PURPOSE:To reduce the ungrinding time so as to reduce the number of processes, and to decrease the processing cost, by stopping the executing traverse depending on the generation of traverse finishing signal in the traverse grinding process, and starting the traverse in the reverse direction. CONSTITUTION:After grindstone is moved in one direction on the X axis and a specific amount is cut depending on the cutting amount designated in a program, a traverse is started in one direction on Z axis to the point WN as the object point. And at the black circular points in the figure, the input traverse finishing signal is confirmed to stop the traverse operation, and when such a signal is not input, after confirming if the position on the Z axis of the grindstone reaches the object point WN, and confirming again if the traverse finishing signal is input, the traverse operation is stopped. And after confirming whether the position on the X axis of the grindstone reaches the directed cutting finishing position or not, the spark-out operation is carried out to finish the grinding. On the other hand, when it does not reach the point, the traverse in the reverse direction is carried out to continue the traverse grinding until the cutting finishing position is reached, and then the spark-out operation is performed to finish the grinding. |
