Stainless steel from a continuous dry milling by cutting variable described, beginning with an end mill with coating helix angle and size of different materials. Summarized as follows: -The shape and type of material coated with wear protection, influence both cutting edge and end mill cutting edge area of the side End mill coated with TiAlN. protection against wear better than helix angle DLC every flank wear and wear little helix angle up the helix angle is higher since motivated machining is less. They also found severe wear the chipping occurs at the sharp end mill cutter coated with DLC, which makes the end mill short tool life. -High End mill cutting with high helix angle while workpiece temperature high helix angle since a heat source for more than low helix angle. Likewise, the end mill coated with DLC while cutting workpiece temperature will be higher, since end mill TiAlN coated with DLC chipping occurs make machining is complete. Thus, the helix angle coating material influence. workpiece temperature. High helix angle there--that chip thickness is less than. Low helix angle is greater than the number of ACP since helix angle is different, and has different chip the shape. In addition, the high helix angle, color of gold ions will be cut because of some very talented chip react with heat sensitivity.-Surface roughness in machining trials, from the high end mill with helix angle DLC coating with but the service life of the end mill is so short end mill of this type are suitable for jobs which require high quality surface finishing milling and cutting the long length is not continuous. However, the helix angle for high end mill coated with TiAlN is able to control the stability of surface roughness surface roughness value and is not very high and therefore suitable for milling milling work general required a continuous long term.
