What is a characteristic of contour milling?

Contour milling is characterized by its ability to create complex shapes in a workpiece. This process allows for the machining of non-linear features and intricate designs, making it suitable for parts with elaborate geometries. The cutter follows the contour of the part’s design, enabling the production of rounded edges, curves, and other detailed profiles that are not achievable with simpler milling techniques that are restricted to straight movements.

In contrast, other options suggest limitations that do not apply to contour milling. It is not restricted to only straight lines, nor is it limited to flat surfaces. Additionally, contour milling typically involves movement in multiple axes, allowing for more flexibility and precision in shaping various components. Therefore, the ability to produce complex shapes is a defining characteristic of contour milling, emphasizing its versatility in manufacturing and machining applications.
