ABSTRACT:
A method and device for measuring the shape and dimensions of a workpiece which is to be cut by a sawing machine. The method includes detecting the width of the workpiece, detecting the contact angle or contact position when the saw blade contacts the workpiece, detecting the presence or absence of a workpiece vertical side surface, judging whether the cross-sectional shape of the workpiece is round or square from data including the width of the workpiece, the contact angle or contact position, and the presence or absence of a workpiece vertical side, and displaying and calculating the dimensions of the workpiece. The device includes a width detector for the detecting the width of the workpiece, a contact angle detector for detecting the contact angle or contact position when the saw blade contacts the workpiece, and a vertical surface detector for detecting the presence or absence of a workpiece vertical side surface. Also included is calculation apparatus for judging whether the cross sectional shape of a workpiece is round or square from the data including the width of the workpiece, the contact angle or contact position, and the presence or absence of a vertical side surface, as well as apparatus for displaying the shape and dimensions of a workpiece.
