Today's high-speed cutting is defined as what?

For high speed cutting to some extent the discussion is confusing. The definition of high-speed cutting, there are many views, many mysteries and many methods and many ways. Let us look at a few of these definitions:

In the following discussion of impact of high-speed cutting process parameters. From a practical point of view is very important to describe the high-speed cutting, it can also be applications for high-speed cutting provides practical guidelines.

The actual cutting speed

Because the cutting speed depends on the spindle speed and tool diameter, high-speed cutting shall be defined as "actual cutting speed" is greater than a certain level - cutting speed and conventional cutting linear relationship between cutting speed.

Exception is when the aluminum and other nonferrous metals in the cutting and finishing of all materials and ultra-finishing processes, in the hardened tool steel in the high-speed cutting performance.

Vf = fz × n × z

Shallow depth of cut

Very necessary and a typical application of high-speed cutting depth of cut ae (radial depth of cut) and ap (axial depth of cut) and the average chip thickness hm much smaller compared with the conventional cutting cutting. Q than conventional metal removal rate and therefore small. Exception is that in the aluminum and other nonferrous metals in the cutting and finishing of all materials and super finishing operations.

Q = ap × ae × Vf [cm3/min]
