ABSTRACT:
An improved sine bar apparatus for the precise measurement of angles for machining operation. The sine bar apparatus comprises a flat, rectangular base which has an upper and a lower surface with four sides. A collet adapter extends from one side of the base at right angles thereto in a plane which is parallel to the upper surface of the base and there is at least one slot extending transversely of one side of the base. A reference bar is attached to one of the other sides of the base and has a support surface which extends above the upper surface of the base. An elongated, generally rectangular sine bar, which has a reference surface extending along one side, is pivotally connected to the base and is supported on the upper surface of the base. The sine bar is pivotally connected at a point intermediate its ends, though the transverse slot adjacent the side of which the reference bar is attached, and has one of its ends in contact with the support surface of the reference bar. The other end of the sine bar is separated from the support surface of the reference bar by means of a plurality of gauges or gauge blocks which are precisely machined to cause the reference surface of the sine bar to form a predetermined angle with the longitudinal axis of the collet adapter. The reference bar and the sine bar can be attached to either of the three sides of the base to provide a variation in the angles measured.
