PURPOSE:To minimize variances in measured value and to improve its yield by providing three cutting work stages and stopping feeding water while separating the cutting surface of a cutting machine from the work surface of a ceramic electronic component at specific distance every time one stage is finished. CONSTITUTION:The ceramic electronic component is cut up to a previously set place and then water feeding is stopped while the cutting surface of the cutting machine and the work surface of the ceramic electronic component are separated at specific distance; and characteristics of the worked ceramic electronic component are measured and the quantity y1 of cutting is calculated from the difference between the measured value and the 1st value which is stored and set previously. Then water begins to be fed again and a next cutting work stage is entered. In this stage, rough work is performed at a high speed determined by the performance of the cutting machine in the former half of the quantity y1 of cutting and precise work is performed at a low speed determined by required finish precision in the latter half. Then, the water feeding is stopped while the cutting surface of the cutting machine and the work surface of the ceramic electronic component are separated at specific distance, and characteristic are measured to calculate the quantity y2 of cutting from the difference from the 2nd value is which is stored and set previously, thereby performing the next cutting work stage similarly. |
