Abstract

PURPOSE: To realize not only an automatic teaching but a high-accuracy play back working, by installing a device which detects both the working state and the tool position of the machine tool at all times and then converts them into the NC command information.
CONSTITUTION: A constant supervisory is given via the machine operation detecting device 24 to both the NC control unit control signal Cn and the main shaft start/ stop signal Cs for operation of the machine. And the signal change is transmitted in the form of the machine operation signal Ct to the NC command information production part TCH of the computer 18 for control. The present position display pulse signal Pp which is proportional to the extent of table shift due to the servo motor 20 is delivered from the NC control device 16. Then the present position counter 28 integrates the numbers of signals Pp and then transmits the present position information Pc to TCH. Based on these input signals, the TCH produces the teaching NC command information Nt and then decide according to the level of the teaching effective signal Ce whether the information Nt should be stored to the memory device 30. Then the device 16 decodes the information Nt after deletion out of the device 30 and through the command information deletion part DL, and then drives the motor 20. Thus an automatic reproduction is possible for the operation during the teaching.
