The grinding of single-start female thread by an abrasive wheel on CNC machine

The mathematical model of grinding the single$start outer thread by grinding wheel without tool spindle tilt is described. The technique of calculating the grinding wheel axial section is proposed. The control the possibility of manufacturing the thread with the required accuracy is carried out in the simulation processing thread by specified grinding wheel. Examples of the proposed technique application to grinding the trapezoidal thread are presented. It is shown that an increase of inner thread precision may be obtained by decrease of grinding wheel diameter or by increase of tool axis tilt.
