effects of speed change on milling operation
Cutting speed may be defined as the rate at the workpiece surface irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece such as in a turning operation or the speed of the cutter moving past a workpiece such as in a milling operation.
