METHOD FOR REPORTING STATUS OF NUMERICALLY CONTROLLEDMACHINE TOOL

摘要

PURPOSE:To make the titled machine quickly correspond to the change of the status of a numerically controlled machine tool and to reduce load by read ing out the status, comparing the status with the precedently read status and if any change is detected, reporting the status to an upper controller. CONSTITUTION:A numeral control device B1 or a machine interface device D is provided with a status reading means M1 and a stats reporting means M2. The status of a numerically controlled working machine tool C is read out by the means M1 and compared with the precedently read status, and if any change is detected in the status, the status is reproted to the upper control ler A by the means M2. Consequently, the the machine can correspond to the change of the status quickly and it is unnecessary to request a status report, so that the load of the upper controller and the transmission load of a communi cation line can be reduced.
