Abstract

Magnesium is one of important materials light weight, which is used world widely, especially in the field of the automotive, sport, electronic and 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 the body. Application material magnesium is also many developed by means of implanting in the body to replace the bone. Magnesium alloy have some advantages as like good strength-to-weight ratio, good biocompatible, good thermal conductivity and resistant to corrosion. However, magnesium known as flammable material, especially during the machining process at high cutting speed. The objective of paper is to optimize machining process and to maintain the chip is not burning. In this research, the point angle, lubricant and drilling parameter were analyzed to know their influence on the value of surface roughness, cylindricity and perpendicularity. On this research analysis support be done by using a Taguchi Method L18 consisting of 3 factors with 3 levels and 1 factors with 2 levels. The experimental 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 nose radius of cutting tool tend to increase the force when cutting process. The drilling process effected on cylindricity of hole, mainly by point angle of 450, however, especially if there is an interactions between the feeding of 0,2 mm/rev and synthetic lubricant. 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/rev and synthetic lubricant to p = 0,041
