Study on the relation between servo press motion and friction using miniature friction sensors and friction control forming

本研究的目的是利用微型摩擦传感器测量工件与刀具表面之间的摩擦，阐明伺服压力机运动与摩擦之间的关系，并将结果应用于摩擦控制成形。为此，设计并制造了一种微型摩擦传感器。用于热锻压的传感器的耐热性、耐热应变片和粘接都受到了挑战。进行了锻压试验，研究了凸模角周围的变形情况。制造了一种插入摩擦传感器的冲床，以检测冲床角周围的摩擦。

The purpose of this study is to elucidate the relation between servo press motion and friction by the measurement of friction between the work and the tool surface using a miniature friction sensor and to apply the results to friction control forming. For this purpose, a miniature friction sensor has been designed and manufactured. For the heat proof of the sensor for the application to the hot forging, heat proof strain gauge and bonding has been challenged. Forging test has been carried out to investigate the deformation around the punch corner. A punch to insert the friction sensors has been manufactured to detect the friction around the punch corner.
