- Abstract:
- The formation of the surface roughness during the machining of hardened steel, similar to the machining of “soft” materials, so far has been considered as a function of the cutting parameters (cutting speed, feed, cutting depth), the minimal chip thickness and the nose radius. Experimental results have not proved the theoretical calculations to be correct, and appeared to have a significant deviation. Actually the surface roughness is depending on the condition and roughness of the cutting edge to a great extent. Theoretical examinations can confirm our experience that a correlation occurs between the cutting edge roughness and the surface roughness. In our exposition we would like to explain our machining experiments, and theoretical examinations, which are mend to complexly expose the relations between the cutting circumstances and the surface roughness.
