Kind Code:
A
Abstract:
PURPOSE:To quickly and accurately shunt a working tool up to a desired position when the processing is interrupted by tracing the information of the previous time after storing the information obtained before interruption of the processing and then to move the tool quickly and accurately to its working position when the processing is started again. CONSTITUTION:A control part 1 gives a shift instruction to a drive control part 4 by an automatic start signal 11 and the function of an arithmetic part 3 in response to a working program command stored in a storage part 2. A work (not shown in figure) is processed for each executing block of he working program. When the processing is interrupted, a shunt start signal 12 is supplied to extract an interrupted block number of at the time of processing interruption out of an executing block number storage part 21. Then the interrupted block is adversely executed to shunt a tool based on the shunt information stored in a shunt information storage part 22. At the time of reprocessing, the processing is restarted by a restart signal 13 according to a working block. Thus the working blocks are carried out again after the interruption after the interrupted block is executed.
