Numerical control for machine tools or robots

摘要

In normal numerical controls, a predetermined input resolution (EF) has the effect that the maximum speed with which, for example, transport axles can be driven, is limited. Therefore, in the invention, for the speed guiding stage (GF) of an interpolation stage (I) of the control, an interpolation resolution (IF) matched to the respective speed (F) to be driven is introduced, the interpolation resolution (IF) being many times more coarse than the input resolution (EF). By these means, the driving speed (F) can be increased without reducing the contour truth of the desired movement track. <IMAGE>
