Sliding cams are mechanical devices that convert rotational motion into linear motion. They consist of a rotating disk or wheel with a specially shaped groove or cam profile. As the cam rotates, a follower moves along the groove, translating the circular motion into a straight line movement. These devices are commonly used in various applications, such as in automotive engines and industrial machinery. Sliding cams can help control the timing of movements, making them essential for tasks that require precise synchronization, like opening and closing valves or operating robotic arms.
