Lõikamisjõud

Lõikamisjõud is an Estonian term that translates to "cutting force" in English. It refers to the force required to cut or shear a material. This concept is fundamental in various fields, including manufacturing, material science, and engineering.

In machining processes like turning, milling, or drilling, cutting force is a critical parameter that influences tool wear, surface finish, and power consumption. It is influenced by factors such as the material's properties (hardness, toughness), the cutting tool's geometry (rake angle, clearance angle), cutting speed, feed rate, and depth of cut. Understanding and controlling cutting forces is essential for efficient and precise material removal.

The measurement of cutting force is typically done using a dynamometer, which can quantify the forces acting on the cutting tool. These measurements help in optimizing cutting parameters, selecting appropriate tools, and predicting tool life. High cutting forces can lead to increased tool wear, potential workpiece deformation, and require more powerful machinery. Conversely, excessively low forces might result in poor surface finish or inefficient material removal.

In structural engineering, the term "lõikamisjõud" can also refer to shear force, which is a force acting parallel to a surface. This is important in analyzing the behavior of beams, columns, and other structural elements under load. Shear force causes internal shearing stresses within the material.
