Step 1
Which milling procedure is shown in FIGURE 1.1?
Answer
The milling procedure depicted in FIGURE 1.1 is an example of Down-cut milling (option C). In down-cut milling, the cutter rotates in the same direction as the feed of the material, allowing for a cleaner cut and better surface finish, which is visible in the operational setup shown.
