NEUMERICAL CONTROL MACHINE TOOL

摘要

PURPOSE:To improve the operationability thus to shorten the working time and to improve the working accuracy by correcting the position on the basis of a position setting error of working machine and correcting the profile error only on the basis of such error as to be manipulated through correction control. CONSTITUTION:A profile detecting means 11 where the position in the direction of core height contacting with a work 3 fixed to a chuck 2 is same with that of a tool 6 is secured to the tool table 5. Said table 5 is secured to the upper face of XY table 4 to be moved respectively in Z, X directions through table drive motors 7a, 7b. The output from a profile detecting means 11 of working machine body 1 having aforementioned arrangement is fed through an amplifier 12 and A/D converter 13 to data input section 85 of numerical controller 8 then to an arithmetic processing section 82. While said section 82 is provided with data from an external memory 14 pre-stored with predetermined numerical data through control section 86 and data from control command tape 9 through read- out section 81 to feed the results through control section 83 and amplifying sections 84a-84c to required drive motors 7a-7c thus to perform highly accurate profiling.
