Step 1
Which milling procedure is shown in FIGURE 1.1?
Answer
To determine the milling procedure shown in FIGURE 1.1, we first need to analyze the image. The milling procedure depicted involves a cutting tool that is engaged with the material. In up-cut milling, the tool rotates in the opposite direction to the feed of the workpiece, causing the cutter to enter the material at the bottom and exit at the top. In down-cut milling, the cutter enters from above, pressing down into the material.
In this case, the configuration suggests that the milling operation is one where the tool is rotating in a direction consistent with down-cut milling. Therefore, the correct answer is:
C. Down-cut milling
