PLAYBACK TYPE NC MACHINE TOOL
Document Type and Number:
Japanese Patent JPS5622107
Kind Code:
A
Abstract:
PURPOSE:To secure an automatic correction even for the tool having a different diameter from that during the teach-in, by calculating the moving locus of the envelope surface of the tool's contour based on the machine operation signal during the teach-in and then storing the moving locus. CONSTITUTION:The teach-in machine operation signals Mtc are transmitted successively to computer 16 during the teach-in. In computer 16 NC command information Nc which gives a direct command to the movement of the tool's center is produced based on signal Mtc. In the case of the tool diameter correction mode, information Nc is converted into tool diameter correction type NC command information No to be stored in memory device 22. In case playback command information Np means command information No during the playback, the tool's center route displaced by the extent equivalent to the tool's diameter supplied from keyboard 24 is directed to machine tool 12. In such way, such working is given to the working object 26 so that the tool's moving route directed by information Np may form a contour.
