Abstract

After an emergency braking operation is released in the case of a numerically controlled machine, the path calculated by the interpolator continues to be traveled, so that braking takes place on this path in the interpolation clock cycle. To determine the braking-interpolation points (P.sub.iB), a factor k is defined for each axle, which factor fulfills the condition of at least one axle being decelerated by a maximum amount and the remaining axles being decelerated more slowly.
