What is the primary purpose of a vise in machining?

The primary purpose of a vise in machining is to grip and hold a workpiece in place. A vise secures the workpiece firmly during various machining processes such as drilling, milling, or grinding, ensuring stability and precision. This stability allows machine operators to perform tasks accurately and safely, minimizing the risk of movement that could lead to defects or accidents. The design of a vise, which includes two parallel jaws that can be opened and closed, enables it to accommodate various shapes and sizes of workpieces, providing versatility in the machining process.

While measuring cutting speed, supporting tool changes, and applying lubrication are important aspects of machining, they do not directly relate to the specific function of a vise. Hence, these roles are performed by different tools or systems in the machining setup rather than by the vise itself.
