A "memory" mirror system having a mirror 19 mounted within convex-shaped mirror movement boundaries, two constant speed motors 16,18 each controlling an axis of mirror movement, position feedback signals 26,28 from each motor, push button inputs 12 and an electronic controller 10, is provided with automatic mirror repositioning that drives the mirror from a start position to a "memory" position in minimum time without colliding with any mirror movement boundaries by turning ON the motor, in the direction of the target, whose movement axis is the greatest distance from the target and turning ON the other motor, in the direction of the target, if the direction toward the target is also toward the center of the mirror movement pattern (i.e., away from the nearest boundary).

A tool move control method is disclosed. It comprises the steps of setting an interference area for an object which should not be interfered with a tool when a tool rapid move is instructed by a start point and a terminal point for the tool movement, setting an entry prohibit quadrant for prohibiting the tool entry and two or more of quadrants for permitting a move of the tool in the interference area, and controlling a move mode of the tool according to quadrants belonging to the start point and the terminal point in such a manner as to avoid the entry prohibit quadrant. A tool move control apparatus is also disclosed.

A shuttle transfer assembly (10) is able to accurately position a workarm (12) in two axes (X, Y) to a selected coordinate position. The assembly (10) include two position controllers (74, 76) each operating along a single axis for positioning the workarm (12) to the coordinate position. A central controller (86) functions to control the sequencing of the separate position controllers (74, 76). Coarse and fine sensors (62-68) are provided to allow feedback of position to the position controllers (74, 76). The coarse sensor (62, 64) operates for general positioning as an encoder on the servo drive motor. The fine sensors (66, 68) extend from the workarm (12) to produce the final, high resolution positioning.

A computer aided design and manufacturing system for decorating glass and other objects using graphic arts extrusion (GAME). Adhesive material combined with pigments adding false metal coloring and thicotropic properties for application upon glass and other objects is performed to provide false metal bead lines simulating stained glass and camed glass panels. A conventional x-y plot table is equipped with a specially designed nozzle for extruding materials and a computer is provided for controlling the plot table. The computer allows for flexibility in altering designs and enables operators or artisans to develop intricate detailed designs. Multi-dimensional ridges formed on decorative objects are made in the form of patterns which are filled in with colored varnishes or lacquers to fake a stained glass appearance.

A numerical control apparatus for independently controlling the rotational velocity of a plurality of spindles. One or more spindles and one spindle rotational velocity are designated by NC data outputted by an NC data generating unit (1), the data in memories (3a-3n) corresponding to spindles designated by switching unit (2) is updated by the designated spindle rotational velocity, and motors (6a-6n) of corresponding spindles are controlled to rotate at the spindle rotational velocities stored in the memories (3a-3n).
摘要:
A mirror control system for electrically powered and positioned mirrors (FIG. 1) of the "memory" type for, for example, moving an automotive side view mirror from its current position to a desired "memory" position, and a special algorithm therefor (FIG. 2), which initially moves the mirror toward the final, desired position at a forty-five (45.degree.) degree angle to the vertical and horizontal axes (NE, NW, SW or SE; FIG. 6), for a mirror whose two directional motors have equal speeds (X=Y). If no obstruction (e.g., the mirror's edge) is encountered (FIG. 3), the mirror is moved by both motors until either the vertical or horizontal axis of the final position is encountered, at which axis intersection point the mirror is moved by only the appropriate one of the motors until the final point along the remaining axis is reached; this is the "normal" mode of the algorithm. However, if an obstruction is encountered (left side of FIG. 2; FIGS. 4 and 5), the mirror is moved at a 45.degree. degree angle toward its center point (or a "safe" central position) until its reaches either the center point's vertical (FIG. 4) or horizontal (FIG. 5) axis, and then a single motor is used until the center point is reached. THe analogous "normal" mode is then used to move the mirror to its final position. If the speeds of the horizontal axis and vertical axis direction motors are not equal (X.noteq.Y, respectively), then the angle for the initial movement(s) is "arc tangent (Y.div.X)".

There are provided method and apparatus for controlling a robot, in which when the robot is continuously controlled in different directions such that from the movement in the horizontal direction to the movement in the vertical direction, the movements in the horizontal and vertical directions from a predetermined position are executed in parallel during the movement in the horizontal direction. In the method, target movement positions in the horizontal and vertical directions are input, a first distance which is necessary to move the robot in only the vertical direction is input, and the predetermined position is determined on the basis of the target movement positions in the horizontal and vertical directions and the first distance. The movements in the horizontal and vertical directions include the equal acceleration motion and the equal deceleration motion. With this method, the operator can easily perform the programming and teaching of the robot such that the robot can reach a desired final target position while avoiding obstacles without colliding therewith in the shortest time.

A memory mirror system having a mirror 19 mounted within concave-shaped mirror movement boundaries, two constant speed motors 16, 18 each controlling an axis of mirror movement, position feedback signals 26,28 from each motor, push button inputs 12 and an electronic controller 10, is provided with automatic mirror repositioning that drives the mirror from a start position to a memory position in minimum time without colliding with any mirror movement boundaries by driving the mirror position toward the target along the axis farthest from the target and driving the mirror toward the origin along the other axis until the mirror position is within a predetermined safe region along that axis or the current position is 45 degrees from the target, then driving the mirror in the direction of the target along an axis for which the distance to the target is not less than the distance to the target along the other axis or in which the direction toward the target is also toward the origin.
摘要:
A programmable controller for closed-loop positioning control has a main processor unit, and an I/O interface rack in which a master I/O positioning module and three satellite I/O modules are mounted and connected to servomechanisms to control motion along three axes of a controlled machine. Move data is transmitted from the main processor unit to the master I/O positioning module in data blocks, with the number of transmissions varying, depending upon a mode of axis coupling that is used in controlling the particular machine. The master I/O positioning module converts move data from a user program format to a binary format and transfers it to the satellite I/O modules, each of which performs closed-loop positioning control of a respective axis of motion. The processor on each satellite I/O module also determines a position prior to the end of each move to apply a user-programmed deceleration when needed to blend moves having different velocities.
摘要:
An electro-mechanical control system for controlling all of the movements of one or more slides on a single workhead grinding machine. A programmable controller is interfaced with a digital to analog converter or feed control which in turn controls a drive motor that is directly connected to a screw actuator means that directly controls the movements and positions of a slide. The positioning accuracy of the control system is derived from the accuracy of the electronic control components and the stability of the machine. The control system can control the operative movements of each slide in a compound slide assembly, simultaneously or independently, for a part of a grinding machine cycle. The compound slide assembly may alternatively carry a rotating grinding wheel or a workhead that is reciprocated at high speed for a grinding operation on a workpiece.
