Automated, mechanized table movement on a milling machine, driven by a motor and often controlled electronically, allows for precise and consistent material removal. This automated movement contrasts sharply with manual handwheel operation, where the machinist directly controls the table’s position. For example, a programmed feed rate can consistently move a workpiece past a cutter at a specific speed, ensuring uniform depth of cut and surface finish.
This automation contributes significantly to machining efficiency and accuracy. It reduces operator fatigue, particularly during long or complex operations, and frees the machinist to focus on other aspects of the process. The consistent, predictable motion results in better surface finishes, tighter tolerances, and increased production rates compared to manual feeding. Furthermore, the development of these systems has played a vital role in the evolution of milling from a labor-intensive process to the highly automated machining centers common in modern manufacturing.
