Abstract

Magnesium is one the very important material light weight, especially in the field of the vehicle component, and the field of biomedical. Application of material magnesium and its alloy in the field of biomedical based on the magnesium characteristics which look very much like the nature of biocompatibility of bones in man and melted down within the body. Application material magnesium are also many developed by means of grown (implant). Magnesium alloy material has some of the more in the chemical nature and physics, but in the machining process a magnesium alloy known as combustible metal material type, especially during the machining process at high speed. The optimizing of machining process is necessary in order to maintain for not chip burning. In this research, the point angle, lubricant and drilling parameter were analysed to know their influence on the value of surface roughness, cylindricity and perpendicularity. On this research analysis support for new carried out using a Taguchi Method L18 consisting of 3 factors with 3 levels and 1 factors with 2 levels. The research results show that surface roughness is influenced by the significant contributions from the point angle 18.9 % and lubricant 14.5 %, where the point angle is 650 with lubricant of synthetic oil. The emergence of a nose radius tendency resulting in the increasing level subtlety. Cylindricity is influenced by an point angle 450 of the drilling process however, especially if there is an interactions of the feeding of 0.2 mm/rev and synthetic lubricant. The cutting edge accuracy led to a tangential force so that had an impact on their rotation stability and the cylindricity of drilling results. The value of perpendicularity of magnesium AZ31 in the drilling process however also carried out similar procedures are very much influenced by the cutting parameter of feeding that produces the significance of p = 0,044 , while the strongest significance will be happened if there were an interaction between feeding of 0,1 mm and synthetic lubricant to p = 0.041.
