METHOD FOR AUTOMATIC RETURNING OF AUTOMATIC TOOL EXCHANGER

摘要

PURPOSE: An automatic returning method of an automatic tool exchanger is provided to enable a worker to finish tool exchange and to return to work by automatically informing the worker of the currently closest returning way through internal calculation in error generation due to an abnormal pause during operation. CONSTITUTION: An automatic returning method of an automatic tool exchanger comprises the following steps: converting to an automatic returning screen when the operation of an automatic tool exchanger is abnormally paused(S120); grasping a current position and determining the step of a current abnormally paused position for the automatic tool exchanger based on a table in which the operation process of the automatic tool exchanger is classified by steps(S140); and determining to return to a forward or backward step from the determined step(S180).
