lõikesügavuse

Lõikesügavus refers to the depth to which a cutting tool penetrates into a material during machining operations. It is a critical parameter in processes like milling, turning, and drilling, influencing factors such as material removal rate, tool wear, surface finish, and workpiece temperature. Understanding and controlling lõikesügavus is essential for achieving desired machining outcomes and ensuring the longevity of cutting tools.

In milling, lõikesügavus is the perpendicular distance from the cutting edge of the milling cutter to the surface of the workpiece that is being machined. For turning, it represents the radial depth of cut, the difference between the initial and final workpiece radius. In drilling, lõikesügavus refers to the axial depth the drill bit penetrates into the material.

Selecting an appropriate lõikesügavus involves a trade-off. A larger lõikesügavus generally leads to a higher material removal rate, speeding up the machining process. However, it also increases the load on the cutting tool, potentially leading to faster tool wear, increased heat generation, and a rougher surface finish. Conversely, a smaller lõikesügavus results in slower material removal but can improve surface finish and extend tool life. Machine tool rigidity, cutting tool material and geometry, workpiece material properties, and desired surface quality all play a role in determining the optimal lõikesügavus.
