Gray cast iron in engineering is usually called ferro cast and this material can not be separated by the manufacturing industry. Cast ability, high able to absorption of vibration, and economic which makes gray cast iron a superior material.Compared to other materials, FC-150 has many advantages such as low impact strength, vibration damping, generates low cutting forces, good thermal conductivity, and excellent machinability.Wear and tear occurs in the cutting process only by abrasion, small heat generated during engine operation and the cutting process and have a little cavity and a little shrinkage porosity[1]. The problem is that the cutting tool for cutting FC-150 has a short life time.The oxide tool inserts researchreveals and answersthe FC-150 cutting tool problematic. This study begins by identifying the solid cylinder specimen (FC-150) produced under a lathe process with an OTI cutting tool. First, set up the solid cylinder and tool respectively on the chuck and the tool post. Secondlyset the independent variables, which are the spindle rotation, feed rate and depth of cut. The data observed was the dependent variables which are the cutting tool temperature, cutting force andworkpiecesurface roughness. The last step of this research is by combining the data analyzed and correlating statistically the specimen data (physical, mechanical and metallographic). In general it is indicated that, when the cutting speed increases the roughness would decreases, so does when the cutting feed is less(f) then Ragoes down. From this research the cutting speed result is 390,56 m/min, the feed rateis16 m/rev, the depth of cut is 0,8 mm which is producingthe smallest roughness of 0,69 μm, and was categories in grade N7 on the ISO 1302 Standard Roughtness Number,which means a smooth surface result. Which was take place on the use of the oxide tool insert Cr2O3,TiO3. © Research India Publications.
