the power needed for a machining operation. Power can be calculated from P = hp (horsepower) where Fc is in lb, V in sfpm, and E = mechanical efficiency of the machine (typically around 90%). F.V 33,000-E - the load which the tool, machine and workpiece must be able to withstand during machining. The inability to withstand this load can result in a broken tool, a damaged part, and/or deflection in the machine (and hence the inability to accurately machine items).
