Reconstruction of high-speed cam curve based on high-order differential interpolation and shape adjustment

作者：

Highlights：

• A high-order differential interpolation curve is first constructed by using basis functions on each node.

• An adjustable cam curve is then reconstructed by adding variable shape factors on critical nodes.

• A high-speed cam curve with high fidelity, high-order continuity and low peak jerk is developed.
