What is reciprocating?

Reciprocating motion is a repetitive back-and-forth linear motion. It is found in a wide range of mechanisms, including engines (like internal combustion engines where pistons reciprocate), pumps (e.g., reciprocating pumps), saws (reciprocating saws), and compressors. The motion is often achieved via a crank or cam mechanism, which converts rotary motion into reciprocating motion or vice versa. The technology is essential in many mechanical systems for generating force, pumping fluids, and cutting materials.
