CamsCams are a type of mechanical device that is used to convert rotary motion into linear motion or vice versa. A cam is typically a disk or cylinder with a profile that is designed to produce a specific motion when it rotates. Cams are commonly used in a wide range of applications, including mechanical systems, engines, and machine tools. They are often used to operate valves, levers, or other mechanical components, and can be used to produce a wide range of motion profiles, including oscillating, reciprocating, or continuous motion. Cams are typically made of metal or other materials that are resistant to wear and fatigue, and may be used in combination with other mechanical components such as bearings, springs, or followers. Cams are an essential component of many mechanical systems, and play a crucial role in converting rotary motion into linear motion or vice versa.
