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

• Milling

• Drilling

• Turning

• Molding

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）

(a)  

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）

(a)  

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 (a)   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
