What is the primary goal when using a dial indicator for alignment on a mill?

• A. To set the tool height
• B. To ensure precision placement of the vise
• C. To measure workpiece thickness
• D. To check tool wear

Answer: (B)

The primary goal of using a dial indicator for alignment on a mill is to ensure precision placement of the vise. A dial indicator provides a direct measurement of any discrepancies in alignment by allowing the operator to detect small deviations from a desired position. When setting up the milling machine, it’s crucial for the vise to be aligned accurately relative to the spindle or cutting tool, as this affects the precision of any workpiece being machined. Using the dial indicator, the operator can adjust the position of the vise until the measurements indicate that it is correctly aligned. This level of precision is essential in machining processes, as it helps avoid issues such as uneven cuts or misaligned features that could compromise the integrity of the workpiece or lead to costly errors. The other options, while they may relate to machining in various ways, do not directly pertain to the specific function of a dial indicator in alignment tasks on a mill. Setting tool height is important, but it typically involves other devices. Measuring workpiece thickness generally requires different tools or instruments. Checking for tool wear, while necessary in maintenance practices, does not relate to vise alignment in the same manner as ensuring its precision placement does.
