Which machining process produces a surface based on the tool's profile?

The forming process is distinct because it creates a surface that mirrors the exact profile of the cutting tool used. In this process, the workpiece material is reshaped through the application of force, often using a tool that has a specific shape or contour. As the tool makes contact with the material, it effectively stamps or molds the material into the desired configuration, resulting in a surface that directly reflects the tool's profile.

In contrast, generating processes are characterized by a motion where the tool moves in a path relative to the workpiece, leading to surfaces that can be produced by various cutting motions. Turning involves the workpiece rotating while the tool moves in a linear path, which does not inherently rely on the tool's profile for surface formation. Drilling creates holes more so than surfaces and is intended for different machining objectives, focusing on creating cylindrical features rather than replicating a tool profile on a surface. Therefore, forming is the process that uniquely produces surfaces based on the profile of the tool.
