During cutting there is only one main motion, such as the rotational motion of the milling cutter during ___________.

• Milling

• Drilling

• Turning

• Molding

In _____________ operation, the workpiece rotates. (write your answer in English)

在_____________操作中，工件旋转。（用英语写下你的答案）

In _____________ operation, the milling cutter slides and rotates at a time. (write your answer in English)

在_____________操作中，铣刀一次滑动和旋转。（用英语写下你的答案）

In cutting motion, the main motion has the highest speed and consumes the _______ power.

• highest

• lowest

• average

• no power

The relative motion between the cutting tool and the workpiece is called __________.

• Feed rate

• Cutting motion

• Depth of cut

• Rake angle

The relative motion between the cutting tool and the workpiece is called __________ motion.

The relationship between the main cutting speed VC, feed speed vf, and cutting speed ve in the figure is

• Ve = Vc + Vf

• Ve = Vc - Vf

• Vc = Ve + Vf

• Vf = Ve + Ve

During the cutting process, there are usually three constantly changing surfaces on the workpiece (choose three answers)

• Machined surface

• Surface to be machined

• Cutting tool surface

• Machined surface (transition surface)

Cutting amount refers to the sum of various parameters during cutting. (choose three options).

• cutting speed

• depth of cutting

• cutting tool angle

• feed rate
