Difference between cutting speed and feed?

Certainly! Here’s a table summarizing the key difference between cutting speed and feed rate:

In this blog we will learn about the difference between cutting speed and feed rate in a table format

AspectCutting SpeedFeed Rate
DefinitionThe speed at which the cutting tool moves relative to the workpiece.The rate at which the cutting tool advances into the workpiece.
UnitTypically measured in surface feet per minute (SFPM) or meters per minute (m/min).Usually measured in inches per minute (IPM) or millimeters per minute (mm/min).
SymbolV or VcF
Effect on CutHigher cutting speed usually leads to faster material removal and better surface finish.Higher feed rate increases material removal rate but can affect surface finish and tool life.
RelationshipInversely proportional to tool life; higher cutting speed can decrease tool life.Directly proportional to material removal rate; increasing feed rate increases material removal rate.
ControlOften controlled by machine spindle speed or rotation speed of the cutting tool.Controlled by the rate at which the workpiece is fed into the cutting tool.
ApplicationCritical in turning, milling, drilling, and other machining operations.Crucial in determining machining time and achieving desired surface finish.
