摘要

During the machining process, a few cutting parameters are implemented such as cutting speed, depth of cut, and feeding speed. Variation of cutting speed beside affect the result of machining also could affect the rise of temperature during the machining process. In this study, carbide and ceramic cutting tool was used to see the comparison of temperature growth between two different tools. Tool temperature was estimated by simultaneous temperature measurement using K-type thermocouple and a digital thermometer to measure on tool temperature. Experiments were carried out in dry machining using workpiece material of AISI 4340 alloy steel. A DNMG 150404HQ CVD-coated carbide insert and the ceramic insert was used during the turning process. The result of the experiment show The highest measured temperature value on carbide cutting tool was 114°C at 240 m/min cutting speed while the lowest temperature value was 87.8°C at 160 m/min cutting speed. While on the ceramic cutting tool the highest measured temperature value is 52,5°C at 240 m/min cutting speed and lowest is 47,5°C at cutting speed 160 m/min.
