US 2015/0127135 A1 · METHODS FOR MACHINING SHARP INTERNAL POCKET CORNERS WITH ROTATING CUTTING TOOLS

Abstract

Methods of machining a housing of a portable computing device are provided. A cutting tool may be moved perpendicularly to a rotational axis during each rotation thereof to machine a substrate and define pockets and holes including substantially non-rounded corners. In this regard, the cutting tool may be translated perpendicularly to the rotational axis during each rotation of the cutting tool to define a non-rounded cutting profile, where desired. Translation movement perpendicular to the rotational axis may be provided by a controller actively controlling actuators of a computer numerical control (CNC) mill or other rotary machine.

Dependent claims

A method for machining a substantially square hole into a substrate, the method comprising:

rotating a cutting tool about an axis in a first direction, the cutting tool defining a plurality of flutes that extend to a fixed radial distance with respect to the axis when rotating thereabout;
translating the cutting tool along a cutting path in a second direction opposite the first direction, the cutting path arranged substantially perpendicular to the axis, wherein a translational position of the cutting tool is synchronized with each of a plurality of rotations of the cutting tool;
and
wherein the plurality of flutes include a first flute defining a first cutting edge of the cutting tool.
