    摘要： A machine tool has a carriage (28), has a workpiece carriage (28) for carrying a workpiece (32) from which material is removed by a tool (54) carried by a tool carriage (48). A two-axis scale (86, 88) is attached to one of the carriages, and cooperates with a reading head (96, 98) attached to the other carriage. The output from the reading head is processed by signalling processing means to provide an indication of the position and/or movement of the carriages relative to each other and for generating positional data about one or both of the carriages to assist in controlling their movement in order to perform a machine operation. By directly measuring the relative positions of the two carriages, problems arising from, for example, distortions of the machine frame on which the carriages are mounted are at least mitigated. A preferred embodiment of the machine incorporates a second reading head attached to one carriage and incorporating the scale on another carriage so that the outputs from the two reading heads can be used to determine whether there has been any relative angular displacement of the paths followed by the carriages. There is also provided a method of determining the linear movement of one of the carriages relative to the other, and the machining process achieved using the machine tool.

    摘要： An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction through an automatic joystick. The sewing machine head is mounted on a cross beam which is aligned at the approximate center point of the metal frame on which the fabric is stretched. The needle of the sewing machine head can stitch a pattern into any location in the fabric and the metal frame is moved in any direction relative to the fixed sewing machine head in order to bring the desired stitch location on the fabric into alignment with the sewing machine head. The precise location of the sewing machine needle and fabric is illuminated and a color video camera which is mounted on the cross beam holding the sewing machine head is also focused on this location. The color video camera is connected to a television monitor so that a visual image of the sewing machine needle and fabric as a stitch is being made can be delivered to the monitor. A machine operator can control the movement of the metal frame through positioning by a remote joystick and can see the stitch being made by viewing the monitor. The apparatus also includes a reprogrammable function integrated into the system wherein the operator first manually traces the desired pattern using the existing joystick system. At the end of this step, the traced pattern is stored into the memory of a computer as a digitalized image of the pattern. The computer can then cause the pattern to be subsequently repeated at any multiplicity of desired locations.

    摘要： In an encoder output method and a servo motor encoder according to the present invention, the number of signal lines is reduced by using common signal lines and common output terminals. In the encoder output method and the servo motor encoder, incremental signals (A, B, Z) and servo motor magnetic pole position detection signals (UE, VE, WE) are switchably output by a common driver (2) through a pair of timers and a multiplexer (30), or a pair of timers and two line drivers (60, 70) are selectively active or inactive, and common signal lines are used, thereby reducing the number of signal lines.

    摘要： A method and apparatus are described for measuring the velocity, whether rotary or reciprocating, of a servo shaft driven by a motor, without employing a tachometer. From the movement of the shaft is produced a pair of signals in quadrature, with transitions expressible in Gray code for one cycle as 00, 01, 11, 10 and then back to 00. Meanwhile, a clock provides a large number of evenly spaced counts per selected quadrature transitions. The number of counts between two selected quadrature transitions is read and the total number of quadrature transitions between the selected transitions is divided by the total number of counts during the same time.
