Which milling process creates curved surface features by using multiple axes?

• A. Face milling
• B. Contour milling
• C. Slotting
• D. Straddle milling

Answer: (B)

Contour milling is the correct answer because it specifically involves the use of multiple axes to create curved surface features. This process allows for the manipulation of the cutting tool's position along different pathways, enabling the generation of complex geometries and contours in the workpiece. The cutting tool moves along a predetermined path that can follow intricate curves, making it ideal for producing rounded shapes or contours that would be difficult or impossible to achieve with simpler milling techniques. In contrast, face milling mainly focuses on flat surfaces by positioning the cutter perpendicular to the workpiece. Slotting is designed to create narrow slots or grooves and is typically performed on a single axis. Straddle milling involves using multiple cutters to mill two parallel surfaces at the same time, which does not facilitate the creation of curved features. Thus, contour milling stands out as the only method among the choices that effectively accomplishes the task of shaping curved surfaces using multiple axes.
