Answer 1

1

1. In a milling machine the cutter is a circular device with a series of cutting edges on its circumference.
2. The table has three possible movements: longitudinal, horizontal, and vertical. In some cases it can also rotate.
3. Flat or contoured surfaces may be machined with excellent finish and accuracy.
4. We use a drilling machine to drill or enlarge holes. It can also be used to cut threads for a screw or a smooth finish of a hole.
5. A single-point cutter is rotated while boring.

• flat or contoured surfaces
• to remove metal
• vertical
• a grinding machine
• to be different in size and function
• fragile materials
• a circular device
• to rotate
• the tool slides
• for workshop where flexibility is important
