Pengaruh Tebal Potong terhadap Umur Pahat Bubut HSS yang Dilapisi Titanium dan Nitrogen dengan Teknik Sputtering DC
Abstract: To increase
performance of tool life, it can be done by superhard coating on surface of
cutting tool by using sputtering method. The research aim was to deposit
titanium and nitrogen thin film on high speed steel surface, and to
investigate the effct of depth of cut on
tool. Thin film deposition was done by
sputtering in vacuum chamber and flowed argon and nitrogen simultaneously.
Formed thin film at 27 specimens were
tested by micro hardness Vickers of 10 gf. Optimal condition of temperatures,
times and gas ratio N2:Ar of sputtering were used to coat 54 tools. Testing of tool life were done by cutting medium carbon steel by
cutting depth 0,5; 1,0; I,5 mm, feeding 0,084; 0,090; 0,112 mm/rotation and
cutting speed 23; 28; 32; 36; 42 and 48 m/min. The results show that the
optimal depth of cut of coated and uncoated tools were 1 mm, tool life and
removal material were after coated titanium and nitrogen increased at 17% dan
40,3%, respectively.
