Which machine uses linear relative motion between the workpiece and a single point cutting tool to machine a linear tool path?

• A. Is a type of machine tool that uses linear relative motion between the workpiece and a single point cutting tool to machine a linear tool path.
• B. A drill press used for holes.
• C. A lathe that rotates the workpiece.
• D. A milling machine with multi-axis capability.

Answer: (A)

A lathe. In turning, the workpiece rotates while a single-point cutting tool feeds in a straight line, producing a linear cut path along the length of the part and forming a cylindrical surface. This combination of rotational workpiece motion with linear advancement of a single-point tool is the hallmark of turning on a lathe. A drill press is used for holes with a rotating drill, not a single-point tool creating a linear surface path; milling uses multi-point cutters and multi-axis motion for more complex paths; and a milling machine with multiple axes isn’t described by a single-point, linear-cut setup.
