Which grouping of processes uses a single- or multi-point tool to remove metal from a workpiece?

The correct grouping of processes that utilizes a single- or multi-point tool to remove metal from a workpiece is metal cutting. This process is fundamental in machining where the primary goal is to achieve the desired shape and finish by removing excess material from a solid block of metal. Metal cutting processes include techniques such as turning, milling, drilling, and grinding, each employing specific tools for efficiency and precision.

In metal cutting, the tool interacts with the workpiece at a controlled angle and speed, enabling the removal of material through shear deformation. This process emphasizes the importance of tool design, material properties, and cutting conditions to achieve optimal results in terms of surface quality and dimensional accuracy.

The other processes mentioned do not focus primarily on the removal of metal through cutting. Metal shaping often involves forming processes without cutting, such as forging or bending. Metal casting involves pouring molten metal into a mold to solidify into the desired shape, which does not utilize tools to remove metal. Metal forming refers to processes that deform material without cutting, such as rolling or pressing. Understanding these distinctions highlights why metal cutting is the correct answer for processes that involve the removal of material using cutting tools.
