EXPERIMENTAL INVESTIGATION OF EFFECT OF HEAT TREATMENT ON NOSE RADIUS OF INSERT AND TEMPERATURE AT CUTTING AREA IN TURNING OF TITANIUM (GRADE 2)

Titanium and Titanium alloys are utilized in many aerospace applications due to a combination of properties such as high strength at elevated temperatures and relatively low density. However, these materials are problematic to machine and are therefore referred to as difficult-to-cut materials. Compared to most materials, the chip–tool interface temperatures during machining are extremely high, even at lower cutting speeds, and tend to concentrate close to the cutting edge. These alloys when machined results in the reduced tool life and effects the surface roughness of the material. In this article to overcome the reduction in the tool life and development of the temperature at the cutting area the titanium is heat treated. The temperature at the cutting area in the turning is measured using Non-Contact Infrared Digital Thermometer and the nose radius of the tool insert is measured using profile projector.
