Abstract
Abstract Servo press has the ability to improve the formability, quality, and productivity of metal products by working with various forming curves of slide. However, the operations of free-motion function are not very intuitional and efficient for most of servo press so that it is difficult for the operator to construct self-design forming curves. Furthermore, most studies in the field of servo press only focus on the simulation of the drawing process, and rarely have experiment to support its result. While this study discuss the drawing motion design by the proposed program on the aspect of process efficiency and energy. In this proposed forming curves design program, operators determine the motion of slide by adjusting several control points of forming curve in a user-friendly and graphical interface. Then a calculating process based on the B-spline and curve fitting theories is applied in the program to transform settings of operator into position, speed, acceleration, and jerk information, which plays a vital role for the operator to design forming curves. Moreover, this study focus on the planning and designing the drawing motion, and discuss the mechanism of generating the drawing motion curve. The result of this study is, by applying the proposed program design for servo press, operators are able to create practical and satisfying forming curves more easily. Moreover, the drawing motions design by the proposed program are more efficient and energy saving.
