摘要： A method of control of NC machine tools of the type wherein all control data necessary for preparing machining data is inputted into a control device by key switches provided on an operating board. The data necessary for machining a workpiece stored in a microcomputer contained in the NC machine is reduced to the lowest minimum, while various data, such as the paths of movement of tools during rough machining, rough finish machining and finish machining, actually needed for machining the workpiece are successively computed on the basis of the data stored in said microcomputer in advance. Thus, data associated with a variety of workpieces can be processed with a minimum of memory capacity, and complicated shapes having concaves and convexes can accurately be machined in a simple operation.

摘要： A sewing control system for multiple-pattern sewing machine has a microprocessor coupled with a memory unit (ROM and/or RAM) and a switch matrix for designating a desired stitch pattern to achieve automatic sewing of a variety of stitch patterns. For stitch data formats processed by the microprocessor, there are used fixed-length or variable-length data including an operation code for designating data operations and a stitching frequency and a symbol code for designating the length and direction of a unit stitch. The memory unit stores a plurality of pattern data consisting of a number of stitch data each corresponding to the stitch pattern and a selection program for selecting the desired stitch pattern among these pattern data. When the desired pattern data designated by the switch matrix is selected among the pattern data in accordance with the selection program, A sewing machine provided with the control system performs sewing operation with the length and direction of each stitch specified as a vector in polar coordinates in accordance with the desired pattern data.

摘要： An electronic pattern stitching sewing machine has an arrangement for producing signals directing it to stitch a selectable number of patterns in series. These signals are then used to identify the last needle position coordinate of a preceding stitched pattern of the series and the initial needle position coordinate of the next-following pattern to be stitched in the series and, in dependence upon this, the most appropriate interconnecting pattern from a memorized group of such interconnected patterns is selected and stitched, so as to interconnect the preceding stitched pattern and the next-following pattern of the series.

摘要： A numerically controlled machine tool system which is responsive to a succession of stored data sequences to control the position of a cutting element with respect to a workpiece affixed to a workpiece positioning table. Each data sequence is associated with a point on a desired workpiece contour and includes data representative of a desired offset path which is parallel to and offset from a direct path of a selected type which intersects that point. During the machining mode of operation, the system determines a path segment for the cutting element to follow in association with a selected current sequence. For the current sequence, the system addresses only sequences in a contiguous group of sequences that includes the current sequence, and that relates to an identified portion of the desired workpiece contour. The system considers that contiguous group of sequences as forming an endless loop wherein the last sequence of the group precedes the first sequence of the group. For a current sequence, the system looks ahead to the next subsequent sequence and looks behind to the next previous sequence, determines offset paths associated with those sequences (in accordance with the offset data stored in association with the respective sequences), identifies the point of intersection of those offset paths, and then controls the cutting element to this intersection point. This operation is repeated in the machining mode of operation for each sequence in succession as the respective ones of the sequences become the current sequence, thereby permitting automatic cutting element path control together with desired selection offset values for use with individual machining operations.

摘要： In an NC tool machine having at least a linear control axis and a rotational control axis, a cutter compensation for compensating the difference between a programmed cutter radius and an actual cutter radius is automatically performed by calculating at least the locus of the actual cutter so that the programmed cutter touches the same position of a workpiece as the actual cutter does.

摘要： A digital to phase analog converter which accepts input digital data from a linear interpolator and produces a reference square wave signal for each machine tool and a command-position signal for each machine tool axis that is being controlled. Each command-position signal has a phase displacement from the reference signal that is related to the input digital data. The command-position signal is generated by adding the contents of a running counter to the contents of a phase control register. The high-order trigger of the adder produces the command-position signal.

摘要： A machine tool control system wherein command-position signals (such as square waves) are generated without the use of linear interpolation logic. A number representing a position in time equivalent to each rise or fall of the command-position square wave is generated and placed in a position register, which is compared with a running reference counter. An equal-compare signal reverses the level of a binary trigger and signals the apparatus to supply another number to the position register. The output of the binary trigger is used to generate the commandposition square wave.
