摘要： Trial machining is performed to determine the actual machining positions (P1, P2, ...) corresponding to the command positions (S1, S2, S3, ...) of each block of NC data. Point symmetry positions of the actual machining positions (P1, P2, ...) with respect to the command positions (S1, S2, S3, ...) of each block are calculated. Corrected NC data are generated as the command positions of each block whose point symmetry positions are corrected. The corrected NC data include a correction quantity for correcting the position error due to a delay of the servo system. Thus, performing the machining using the corrected NC data cancels this correction quantity with the follow-up delay due to the actual servo system delay, resulting in a more accurate machined shape.

摘要： The clamping speed and the injection start timing T are so adjusted that the sum SIGMA P of resin pressures acting on parting surfaces of a mold cavity does not exceed the clamping force F outputted at that point of time, and the clamping and the injection of the injection molding machine are simultaneously effected. The injection is started in the time from mold touching to completion of clamping, during which the clamping force F is weak. The gas in the mold cavity easily escapes therefrom even if any gas vent is not formed in the mold, and insufficient filling with resin and yellowing of resin are prevented. Further, since the clamping and injection are simultaneously effected, the total period of time required for clamping and injection is shortened by T' whereby the molding cycle is speeded up.
摘要翻译：夹紧速度和注射开始时间T被这样调节，使得作用在模具型腔的分型面上的树脂压力的总和SIGMA P不超过在该时间点输出的夹紧力F，并且夹紧和注射注塑机同时进行。注射从模具接触到夹紧完成的时间开始，在此期间夹紧力F较弱。即使在模具中没有形成任何排气口，模腔中的气体也很容易从中逸出，并且防止了填充不足和树脂变黄。此外，由于同时进行夹紧和注射，所以夹紧和注射所需的总时间缩短了T'，从而加快了成型周期。

摘要： A corresponding relationship between injection steps and injection velocities which are initially set in an injetion condition file is graphically represented on a display screen, and a starting point (P1) and a terminal point (P2) are designated on the graph to set a correcting section. Then a shape of a line segment connecting the starting point (P1) and terminal point (P2) to each other is selected out of a straight line and an arc for designation. In this manner, the section between the starting point (P1) and terminal point (P2) constitutes a new injection step. Futhermore, an injection velocity does not always have a constant value in the new injection step; it can be optionally set in a manner to linearly increase or decrease or change in an arc.

摘要： A method and an apparatus for making a zero adjustment of a pressure detector on an injection molding machine, in which the external load acting on the pressure detector is completely removed without disassembling its injection mechanism. While a screw (7) is driven in a low output condition, a forward limit position (Qf) and a backward limit position (Qb) are detected to determine the intermediate position (Pm) between them. The screw (7) is then moved to the intermediate position (Pm) to completely remove resin reaction acting directly on the screw (7). Reciprocating motion the amplitude of which decreases progressively is applied to the screw (7) to generate a backlash, i.e., an equal play between a ball nut (9) and a ball screw (8) in both forward and backward directions, and thus a zero adjustment of a load cell (10) is carried out under the state where the pressure acting on the load cell (10) is completely removed.

摘要： A numerical control method which shortens the cycle time of injection molding by opening the mold or by effecting ejection during metering, and an apparatus therefor. When the cooling period has passed or the opening of the mold is completed (S101) during metering, data for specifying the clamp axle or the eject axle is sent, the amount of moving of the axle is sent, and the moving speed and the moving direction, as well as a step feed instruction are sent (S104) from a programmable machine controller which sequentially controls the injection molding machine to the numerical controller which controls servo motors of each of the axles of the injection molding machine via a common RAM, pulses are distributed for the clamp axle or the eject axle based upon these data and pulses are distributed for the screw shaft alternatingly (S105, S100) by the numerical controller that works in response to the step feed instruction, the screw shaft and the clamp axle or the eject axle are driven simultaneously, and the mold is opened or ejection is effected during metering.

摘要： In an injection molding machine employing a servo motor as a source for driving the injection axle to drive the screw in the axial direction, a method is provided to smoothly shift the dwelling step to the metering/kneading step, in order to prevent the error register in the servo circuit from overflowing and to prevent the injection molding machine from coming into halt. When the dwelling step is finished, the error register is followed up (steps S6 to S8) such that the error quantity stored in the error register of the servo circuit that drives the servo motor for injection axle becomes zero. Then, a torque limit value to be applied to the servo motor is switched from a setpoint value for dwelling to a setpoint value for metering and kneading (step S11). The error register is then followed up again over a predetermined period of time from when the torque limit value is switched (step S13), and the step is shifted to the metering/kneading step (step S14).

摘要： An ejector mechanism is driven by a servo motor. An ejector pin of the ejector mechanism is caused to move so as to reach a predetermined protrusion limit position which is beyond a position where the removal of a molded piece from a cavity or a core is completed after positioning is confirmed and further caused to repeat several reciprocating movements with such a short amplitude that does not permit the ejector pin to withdraw beyond a position where the removal of a molded piece from the cavity or core is initiated, as well as to protrude and advance up to the protrusion limit position without confirming positioning.

摘要： A temperature control method for an injection molding machine, which constantly performs stable temperature control irrespective of the heat capacity of objects. The temperature of individual objects, such as a heating zone of an injection cylinder, an injection nozzle, a die, etc., are detected by temperature sensors G1 to Gn. A servo CPU (24) executes temperature feedback control so that the detected temperature coincides with a set temperature, and a current command value is determined. Furthermore, actual currents flowing through heaters H1 to Hn are detected, and currrent feedback control is executed so that the actual current coincides with the current command value obtained by temperature feedback control. In comparison with ON/OFF control, fluctuation of the currents flowing through the heaters H1 to Hn fluctuation of the temperatures of the temperature control objects become smaller, and temperature control can be made more stably.

摘要： A data display/input method of a CNC apparatus with which personal computers used as a relay means between the CNC apparatus and a host computer and a display means can be eliminated, and an FA network system can be constructed at a low cost. The display screen of the CNC apparatus is divided into a first display region and a second display region. The information inputted to the CNC apparatus from the host computer is displayed on the first display region. The information inputted to the CNC apparatus by an operator is displayed on the second display region. By switching the display attribute of the CNC apparatus side in accordance with the display attribute of the information inputted to the CNC apparatus by the host computer, the restriction of the data display on the CNC side is eliminated, so that text data and graphic data can be displayed.

摘要： In an injection molding machine employing a servo motor as a source for driving the injection axle to drive the screw in the axial direction, a suck-back method is provided to smoothly carry out suck-back, preventing the screw from proceeding in suck-back at the final step of metering and kneading. When the screw reaches the metering completion position, the screw is no more turned, and the error register is followed up (S1, S4, S5) such that the error quantity stored in the error register becomes zero. Then, a torque limit for imparting a preset back pressure for the servo motor is released (S8). The screw is then retreated using a servo motor by a predetermined sack-back amount (S11).
