Prediction of Surface Roughness through Measuring Runout in High-speed Ball-End Milling

In this study the runout of spindle is selected as a parameter through which we could measure the machinability of machine and the quality of products. We experimented the effects of runout on surface roughness in high-speed ball-end milling by cutting HP4M workpiece in various cutting condition. It was founs that sunout makes a directive effects on surface roughness and the frequensy type of runout is more or loss similar with that of surface roughness. So the predcition of surface roughness could be possible through measuring the spindle runout.
