To solve for distance use the formula for distance d = st, or distance equals speed times time. distance = speed x time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means ...

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.
