    摘要: Numerical control for machine tools and the like of the genus described in McGee U.S. Pat. No. 3,656,124. Improvements are here described for digital computations and control which cause a tool or cutter to follow successive path segments programmed in workpiece edge coordinates, even though the servos operate to control the motion and positioning of the center of a cutter having a finite and unforeseeable radius. Additionally, automatic smooth transitions from segment to segment of the path are effected with a tangent fillet machined on the workpiece which has a radius equal either to that of the cutter or a value which is designated as a single numerical value in the program command data.

    摘要: A numerical path control system including a time shared digital computer generating for each of a plurality of axes regularly recurring numerical excursion commands. A two axis system is shown to be capable of deriving from a small number of data words successive straight line path or circular arc path command signals at a rate of 50 times a second and of converting these into intermediate or secondary command signals which are applied to the servos of the machine axes at a rate of 500 times a second.

    摘要: A two axis, digital, numerical control system for a turret lathe, using a common add-subtract unit which receives and sends information signals over a single pair of time-shared multiconductor trunk lines. A display device whereby information signaled during a selected time period and at either the inputs or the outputs of the adder may be viewed. For a more detailed abstract see Table of Contents.
