Inches per tooth to feet per tooth
WebTo find approximate RPM the old machinists would follow the formula: RPM= (CSx4)/D which is essentially the same as what we use today: RPM = SFM X 3.82 ÷ Tool Diameter, just without the division. The "SCS" ("SFM") is the cutting speed in feet per minute, 4 is a constant, and D is the diameter of the cutter WebFocus on on the proper feed per tooth (FPT), and then adjust the speed. Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter. ... Speeds - Inch. SFM = surface feet per minute. RPM = SFM X 3.82 / Tool Diameter. Speeds - Metric. SMM = surface meters per ...

WebOur Feeds Calculation is then 6112 * 0.001 * 4 = 6.112 * 4 = 24.448 inches per minute as our calculated feed rate. Exceeding that feed rate will likely jam the cutter with too many chips and potentially snap it off. You don’t want to slow down the feed rate too much because we want to avoid rubbing at all times.
