Provided is a system for setting a workpiece Cartesian coordinate system in a robot. In teaching the nose position (TCP) of a working member (tool) mounted on the hand of an articulated robot, the user moves the tool mounted on the hand to teach a reference point, any point on a predetermined axis and a third point defining a plane together with the other two points, whereupon a single coordinate system is specified by the position data indicative of these three points P1, P2, P3. A plurality of tool coordinate systems having a fixed relationship to the reference coordinate system of the robot can be set.

A data input/output unit which is equipped with a control device (1), a tape puncher (5), a tape reader (4) and a printer (6), and which is capable of operating even in response to a common from a host computer. The tape puncher is provided with a discriminating circuit for discriminating line feed code data, such that when line feed code data are sensed by the data discriminating circuit, line feed code data and carriage return code data are delivered to a punching section so that the line feed code and carriage return code may be punched consecutively. Further, the tape puncher is provided with a data discriminating circuit for discriminating consecutive code data indicative of a line feed code and carriage return code. When the consecutive code data are sensed by the data discriminating circuit, only the line feed code data are delivered to the punching section in order to punch the line feed code.

Disclosed is a data input/output unit which is equipped with a control device (1), a tape puncher (5), a tape reader (4) and a printer (6), and which is capable of operating even in response to a command from a host computer. The tape puncher (5) is provided with a counter (5h) for counting the number of print characters in one block, a parity designating circuit (5i) for determining a parity change indicated by a value counted by the counter, and a puncher control circuit (5c) capable of adding or erasing a parity code. The puncher control circuit (5c) performs an addition or erasure of a parity code in response to a parity signal from the parity designating circuit (5i).

A method and apparatus for creating numerical control data by entering coordinates which specify points on a drawing placed on a tablet. A minimum reading distance is preset at the time that coordinate values of points are to be entered from the tablet. This is followed by entering the coordinate values of prescribed points on the drawing by designating the points at random using a coordinate designating device. The coordinate values of the designated point are generated each time the coordinate designating device travels a distance equivalent to the minimum reading distance, or sampling pitch, as the device is moved continuously along a graphic appearing on the drawing. Then, numerical control data is created by using the generated coordinate values. Numerical control data approximating straight line segments can be readily created, even for curves other than straight lines and circular arcs, by setting the sampling pitch interval to a suitable value.

An area cutting method for cutting the interior of an area (AR) bounded by an external shape curve (OLC) including a number of straight lines (S1, S2, . . . S6) and a circular arc (A1). The method includes linearly approximating a circular arc portion (A1') of an offset curve (OFC) which is offset a predetermined amount from the external shape curve. Then an area bounded by the linearly approximated offset curve is divided into a plurality of convex polygons (PG1-PG3). The centroid (Wi) of each convex polygon and the mid-points (M1, M2) of boundary lines (B1, B2) of two mutually adjacent convex polygons are calculated, and a base line (BL) is generated by successively connecting each centroid and each mid-point. Straight lines (L1-L14) connecting the centroids (Wi) of the convex polygons and the apices (P1-P10) of the convex polygons, and straight lines (BL1-BL4) connecting the mid-points (M1, M2) and the two ends (P1, P4; P4, P7) of the boundary lines bisected by the mid-points are partitioned into a predetermined number of partitions. A tool is moved along plural closed paths (CPT1, CPT2, . . . ) obtained by connecting partitioning points (P.sub.a1, P.sub.a2, . . . P.sub.a18 ; P.sub.b1, P.sub.b2, . . . P.sub.b18), which correspond to the straight lines (L1-L14, BL1-BL4), in such a manner that the base line (BL) is enclosed. The tool is moved along the base line (BL) and along the offset curve (OFC).

A numerical control device 102, in which a processor 102a numerically controls a machine tool 103, is provided with an external storage unit 201 for storing machining data conforming to various shape patterns, input means 202, an editing processor 102c and an internal memory 102d, in order to implement a function for the creation of numerical control information. Machining data, corresponding to a part code entered from the input means 202, is read out of the external storage unit 201c. The editing processor 102c creates numerical control information, which is stored in the internal memory, from the machining data and, e.g., numerical values input from the input means 202.
摘要:
A graphic form or figure drawn on a drawing and larger than the read-out area of a tablet is divided into graphic patterns which are successively read by displacing the drawing. The extent to which the drawing is displaced is recognized, and graphic data read before and after the drawing is displaced is converted into data on one coordinate system and entered as inputs. For entering the graphic data, two points are specified on the drawing, and the coordinates of the specified points prior and subsequent to displacement of the drawing are read and stored in first through fourth registers. The stored coordinates and the coordinates of points on the figure are entered into a coordinate transformation unit which effects arithmetic operations of coordinate transformation.
摘要:
A tool compensation method for cutting a surface on a workpiece having a slanted surface. A radius at a final point is determined by a path computing unit using coordinates of the final cutting point and a tool height. Based on these values thus determined, coordinates of a final offset position, which is aligned with a tool center, is also computed. Corrective values in the directions of the X and Y axes are determined using the computed coordinates and coordinates of a starting offset position, to thereby correct the movement of the tool center.
