| Summary: | A review of machining with high speed (HSM) in use nowadays shows that it is one of the modern technologies that replaced conventional machining due to efficiency,
accuracy and machining time. In metal cutting process, the heat generated is acts as important factor that influences the performance of cutting tool. The high temperature zones resulting wear to the cutting tool that leads to flank wear and crater wear.
Therefore, it reduces tool life and affects dimensional accuracy. This study is focus on cutting performance of carbide cutting tool towards temperature using infrared radiation.
These methods include calibration, pyrometer and tool wear analysis. The use of a pyrometer has been examined in detail using a sensor of indium arsenide (InAs) and
indium antimonide (InSb). The experiment involved an analysis of the effect of changing the feed rate, varying the radial depth and varying the axial depth against tool
wear. The results showed that increasing the feed rate, radial depth and axial depth increases the cutting temperature and tool wear. An important factor in measuring temperature of cutting tool is calibration process of heated cutting tool and position of
the optical fiber towards cutting tool. A tool wear analysis has been conducted that shows that increasing the radial depth and axial depth with respect to feed rate increases the wear length which will increase the temperature. The results of this experiment and
tool wear analysis are presented such that can be used as an aid to improve the design of dry cutting. |
