Printed circuit board working machine

摘要

A printed circuit board working machine includes a working table on which a printed circuit board substrate is positioned and fixed, a spindle which is disposed above the working table to be movable horizontally and vertically and to which a predetermined cutting tool is detachably mounted, a controlling unit for controlling the movement of the spindle in accordance with a predetermined cutting data and a data processing unit operatively connected to the controlling unit. The data processing unit includes a data input circuit into which a circuit pattern data is inputted, a contour data preparation circuit for preparing a contour data of a circuit pattern to be prepared from the circuit pattern data from the data input circuit, a hatching data preparation circuit for preparing a hatching data to carry out a hatching operation with a predetermined width in a predetermined direction for working a residual portion of a circuit pattern to be prepared in accordance with the contour data from the contour data preparation circuit, and a cut data preparation circuit for preparing a cut data by continuously connecting adjoining hatching data at end portions thereof in accordance with the hatching data from the hatching data preparation circuit and transmitting the this prepared cut data to the controlling unit.
