When machining non-ferrous materials, climb cutting should be used to achieve a good finish. Speed & feed settings vary a lot from machine to machine, a lot of it is to do with how rigid the CNC machine is. For a MultiCam CNC router, our spindles will run up to 24,000 RPM, with some spindles reaching 30,000 and even 50,000 RPM. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. This speed is termed 'spindle speed' and is directly related to the feed rate or surface speed, which most machines are capable of doing up to about 200ipm. The next thing to be considered is the direction of cut, which is the direction the cutter is fed into the material. Chip Load Values for each Material and Bit Selection. Trochoidal/Peel Milling or Dynamic milling feeds and speeds. 1) Number or flutes (wings) 2) Feed Rate (feed speed) 3) RPM (spindle speed) The relationship between these three variables determines 'chip load,' which refers to the actual physical size of chip being cut by each flute.
