Abstract

The aim of the work is to study the effect of cutting condition on cutting bit of the turning machine while working on different metal ,Through using a special type of commonly used cutting tool bit in (HSS) due to the high qualifications it is characterized by cutting ,and its endurance of high temperature .Two types of metal are used in cutting (Aluminum, Mild steel),relying on the working conditions used in the machine(feed, cutting speed، depth of cut),while conducting working processes via using cooling liquid ,and without it .The wear test results shown that there are two types of wear measured by the (tool micker microscope) :Flank wear and Greater wear, are formed on the cutting edge of the tool bits as a result of the great effect of cutting conditions on the tool bit and the high temperature of the chips ;in addition to the occurrence of resulting edge on the cutting edge of the tool bits in the process of cutting aluminum , with the use of cooling liquids which prolong the of cutting tool and decrease the periods of re-grinding the cutting tool bit
