Research Abstract

This research work has proposed a new method to evaluate the performance of the machine tools analyzing the surface profile of the finished work piece by a single point tool.(1)The radial motion of the spindle axis decides the critical surface roughness in both turning and facing operation.(2)The motion of the rolling elements of the bearings and the vibration of the spindle affect to the surface roughness.(3)The axial error motion of the spindle affects to the surface roughness of the face of work pieces, and the thermal expansion also affects to the shape of the finished work pieces.(4)The squareness between the spindle and the table was evaluated through the measurement of the difference between the depth of the valley of the surface profiles produced by the front tooth and rear tooth by the fly cutting operation.(5)The table feed speed can be accurately measured instead of the laser interferometer by measuring the pitch of regulary generated tooth marks.
Through this study, it was found that the geometrical accuracy such as the squareness of the spindle and the table, rotational error motion of the spindle as well as the accuracy of the feed speed and the magnitude of the thermal expansion can be evaluated by the measurement of the roughness profiles of the finished work piece.
