1: Cutting depth, that is, the cutting depth of each layer;

It's like how thick you cut the radish with a knife!

This is a better understanding. Someone in a hurry to ask the teacher, how much do I have to deal with each floor?

Ask yourself. Because only you know the diameter of the tool. Your tools are 80 mm, 30 mm, 1 mm or even 0.3 mm.

What is the concept of 0.3mm, that is, three pieces of paper are stacked together, that is, the thickness of a business card. I used to grind a lot of 0.3 knives on the grinding bed.

You have to deal with these materials. You are making cakes or wood, aluminum or copper.

You can cut the cake with a plastic blade!

Just like you cut the wood with an ax. You cut 1 cm with an ax. 10 mm

Why don't you use an ax to cut iron? If you come, your knife will fall!

If you change a suitable ax, you can use it to cut iron.

2: The speed of the spindle, that is, the speed of the motor (also known as the motor) in the machine, the speed of the knife N.

Because this is a bit difficult to understand, I will help you understand.

The speed of the tool can be converted into a line speed. Because the tool is installed on the cart and rotated continuously, it is difficult to understand how fast it is. If it is a car, a bicycle, and a motorcycle, it is easy to understand. Because you have a better visual experience, you can even calculate how many kilometers per hour, how many kilometers per minute, and how many meters per second.
