Abstract
Traditionally, the input speed of a Stevenson-type press is constant. Here, we propose a novel approach by varying the input speed of the crank to make the ram’s motion suitable for both deep-drawing and precision-cutting. This approach uses a servomotor as the power input. By properly designing the input speed, the output motion can pass through a desired trajectory. The input motion characteristics are planned with Bezier curves. Optimization is used to improve the output characteristics. Guidelines for defining the optimization problems are discussed. Additional dimensional synthesis is also suggested for reducing the input speed variation. Design examples are given for illustration.
