Abstract
A fixture for holding a cutter for a vertical turret lathe may comprise a block with a blind hole. A cutter with an indenter on its distal end may be secured within the hole such that a portion of the indenter comprises a positive rake angle.A method for testing cutters may comprise securing a cutter on a fixture of a vertical turret lathe which has a cutting material positioned adjacent the cutter. The cutting material may be rotated around a rotational axis at a constant rotational velocity. The fixture may be urged laterally such that the cutter progressively moves towards a periphery of the cutting material. The rotational velocity may be decreased as the cutter moves laterally to maintain a relative constant linear velocity between the cutting material and the cutter.
