Through the analysis of the knife of the automatic tool changing process, so that the cutter in machining center can be matched with the tool changing manipulator needs -- in NC program under the control of flexible implementation tool changing process every time new knife only needs to input the corresponding tool change signal can be. The analysis and control on the basis of the requirements, designs the corresponding control procedure. The control program includes: establish the library image, recording request tool number, the rotation of the turntable direction judgment and to determine the turntable is reversed, to send pulses to control the cutter disc to rotate in place, lights and tool change indicator display parts, good program structure, readability is strong, operation efficiency is high ,which can meet the practical requirements.
