SPLINE INTERPOLATOR Russian patent published in 2004 - IPC

FIELD: numeric control systems. SUBSTANCE: spline interpolator incorporating new shaping control circuit in machining complex-shape parts has first through sixteenth differential digital analyzers and adder; integration function input of first differential digital analyzer also functions as input of spline interpolator; signal sum pulse arriving from eleventh, twelfth, and thirteenth differential digital analyzers is passed from output of adder built around follow-up integrator circuit in adding mode to input of sixteenth differential digital analyzer; outputs of fourth, seventh, and tenth differential digital analyzers function as first, second, and third outputs of spline interpolator, respectively. EFFECT: enlarged functional capabilities of numeric control systems. 1 cl, 2 dwg
