What is the best technique for milling on a vertical mill without an automatic table?

• A. Climb mill
• B. Conventional mill
• C. Vertical raise
• D. Power feed only

Answer: (B)

When milling on a vertical mill that lacks an automatic table, conventional milling is often considered the best technique. In conventional milling, the cutting tool rotates against the direction of the table feed. This means that the cutter comes into contact with the material at the top edge, generating upward forces. This method helps to secure the workpiece and can prevent the cutter from digging into the material too aggressively, which is particularly advantageous when operating a machine manually. Using conventional milling can result in improved control over the milling process, especially for manual operations where the operator must make adjustments continuously. This technique provides a smoother cut and better surface finish when working with harder materials. Additionally, in the absence of an automatic table feed, the slower rates of material removal associated with conventional milling can reduce stress on both the tool and the machine, enhancing the longevity of the equipment. Other techniques like climb milling have specific advantages but generally are better suited for machines equipped with automatic feeds that can handle the increased forces involved. On a vertical mill without automatic capabilities, ensuring steady control and a secure cutting process with conventional milling is often the preferred choice.
