What is Spindle Speed?
Spindle speed is the rotational frequency of the machine's spindle, measured in revolutions per minute (RPM). It is directly related to the cutting speed, which is the speed of the tool's cutting edge relative to the workpiece. To achieve a desired cutting speed for a specific material and tool, you must calculate the correct spindle speed based on the tool's diameter.
Formula Used: `n = (Vc * 1000) / (π * D)`, where `n` is spindle speed in RPM, `Vc` is the desired cutting speed, and `D` is the tool diameter in mm.
