studied with acoustic emission technology.The result indicates that different states of lubrication produce different signals of acoustic emission and different signals of acoustic emission corresponding with different states of lubrication.It is feasible that the lubrication state can be measured and inspected with acoustic emission signal.
