.... In this study, HTCs are investigated experimentally by using a servo-drive press. With the flexibility that the servo-drive press offers, effect of various blank holder pressures on temperature change is determined. Before and after surface roughness conditions of aluminum and magnesium (from two different...

... research and development activities in the area of plastic forming of metals and will be a valuable resource for our colleagues and friends. A paper on “Using Servo-Drive Presses to Determine the Effect of Blank Holder Pressure on Temperature Change in Warm Forming of Sheet” is presented by Altan’s...

... to their limited formability at room temperature, forming needs to take place at elevated temperatures and mostly under nonisothermal conditions. In this study, nonisothermal deep drawing process using aluminum and magnesium alloys was investigated using a servo motor driven press and a heated tool set. Using...

...Jionghua Jin; Jianjun Shi A transfer or progressive die process consists of multiple stations working simultaneously in each stroke. This paper aims to develop a new methodology that can decompose press tonnage signals to obtain individual station signals without using in-die sensors. In the paper...

...W. Z. Guo; K. He; K. Yeung; R. Du This paper is the second part of our study on designing a new type of metal forming press. In the first part of the study ( Du, R., and Guo, W. Z., 2003, ASME J. Mech. Des., 125(3), pp. 582–592 ), a new controllable mechanical press is introduced that consists...

...Jionghua Jin, Assistant Professor In multiple operation stamping processes, a press tonnage signal measured by press tonnage sensors installed on press linkages/uprights, is the summation of die forces at all stations. Different from the current practice of using a whole cycle of press tonnage...
