The cutting speed (v) is the speed at which a tool cutting edge is guided through the material to be machined in the cutting direction during material machining (e.g. milling) and removes a chip in the process. The cutting speed V is specified either in metres per minute [m/min] or metres per second [m/s]. The cutting speed depends on the diameter of the tool used d x π (3.14159...) and the speed of the drive machine (n) in revolutions per minute [min-1].
You can now easily calculate the cutting speed offline with our free Excel speed calculator.

The term speed is used synonymously with the terms drive speed and rotational frequency. The drive speed/speed (n) is specified in revolutions per minute [min-1]. The required speed is calculated from the cutting speed in metres per second [m/s] or in metres per minute [m/min] and the diameter of the tool d x π (3.14159...).

Revolutions per minute (rpm) is the number of complete revolutions of a shaft or similar in a period of 60 seconds and is a unit of mechanical speed.
The formula for calculating the speed is as follows:

The rotational speed (also drive speed, rotational frequency or rotational frequency) indicates the number of preferably mechanical rotational movements of a rotating body in a certain time.
A frequent point of contact with the rotational speed is the car, where the rev counter is often found as an instrument in the cockpit.
The drive/rotational speed (n) is specified in revolutions per minute [min-1]. The required speed is calculated from the cutting speed in metres per second [m/s] or in metres per minute [m/min] and the diameter of the tool d x π (3.14159...).

The peripheral speed or cutting speed (Vc) is calculated using the following formula:
The peripheral/cutting speed (v) here is the speed at which a tool cutting edge is guided through the material to be machined in the cutting direction during material machining (z.B. when milling) and removes a chip in the process.
The peripheral/cutting speed (v) is specified either in metres per minute [m/min] or metres per second [m/s].
The cutting speed depends on the diameter of the tool used d x π (3.14159...) and the speed of the drive machine (n) in revolutions per minute [min-1].

The feed rate is specified in millimetres per minute (mm/min) and is the speed at which the tool is pushed through or over the workpiece (##########). a hand router). The feed rate has a major influence on the surface of the workpiece.
The feed rate is calculated from the distance travelled by the tool in the feed direction relative to the workpiece per unit of time.
Here is the appropriate formula: vf = fz - Z - n (mm/min) Information on further formulae can be found here.

Vc in milling stands for the cutting speed. The cutting speed can be specified both in m/min and in m/s.
The cutting speed (Vc) is the speed at which a tool cutting edge is guided through the material to be machined in the cutting direction during material machining (milling) and removes a chip in the process. The cutting speed (Vc) is specified either in metres per minute [m/min] or metres per second [m/s]. The cutting speed depends on the diameter of the tool used d x π (3.14159...) and the speed of the drive machine (n) in revolutions per minute [min-1].

The peripheral speed, also known as cutting speed (Vc), is the speed of the outer circular line.
The circumferential/cutting speed (Vc) is specified either in metres per minute [m/min] or metres per second [m/s]. The cutting speed depends on the diameter of the tool used d x π (3.14159...) and the speed of the drive machine (n) in revolutions per minute [min-1].

The rotational speed of a rotating object is a main component in the frequency spectrum of the mechanical vibrations or acoustic noises generated by the machine. The rotational speed can be determined by measurement using microphones, strain gauges, acceleration sensors or similar instruments.
Example: car:
At the crankshaft of a car, the speed of this z.B. is measured via an inductive sensor and displayed in the car's cockpit.
You can easily find out how the speed is calculated here or calculate it directly here.
The milling speed (n) is calculated from the cutting speed in mm/min (Vc), the milling cutter diameter (d) and the circle number (pi).
Further information on the formula and an example calculation can be found here and our speed calculator can be found here.
The cutting speed (Vc) is the speed at which the tool cutting edge removes the chip from the workpiece. It should not be confused with the feed rate or the tool speed.
Further information on these formulae and an example calculation can be found here.
The cutting speed (Vc) is the speed of the moving cutting edges. It is calculated from the speed of the milling machine (n) and the diameter of the milling cutter (d).
It is important that this is not confused with the feed speed or the tool speed. Alternatively, the cutting speed can also be calculated using the angular speed.
To select the correct cutting speed, the composition and strength of the material to be machined, the toughness and hardness of the cutting material used and the desired dimensional accuracy and surface quality must be taken into account.
On a purely mathematical level, the cutting speed is influenced by the tool diameter (d) and the rotational speed (also known as the drive speed, rotational frequency or orbital frequency).
You can find out how to calculate the correct cutting speed and how to apply the formula here. You can calculate the correct cutting speed directly here.
The cutting speed, which is specified in m/min or m/s, is the speed at which a tool cutting edge is guided through the material to be machined in the cutting direction during material machining (milling), thereby removing a chip.
The speed (n), on the other hand, is specified in revolutions per minute [min-1]. It indicates the number of preferably mechanical rotational movements of a rotating body in a certain time.
The speed is calculated from the cutting speed in metres per second [m/s] or in metres per minute [m/min] and the diameter of the tool d x π (3.14159...).
