PURPOSE:To correct the work of the depth of a hole by moving a table manually along a tool spindle and at right angles to the slanting tool spindle when a shaft rotates and the tool spindle slants. CONSTITUTION:When a tool 12 is moved manually in an X''-axis direction at right angles to the tool spindle to perform work, a movement selection switch SX is turned on and an operator rotates the handle of a manual pulse generator 103 to generate a specific number of pulses Hp. When the pulses Hp are generated, the distributing circuit in a manual pulse distributing circuit 104 performs arithmetic. Namely, the addition of a register and an accumulator is performed every time a pulse Hp is generated and the addition result is stored in the accumulator repeatedly to generate a specific number of overflow pulses by respective accumulators by the generation of N pulses Hp. Manual pulses XHp, YHp, and ZHp are generated by this distribution arithmetic and supplied to servo circuits 108-110 through adders 105-107 to drive motors 113-115. |
