Lõikekaaru

Lõikekaaru, often translated as "cutting curve" or "arc of cut," is a term used in technical drawing and engineering to describe a specific geometric line. It represents the boundary or profile of a material that has been removed or shaped by a cutting process. This can apply to various manufacturing methods, such as machining, milling, laser cutting, or even in architectural contexts where sections are removed from plans.

The lõikekaaru is not a physical line on the object itself but rather a representation on a two-dimensional drawing that indicates the extent of a cut. Its purpose is to clearly communicate to fabricators or builders precisely where and how material is to be removed or altered. By visualizing the lõikekaaru, one can understand the resulting shape and dimensions of the component after the cutting operation.

In technical drawings, the lõikekaaru is typically depicted using a specific line type, often a thin dashed or dotted line, to distinguish it from visible edges or construction lines. Its precise form depends entirely on the geometry of the cut being made. For instance, a straight cut would result in a straight lõikekaaru, while a curved cut would be represented by a curved lõikekaaru. Understanding the lõikekaaru is crucial for accurate interpretation of technical documentation and successful execution of manufacturing processes.
