Practical Measurement and Evaluation of Thermal Behavior of NC Lathe and Its Application to Turning Process Modification
The measuring method for thermal effects in NC machine tools was drawn drawn-up as ISO 230 230-3 in 2001. After that, this international standard was introduced as JIS B 6193 in 2003. In connection with this, the measurement of thermal effects becomes achievable als also not only in a machine tool o builder but in a user side. Therefore, in this research, practical measurement and evaluation of thermal behavior in CNC lathe are performed from a users viewpoint. Primarily in the experimental NC measurement, the spindle speed required for turning of the workpiece for a trial trial-production was given as a load pattern. Then the thermal displacement between cutting tool and workpiece was measured based on the above above-mentioned standard and the evaluation result was reported. Secondaril Secondarily, the y, consideration was done for the modification of the turning process of the most influential thermal effect. The thermal behavior by applying the modified load pattern was re re-measured successively, and comparative evaluation was carried out. As a resu result, it was verified that an extensive reduction of the lt, thermal effects was possible in the sensitive direction to the accuracy.
