Machinability

Dictionary

The feed rate is the speed at which a component is moved along the machining axis during CNC machining such as turning, milling or drilling. The feed rate is usually measured in millimetres per minute (mm/min) or millimetres per revolution (mm/rev). Adapting the feed rate to the material is crucial to ensure high quality machining and optimum machine service life. As a rule, the harder the material, the lower the feed rate, as otherwise there will be high wear and poor surface quality.

Dictionary

Subtractive manufacturing refers to a manufacturing process in which material is removed from a blank using various techniques such as turning, milling or drilling to form the desired end product. This process is widely used in the metal, plastics and wood industries. It enables the precise production of complex components with tight tolerances and high surface quality. Subtractive manufacturing is essential for series production, prototyping and customization in manufacturing technology. By using modern CNC machines (computerized numerical control), efficiency and accuracy can be further increased, making companies more competitive.

Dictionary

Surface roughness measures the unevenness and texture of a surface at the smallest level. It is mainly measured by the height differences on the surface and is given in micrometers (µm). The mechanical properties strongly depend on the surface roughness as it influences friction, wear and functionality. Therefore, choosing the right surface roughness is also important for manufacturing processes such as CNC machining. The roughness is often improved by various finishing processes such as grinding and polishing.

Dictionary

In manufacturing, a workpiece refers to the basic blank or starting material that is shaped using various machining processes such as turning, milling or grinding. It forms the basis for the manufacture of an end product and can comprise metal, plastic or other materials. Workpieces are manufactured precisely according to technical drawings and specifications in order to achieve the desired dimensions and properties. The quality and accuracy of the workpiece is crucial for the functionality and durability of the finished product. In industry, the efficient machining of workpieces enables high production quality and contributes to the optimization of manufacturing processes.

Dictionary

Nesting is a type of optimization in sheet metal processing. Nesting involves arranging multiple parts on a single sheet as closely as possible in order to minimize material waste and thus the waste of resources. By using special nesting software, DXF files can be created to maximize the use of material. When arranging the parts on a single sheet, many parameters such as part geometry, cutting paths and machine thickness must be taken into account in order to achieve a real difference in resource utilization and costs.
