Numerical positional control
Abstract
Abstract A numerical positioning control embodying a digital computer circuit means which can be influenced in sets by a program, this digital computer circuit means serving to generate a feed control signal for a second displaceable unit. The aforementioned computer circuit means determines during the duration of each program set, the path slope in the form of a ratio between both mentioned signals. Further, the digital computer circuit means embodies switching means which can be influenced in sets by the program and which, for the purpose of describing curved path sections, brings about during the duration of the set, automatic continuous changes of the programmed starting values of the path slope.
