Abstract
PURPOSE:To attain a work shape of high precision by detecting the change of quadrant in circular interpolation and performing compensation at the time of detection to prevent the deviation of the work shape from a program shape. CONSTITUTION:A start angle thetas and an end angle thetae are obtained from a command of circular interpolation, and an angle theta of arc opening is calculated by thetas-thetae, and DELTAtheta is so calculated that the peripheral speed is a designated value. Xn and Yn of a movement destination Pn are obtained until nDELTAtheta=theta is true and interpolation is terminated. It is discriminated whether interpolation passes the angle, where the quadrant is changed, or not in accordance with thetas-nDELTAtheta and thetas-(n+1)DELTAtheta. An extent of movement corresponding to the quantity of a dead zone is added to Xn if it passes 0 deg. or 180 deg., and the extent of movement corresponding to the quantity of the dead zone is added to Yn if it passes 90 deg. or 270 deg., thereby performing correction to obtain axial power.
