Cutting feed rate
The speed at which the cutting tool moves across the workpiece. It must be precisely matched to the energy input and sheet thickness to ensure low-friction cuts.
Physical-Chemical Mechanism of Action
The flame cutting feed speed affects the friction between the tool and the sheet. Too high a speed increases friction, causing more energy loss and faster tool wear. Too low a speed can lead to uneven cuts or even tool failure.
Metallurgical Relevance & Risks in Welding
An inappropriate feed speed can lead to the following problems: overheating of the workpiece, deformation, uneven cut depth, and shortened cutting tool life. This increases the risk of cracks or failed work.
Workshop Practice & Action Instructions
The feed speed should be set according to the material and sheet thickness. For steel sheets with a thickness of 2 mm, a speed of about 10 m/min is typical. For thinner or harder materials, the speed can be adjusted to achieve optimal results. It is important to continuously monitor the speed and adjust as needed.
