Abstract

PURPOSE:To prevent the collision of a tool without performing the special regulation even if the tool or the work is changed, by performing the figure processing of the image in the proximity of a cutting edge through a TV camera secured to an edge table. CONSTITUTION:A work 2 is fixed to a check 1 of a main shaft table 7. A TV camera 10 is fixed to a cutting edge table on a reciprocating table 8 carried by a screw 31 to provide the image signal VS in the proximity of a cutting tool 6 to a figure processor 20. The command from a tape 32 is provided through a command level register to a function generator 34, then the command level P from said function generator 34 is compared with the current level A from a position detector 35 to drive a servo motor 30 through a servo motor drive circuit 38. When the work, tail stock, etc. is caught on the screen of the TV camera at the quick carry of the reciprocating table, the screen area will vary to provide the stop signal DT from the figure processor 20 to the servo motor 38 thus to stop the servo motor quickly.
