For milling and indexable tools, the following three numbers are required:
(1) Rotation speed (min-1)
How many revolutions per minute .
In NC code, it is expressed by "S". Example: 300 revolutions per minute = S300
(2) Feed speed Vf(mm/min)
D stands for tool diameter.
It is expressed as several times the depth and length of the tool diameter, and is expressed as ○○D.
In drills and end mills, it is expressed as many times as the outer diameter of the tool, and in Tap , it is expressed as several times as the outer diameter of the thre
What is flute length ?
What is a shank with a tongue?
It is a shank with two flat sides at the end of the shank.
What does cutting speed mean?
Cutting speed is the speed at which the outermost part of the tool moves in one minute.
Symbols are denoted by Vc. The unit is (m/min).
The feed rate is the number of millimeters that the tool moves in one minute.
The unit of feed velocity (Vf) of the drill is (mm/min).
The feed rate can be calculated by multiplying the rotation speed listed in the catalog by the feed amount.
The feed amount is the distance of how many millimeters the tool has traveled in
Rotational speed means how many revolutions the tool makes in one minute.
In the machining program that moves the machine tool, it is expressed by "S". In calculations, "n" may also be used. The unit is (min⁻¹). Example: S2000 → 2000 revolutions in 1 minute
The expression of the speed of rotation is different from t
