Lõiketööriista

Lõiketööriista is an Estonian term that translates to "cutting tool" in English. It broadly refers to any instrument or device designed to remove material from a workpiece through shearing, abrasion, or other cutting actions. These tools are fundamental across a vast array of industries, from manufacturing and construction to woodworking and everyday household tasks.

The design and function of a cutting tool are highly dependent on its intended application. For instance, tools used for metalworking, such as lathes, milling machines, and drills, employ hardened steel or carbide cutting edges to shape dense materials. Woodworking tools, like saws, chisels, and planes, are optimized for cutting fibrous materials, often featuring sharp, precisely ground edges. In more general contexts, knives, scissors, and blades are common examples of cutting tools used for softer materials like paper, fabric, or food.

The principle behind most cutting tools involves applying force to create stress concentrations at the edge of the tool, exceeding the material's shear strength. This can be achieved through various mechanisms including rotational motion, linear motion, or a combination thereof. The effectiveness and lifespan of a cutting tool are significantly influenced by factors such as material hardness, edge geometry, lubrication, and proper maintenance. Sharpening and replacement are common practices to ensure continued efficient operation and safety.
