What type of cam is specifically designed to achieve high speeds?

A rotary cam is specifically designed to achieve high speeds due to its continuous circular motion, which allows for rapid rotation and smooth operation. The design of a rotary cam allows it to maintain a consistent speed while transferring motion from the cam to the follower, which is essential in applications that require quick and efficient movement. This type of cam is often used in machinery where rapid cycling and precision are necessary, such as in automated production lines or high-speed machinery.

In contrast, flat cams typically operate at lower speeds and are primarily used for applications requiring linear motion. Conical cams are more suited for applications where the angular position of the follower needs to change gradually rather than at high speeds. Cylindrical cams, while versatile, are also not optimized for high-speed applications when compared to rotary cams, making the latter the ideal choice for scenarios demanding high-speed performance.
