The final surface roughness obtained by machining operation is very important in finish cut. One of the main factors relating to the surface roughness is the formation and destruction of built up edges. It is clear that their fragments increase the surface roughness. Orthogonal cutting method is used in order to obtain the obvious relation between cutting speed and surface roughness. Cutting speed is changed from 5 m/min to 200m/min in this experiment. Built up edges are frozen and observed using quick stop device of cutting by explosive. The conclusions attained are as follows. 1. The maximum surface roughness is determined by the size of the remained fragments of built up edge on the machined surface in the low cutting speed range. 2. Cutting speed, the size of built up edge and fluctuation of cutting force affect the surface roughness directly and indirectly.
