What function do T-slots serve in a machine table?

T-slots in a machine table primarily serve the function of allowing for clamping workholding components. These slots are designed to accommodate T-bolts or other fastening mechanisms that can be slid into the slot and tightened down, securing various fixtures and workpieces to the table during machining operations. This clamping ability is essential for maintaining the stability and precision of the workpiece throughout the cutting process, thereby ensuring quality and accuracy in the final product.

While other options suggest possible functions, they do not accurately represent the primary use of T-slots in machining tables. T-slots do not provide tool storage, support cooling systems, or adjust the height of the table, which are functionalities associated with different components or design features in machining setups.
