cutting speed

In machining, cutting speed refers to the relative motion between a tool's cutting edge and the workpiece. It's a crucial factor in determining how efficiently material is removed. The speed at which new, uncut material is brought into contact with the tool is called the feed motion. Both cutting speed and feed motion need to be adjustable.

The amount of heat generated during cutting is influenced by shearing force and cutting speed. This heat can affect the tool's ability to cut, so temperature control is essential. The optimal cutting speed depends on the materials being cut and the tool itself, as well as machine rigidity and the depth of the cut. The development of high-speed steel in 1900 significantly increased machining capacities by allowing tools to operate at much higher speeds than previously possible.12
