Abstract
The present invention relates to a honing method and apparatus which provides greater control over the edge shape, as well as reductions in the effort required to hone multiple edges on workpieces. The invention accomplishes these improvements by controlling the speed of the abrasive wheel, as well as the orientation and position of the workpiece prior to and/or while it is in contact with the abrasive brush. This provides for greater control over the hone shape, hone size, and hone distribution along all the cutting edges of the tool.
Claims12
A process for honing at least one edge on a workpiece comprising the steps of:
- placing a workpiece in a fixture;
- rotating an abrasive brush about an axis of rotation, the abrasive brush including a plurality of abrasive bristles which define a volume;
- positioning the workpiece edge relative to the axis of rotation of the abrasive brush such that the workpiece edge to be honed is substantially parallel to the axis of rotation;
- positioning the workpiece edge to be honed at a circumferential location relative to the axis of rotation of the abrasive brush, the circumferential position being selected to provide a desired hone shape;
- positioning the workpiece edge to be honed at a radial distance from the axis of rotation of the abrasive brush, the distance being less than the radial length of the bristles of the abrasive brush;
- and
- translating the workpiece along a path substantially parallel to the axis of rotation of the abrasive brush such that the workpiece edge passes through at least a portion of the volume of the abrasive brush.
A process for honing at least one edge on a workpiece comprising the steps of:
- placing a workpiece in a fixture;
- rotating an abrasive brush about a rotational axis, the abrasive brush including a plurality of abrasive bristles which define a volume;
- adjusting the position of the workpiece edge relative to the axis of rotation of the abrasive brush such that at least a portion of the workpiece edge to be honed is substantially parallel to the axis of rotation of the abrasive brush and in the proper position to be honed;
- translating the workpiece along a path substantially parallel to the axis of rotation of the abrasive brush such that the workpiece edge passes through at least a portion of the volume of the abrasive brush.
