Which component of a lathe is responsible for supporting the cutting tool?

The carriage of a lathe is the component responsible for supporting the cutting tool. It is designed to move along the bed of the lathe, allowing the cutting tool to be positioned accurately and to travel across the workpiece during machining operations.

The carriage typically includes the tool post, where the cutting tool is mounted securely, and it can be adjusted to set the depth of cut and the angle of the tool. Additionally, the carriage is essential for longitudinal and crossfeed movements, which are crucial for performing various turning operations on the material being machined.

In contrast, the tailstock is primarily used to support the opposite end of the workpiece and can also hold a tool for drilling operations. The headstock contains the spindle and motor that drive the workpiece, and the bed provides the foundational support for all components of the lathe, allowing for stable operation. While all of these parts play significant roles in the lathe's functionality, the carriage specifically supports and positions the cutting tool for effective machining.
