Abstract
An electro-mechanical gaging apparatus and method for measuring the diameter of gundrill bits that have been pointed and the cylindrical surface areas relieved to leave only the margin and the wear pad on the circumference. A V-block of about 100 degrees is used in combination with a dual segmented clamp and a gage probe for generating electrical signals which provide the necessary inputs for trigonometric calculation, e.g. by an electrical microprocessor, thereby providing the desired diameter measurement.
