Surface Roughness of Steel in Turning with Metal Buildup on the Tool

Resumo

In the machining of steel, metal from the workpiece may build up on the tool’s cutting edge. The influence of such buildup on the roughness of the machined surface in the turning of 40Х steel is simulated. The cutting conditions and the tool geometry are found to affect the surface roughness. The adhesive properties of the machined material are also significant. Vibration in the machine tool does not have a statistically significant influence on the surface roughness. That may be attributed to the rigidity of the equipment employed.
