摘要： The system described is particularly useful for tracing a twolobed epitrochoid contour in order to produce this complex shaped housing for the Wankel rotary engine. The system generates the precise tool-center path in the form of incremental motion command pulses which are supplied to X-axis and Y-axis positioning systems to effect the relative displacement of a tracing tool (e.g. a cutter or grinding wheel) with respect to an object (e.g. the workpiece) to trace on the latter the two-lobed epitrochoid surface, and at the commanded feedrate velocity. The system described is a hard-wired one arranged to perform all the operations in parallel to achieve a very high output rate. The required calculations are performed by approximation techniques involving only simple addition, subtraction or numerical comparison, but no trigonometric operations.

摘要： System for control of tool drive with respect to at least X and Y axes to trace a first path segment and to approach a second path segment (e.g., for tool offset, or to trace an inscribed curve tangent to the two path segments), by steps comprising storage of data descriptive of X and Y positions corresponding to current X and Y tool positions and of a first function the value of which is dependent upon the perpendicular distance from the X and Y positions to the second path segment, updating of the stored data upon advance of the drive during the tracing of the first path segment, and interruption of the tracing of the first path segment when the function assumes a predetermined value.

摘要： A new and improved numerical control system is described which has an offset value count-in control means for adjusting the current value of an offset being used by the numerical control system to a new value by counting into the system a count indicative of the magnitude and polarity of the difference between the existing offset value currently employed by the numerical control system and the desired new offset value. The offset value count-in control means comprises reversible counter means for storing data indicative of a current offset value being employed by the numerical control system. A comparator is provided having a first input coupled to a value indicating output from the reversible counter and having a second input supplied with data indicative of a new or input offset value. The comparator serves to compare the existing offset values set into the reversible counter to the new or input offset value and to derive a count-adjusting output signal indicative of the magnitude and polarity of any difference. Means are provided for feeding the count-adjusting output signal derived from the comparator back to a count-adjusting input to the reversible counter for adjusting the count contained in the reversible counter to a value corresponding to the new or input offset value. Means are also provided for supplying this count-adjusting output signal from the comparator to the numerical control system for adjusting the offset value being employed by the numerical control system to the new or input offset value.

摘要： A system in which the radius of a tool is compensated for in the three-dimensional machining of a workpiece, wherein a tool is offset from a commanded tool path by a distance commensurate with the tool radius. Machining is performed by commanding the contour of the workpiece as a tool path in a prescribed plane sectioning the workpiece, providing the value of the tool radius and the angle of inclination of a machined surface of the workpiece, computing a first tool offset quantity in the prescribed plane and a second tool offset quantity in a direction at right angles to the prescribed plane, based on the radius of the tool and the angle of inclination, compensating for the radius of the tool in the prescribed plane based on the first tool offset quantity, correcting the position of the tool in a direction at right angles to the prescribed plane based on the second tool offset quantity, and machining the workpiece in three dimensions based on the compensated tool radius in the prescribed plane and the corrected tool position in the direction at right angles to the prescribed plane.
