摘要:
To provide a motor driving apparatus capable of obtaining high detection resolution irrespective of whether a frequency of a signal from a detector is high or low. A motor driving apparatus for driving a motor includes an amplifier circuit for receiving a signal from a detector for outputting information including a position and a speed of the motor as the signal, and amplifying the received signal with a set amplification factor, a frequency detecting part for detecting a frequency of the signal, and an amplification factor setting part for changing setting of the amplification factor of the amplifier circuit according to the frequency detected by the frequency detecting part.

A workpiece registration unit provides dimension signals representative of the diameter of a cylindrical workpiece while a plunge cut therein is made by a grinding wheel of a grinding machine. The dimension signals are provided in response to a workpiece error signal generated by a gage having probes in contact with the workpiece. During the plunge cut, the dimension signals are utilized to control movement of a wheel slide of the grinding machine which is connected to the grinding wheel. The movement causes a responsive change in wheel slide signals provided by a wheel slide registration unit. After substantially completing the plunge cut, the wheel slide signals are altered to correspond to the dimension signals of the workpiece registration unit. The probes are retracted from the workpiece and a portion thereof having a keyway therein is plunge cut with the (previously) altered wheel slide signals being utilized to control the movement.

A dimension comparator for machine tools is disclosed wherein a first comparator compares a theoretical numerical dimension with an actual dimension as determined by a position measurer. After it is determined that the actual dimension is greater or less than the theoretical dimension, a second comparator compares the actual dimension to a numerical value representing the theoretical dimension plus or minus the numerical value of an aiming interval. This representative numerical value is determined by an adder controlled by the output of the first comparator. In an alternative embodiment, means are provided for controlling the adder to add predetermined increments to the theoretical dimension for comparison in the second comparator.

A display control apparatus operable to display an operation of a robot comprising: an obtaining unit configured to obtain measurement information of a processing target that includes at least one of the robot and a target that the robot operates; an emphasizing unit configured to generate emphasized display information that emphasizes a feature of a portion of the processing target, based on the measurement information; a composition unit configured to generate composite display information in which the emphasized display information and non-emphasized display information other than the emphasized display information are composed; and an output unit configured to output the composite display information to a display unit.
摘要:
In a wire-cut discharge machine, a workpiece fixedly mounted on a movable table is returned from the present position to a machining start position so that auxiliary objects, such as clasps for holding the workpiece, and structural objects, such as the nozzle of the wire-cut discharge device, do not interfere with each other. Relative coordinate values between the machining start position and the present position are calculated and the calculated results are displayed on a display device. The workpiece is moved in an X-direction and is then moved in a Y-direction toward the machining start position based on moving data corresponding to the calculated results.

In an improved digital readout for machine tools, an apparatus is provided which automatically offsets the digital position display by the radius of the cutting tool. A machinist is thereby enabled to work more rapidly and with reduced chance of making errors.

A PANEL SAW FOR CUTTING PANELS INTO SMALLER PIECES HAS A FIRST CARRIAGE FOR MOVING THE PANELS IN STEPS IN ONE DIRECTION TO BE SAWED IN A DIRECTION AT RIGHT ANGLES THERETO AND A SECOND CARRIAGE FOR MOVING THE SAWED PIECES IN STEPS IN THE SECOND DIRECTION TO BE SAWED IN THE FIRST DIRECTION INTO STILL SMALLER PIECES AND IS CONTROLLED BY A DIGITAL COMMAND SEQUENCER INCLUDING MEMORY AND LOGIC UNITS THROUGH WHICH A DESIRED SEQUENCE OF FEED MOVEMENTS AND SAWING ACTIONS MAY BE COMMANDED AUTOMATICALLY IN ACCORDANCE WITH A PROGRAM INTRODUCED MANUALLY OR FROM AN EXTERNAL SOURCE DIRECTLY INTO THE MEMORY OF THE SEQUENCER. SELECTOR MEANS ENABLE THE SEQUENCER TO BE OPER-
ATED IN SEVERAL MODES FOR EITHER INSERTING DATA TO PRODUCE A PARTICULAR PROGRAM, OR FOR UTILIZING AN INSERTING PROGRAM TO CARRY OUT A PARTICULAR SEQUENCE OF CUTS ON PANELS INTRODUCED INTO THE MACHINE. A MANUAL KEYBOARD AND DIGITAL DISPLAY PANELS ALLOW TH OPERATOR TO GENERATE DIMENSIONAL DATA AND TO INSERT IT INTO THE CONTROLLER''S MEMORY DIRECTLY FOR SUBSEQUENT UTILIZATION TO COMMAND A SEQUENCE OF SAWING AND FEEDING OPERATIONS IN ACCORDANCE WITH THE PARTICULAR PROGRAM SELECTED.
摘要:
An on-line data processing machine controls the operation of one or more machine tools. A general purpose communications link allows each machine tool and/or the operator therefore to communicate with the data processing machine and either change the operations which the machine tool would otherwise perform under control of an existing stored program, or add new or partly new operations, which if desired can thereafter immediately be performed by the machine tool.
