Title:

METHOD FOR GENERATING REFERENCE AMOUNT FOR POSITIONING CONTROL CIRCUIT IN NC/MACHINE

Document Type and Number:

Japanese Patent JP3871278

Kind Code:

B2

Abstract:

PURPOSE: To provide an improved reference amount generating method for a control circuit in a numerically controlled machine by deriving a position target value from the sequence of appropriately weighted preceding bus target values.
CONSTITUTION: Reference amounts to an interpolator are a speed V from a data set preparing element. An interpolated sequence signal V (K) is supplied to a sequence from a primary dead time element 43. A proportional element 44 is arranged at each dead time element 43, and the output signal of the proportional element 44 is accumulated by an adding part 45. The output signal of the adding part 45 is supplied to an adding part 46. The output signal of an integrator 41 is supplied through an (n) dimensional dead time element 42 to the adding part 46. A corrected position target value LΛ (K) is outputted from the output side of the adding part 46. The formation of the position target value LΛ (K) is based on a path speed value V(K-i) of (n-1) for the preceding sampling point of time and a value L(K-n) of the preceding position.
