What process is defined as a basic, chip-producing method using a blade with teeth to create a narrow opening in material?

The process described is sawing, which involves using a blade with sharp teeth to cut through material and create narrow openings. Sawing is commonly employed in various applications, including woodcutting and metalworking, and is characterized by the creation of chips as the teeth of the blade remove material in a linear fashion. The teeth on the saw work by penetrating the surface of the material, pushing the chips out of the cut, and allowing for controlled depth and width of the opening being made. This method is fundamental in shaping and sizing materials, making it an essential part of manufacturing and construction processes.

In contrast, milling involves rotating a cutting tool to remove material from a workpiece, which produces chips but is not primarily defined by a saw blade with teeth. Drilling typically involves a rotating bit to create holes, rather than making openings that run along a surface, and turning is a lathe operation where a single-point cutting tool removes material from the outer diameter of a rotating workpiece. Thus, the attributes of sawing distinctly align with the characteristics mentioned in the question.
