Understanding cutting equations | Cutting Tool Engineering

The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter ×, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and is a constant that comes from an algebraic simplification of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). Because the tool diameter is ...

Speeds and Feeds Calculator | Formula

The term "feeds" refers to the feed rate or the relative linear speed between the tool and the workpiece. For example, for drilling, it is the speed at which the drill bit travels down into the workpiece material. The equation for the feed rate is: small f = Ntimes C_mathrm {L}times n_mathrm {t} f = N × C L × nt.

Optimizing feed rates and speeds: 1. Start off using an RPM derived for the chip load for the material being cut (see charts). 2. Increase the cutting speed (feed rate) until the quality of the part's finish starts to decrease or the part is starting to move from hold downs. Then decrease speed by 10%. 3.
