What is the function of a feed screw in a machine?

The feed screw plays a crucial role in machining by controlling the linear movement of either the tool or the workpiece along a designated axis. This precise movement is essential for achieving accurate cuts and desired shapes during the machining process. The feed screw can convert rotational motion into linear motion, allowing for adjustments in feed rate and positioning. By allowing the operator to set specific distances and speeds, the feed screw ensures consistent machining and helps in producing parts with tight tolerances.

Other options, while related to machining, do not capture the primary function of a feed screw. For instance, regulating temperature, holding workpieces, or supplying coolant are important aspects of machining operations but are managed by different components rather than the feed screw itself.
