Cutting data of end mills and indexable tools
 

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)

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 cutting speed (Vc) can be calculated from the outer diameter (Dc) and rotational speed (min⁻¹) of the tool.

What is the feed rate of a drill?

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

What is rotational speed?

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

Basics and Calculation Formulas for Cutting Data

The cutting data determines how fast the tool should be rotated or moved.
In order to process with a machine, it is necessary to set the "speed of rotation" and "speed of movement" with specific numbers.
In the NC code of the machine, the speed of rotation is represented by S and the speed of moveme

answer

It can be calculated using the following calculation method.

Vf (feed rate) = fz (feed amount per blade) × z( number of flutes ) × n (rotational speed)

 

number of flutes : Please check from the specifications of your indexable cutter or end mill.

Rotation speed (n): It can be calculated from the

The catalog condition table is an efficiency-oriented condition.

If you value more stable machining and tool life, we recommend the following adjustments.

・ Check the cutting conditions (rotation speed) of drills and taps from the bottom of the condition range in the catalog.

The amount of feed per rotation of the drill (mm/rev) is likely to affect the shape of the
