Abstract：

Some quality problems of stamping parts can be found by monitoring the close gap of mould parting surface. A method to monito dies close gap was proposed. Three eddy current displacement sensors were installed on the die. The close gap of every stamping was recorded and analyzed. When the gaps exceed certain value, a warning message will be given to the operator. The sheet forming test shows that the die gap can be measured accurately with a precision of 0.01 mm. The method can be used to monitor some kinds of sheet forming process，which could reduce the time to change or adjust of the die, improve the quality of stamping parts and save cost.
