IPC: B23K26/14
Filed: 2002-03-05
Abstract: <P>PROBLEM TO BE SOLVED: To shorten a tact time through proper control of assist gas pressure and also to secure machining accuracy.  <P>SOLUTION: As a preparatory treatment before machining, while a plurality of different target pressure values are successively set, an applied voltage value for an electropneumatic regulator 20 is adjusted so that a detected pressure value of an assist gas near the nozzle port becomes the target pressure value. While the applied voltage is adjusted, the assist gas pressure is controlled by feeding back, the applied voltage value is stored at the time when the detected pressure value reaches the target pressure value. Then, corelations (corelation data) between the target pressure values and the applied voltage values are stored. At actual machining operation on a workpiece, an applied voltage value is determined from the corelation data stored in the preparatory treatment, the voltage value is quantitatively applied to the electropneumatic regulator 20.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for drawing a glass preform capable of performing such drawing that the external diameter after the drawing is made uniform.  <P>SOLUTION: The glass preform 11 is lowered by parting an upper chuck 12 clamping the upper part of the glass preform 11 and a lower chuck 12 clamping the lower part thereof relatively from each other. Namely, the descending speed of the lower chuck 12 is higher than the descending speed of the upper chuck 12 and therefore the glass preform 11 is drawn during descending. At this time, only the descending speed of the lower chuck 12 is made gradually higher in accordance with the amount of descending of the glass preform 11 and therefore the drawing speed is gradually increased and the glass preform 11 is eventually drawn to a smaller diameter. As a result, the external diameter which heretofore increases gradually toward the end of the drawing can be made uniform.  <P>COPYRIGHT: (C)2004,JPO
