  • Patent number: 5035598
    Abstract: An optimum molding condition setting system for an injection molding machine comprises a molten material flow analysis component for analyzing resin flow, resin cooling and the structure/stength of molded products by using a designed mold model and also comprises an analysis result evaluation component for determining an initial molding condition and its permissible range in accordance with the analysis results. The initial molding condition is set into the injection molding machine and a test shot is carried out in order to check for a deficiency of a molded product. If a deficiency of the molded product is detected, a data of the deficiency is entered into a molding defect elimination component. After performing a convenient data processing based on the entered data, a cause of the molding defect can be inferred and a measure for the cause can be obtained with high efficiency and accuracy.

  • Patent number: 4583159
    Abstract: A numerical controlled machine tool apparatus capable of providing intermediate measurement (in process measurement) during the carrying out of a machining process on a workpiece. A spindle of the apparatus, usually used for mounting a machining tool, is also capable of mounting a measuring tool which generates a contact signal when the measuring tool on the spindle is brought into contact with the workpiece. A measuring control unit including a memory is capable of compensating for any deviation that may exist between a center axis line of the measuring tool and the center axis line of the spindle, thereby making the apparatus capable of carrying out accurate measurements and adjusting a machining process based on the result of such an accurate measurement.

  • Patent number: 4484118
    Abstract: A numerical controlled machine tool provides a detector which produces a detecting signal when it is brought into contact or out of contact with a workpiece for measuring same. A driving device relatively moves the detector with respect to the workpiece, and a position detecting means for detecting the position of the detector. The numerical control device provides a signal corresponding to an amount by which the detector is moved with respect to the workpiece and causes the driving device to stop in accordance with the detecting signal. In operation, the numerical control device detects when the detector contacts with the workpiece while moving at a first speed, and applies a stop signal which is produced from a detecting signal given by the detector. The detector is then moved in a direction away from the workpiece at a second speed by a distance which is either larger or smaller than the distance by which the detector moved and stopped after the first detecting signal was produced.
