Abstract

PURPOSE:To realize the interpolation along a spline curve which is formed in an on-line method by commanding the shift value set per unit time on a set spline curve as an interpolation vector. CONSTITUTION:A tape reader 2 reads the data on the tool shift out of a command tape 1 and decides by operating the coefficient of a spline curve via a pre-processing means 3 based on an instructed point train P in case the data includes a G code of an interpolation command. A pulse distributor 6 changes the parameter (t) of a function which prescribes the decided spline curve and performs the spline interpolation with the shift value per pulse distribution cycle in the tangential direction. The shift command undergone the spline interpolation is outputted to a servo control circuit 7 as a command pulse of each axis of a tool. Then a servo motor 8 is driven for shift of the tool.
