The effectiveness of a machining process can be determined by analysing the quality generated surface and rate tool wear. Stellite is highly challenging to machine, which why it primarily processed through grinding methods. This study concentrates on impact cutting parameters wear (VBb, KBb) created roughness (Rt, Ra, Rz) during orthogonal 6, overlaid steel surface, C45, prepared means HP/HVOF (JP-5000). results indicate that dominant influence change in total profile height value (Rt)...
