The angle that specifies the rotation of a machine tool about the y axis.

BOBILLIER'S LAW

The law that, in general plane rigid motion, when a and b are the respective centers of curvature of points A and B, the angle between Aa and the tangent to the centrode of rotation (pole tangent) and the angle between Bb and a line from the centrode to the intersection of AB and ab (collineation axis) are equal and opposite.

ARBOR

  1. A cylindrical device positioned between the spindle and outer bearing of a milling machine and designed to hold a milling cutter. 2. A shaft or spindle used to hold a revolving cutting tool or the work to be cut.

MILLING CUTTER

[DESENG] Arotarytool-steelcutting tool with peripheral teeth, used in a milling machine to remove material from the workpiece through the relative motion of workpiece and cutter.

AXIAL RUNOUT

The total amount, along the axis of rotation, by which the rotation of a cutting tool deviates from a plane.

GEAR CUTTER

A machine or tool for cutting teeth in a gear.

CLEARANCE ANGLE

The angle between a plane containing the end surface of a cutting tool and a plane passing through the cutting edge in the direction of cutting motion.

VSA

GEAR GENERATING

A method of gear cutting in which the tooth is produced by the conjugate or total cutting action of the tool plus the rotation of the workpiece.
