In addition to checking the wear of the cutting edge in research also checked for wear at cutting side edge that has the same importance in the side milling process. From Figure 8 (a), (b), (c) cutting. TiAlN coated side edge of the helix angle showed the wear and flank wear, but the magnitude is different. Figure 9 shows the wear of flank wear on high helix angle range will be less wear and tear. The helix angle 600 will have Vbmax minimal due to a helix angle, so the force of the cutting action causes less wear than the helix angle other. This is different from the cutting edge with little strength. As discussed in earlier. And also wear a little chipping on the cutting edge with a helix angle 300. show that the size of the helix angle influence the wear of the cutting side edge as well as cutting edge. However, end mill coated with TiAlN still capable. To prevent wear of the cutting side edge than DLC. According to Figure 8 (d), (e), (f) found wear chipping on the cutting side edge all coated with DLC. As a result, fragments cut into the mask. milling around the side cutting edge end mill can not be cut further in Figure 10.
Figure 10 is a marvelously in this trial build up side edge end mill with all DLC coated. The research has a number of explanations that DLC possesses outstanding one is an excellent anti-adhering property. (Haruyo Fukui. Et al, 2004: Robertson J, 1999: Yunn-Shiuan Liao. Et al, 2014). It is because of this research, experimental milling continued long made this property does not appear. The helix angle 600 a mask attached fastest short-cut over 30 m due to the size of a higher helix angle will result in higher workpiece temperature increases. (Which is described in the workpiece temperature). The lifetime of the end mill is just milling over 30 m only. Unlike end mill with a helix angle 300, 450 caused a build up side edge when undergoing cuts through 50 m. In turn, end mill. All TiAlN coated with helix angle to prevent build up side edge due to the properties of TiAlN mentioned above.
