kuttehastigheter

Kuttehastigheter, also known as cutting speeds, refer to the velocity at which a cutting tool or workpiece surface moves relative to each other during machining operations. The term is commonly used in metalworking, woodworking, and plastic manufacturing to describe the speed of the cutting action. It is usually expressed in meters per second (m/s) or surface feet per minute (SFM). Accurate control of kuttehastigheter is essential for achieving desired surface finish, tool life, and dimensional accuracy.

In machining, the cutting speed is calculated using the formula: speed = π × diameter × feed rate ÷ time, where the diameter is the diameter of the cutting tool or workpiece. The desired speed depends on several factors, including material hardness, tool material, cooling and lubrication, depth of cut, and spindle horsepower. Machining guides and machining handbooks provide recommended speed ranges for common combinations of material and tooling. For example, high‑speed steel tools cut steel at about 150–200 m/s, while carbide tools can machine aluminium at speeds up to 300 m/s.

The importance of proper kuttehastigheter lies in balancing productivity and quality. Too low a speed can increase cutting time and may lead to excessive thermal distortion. Conversely, overly high speeds can cause rapid tool wear, work-hardened chips or even tool failure. Additionally, excessive heat generated at high cutting speeds can alter the microstructure of the workpiece, affecting mechanical properties.

Manufacturers of CNC machines and hand tools often provide recommended cutting speeds in their datasheets. Engineers use these guidelines in process planning to optimize performance while minimizing cost. In research, studies compare different cutting speeds to develop new tool materials and cooling strategies that extend tool life and improve surface integrity.
