ABSTRACT:
A grinding method and tool support assembly which permits the cutting angle and relief area of a cutting tool to be ground, using only the outer peripheral surface of the grinding wheel in a conventional back and forth movement. The support assembly comprises an upright member resting on a surface, an elongated tool support having mounting means so constructed that, when secured to the vertical portion of the upright member, the tool support is displaced from the horizontal by the desired tool cutting edge angle, and a fastener for the tool support mounting means which permits it to be rotated on a horizontal axis. This permits the tool to be clamped in position so that the cutting edge and relief angle may be ground simultaneously. The grinding method includes the steps of inclining the tool from a supporting surface at the desired tool cutting angle, rotating it parallel to the supporting surface to obtain the relief angle, grinding one cutting edge and its relief angle, and if necessary reversing the tool and repeating the aforementioned steps to grind the other side of the cutting edge and its relief angle.
