Abstract
A method of modifying a workpiece such as a geared member includes grinding the workpiece with a rotating grinding wheel, and superimposing a primary motion of the axis of rotation of the grinding wheel with a secondary, oscillatory motion of the axis of rotation. The primary motion is oriented perpendicular to the axis of rotation. A motorized apparatus for modifying a workpiece includes a workpiece holding device, a grinding wheel which rotates about a first axis, and the first axis rotating about a second axis, wherein the workpiece holding device and the grinding wheel are moved toward each other in a direction of feed normal to the first axis and permitting a radial face of the grinding wheel to grind against the workpiece via intermittent contact.
Claims24
A method of modifying a workpiece comprising:
- grinding the workpiece via a plurality of passes with a rotating grinding wheel, including moving an axis of rotation of the grinding wheel back and forth relative to the workpiece;
- and
- while grinding the workpiece, moving the axis of rotation of the grinding wheel relative to the workpiece in a primary motion along a path oriented perpendicular to the axis, wherein moving the axis of rotation includes superimposing onto the primary motion a secondary, oscillatory motion of the axis relative to the workpiece.
A method of grinding a profiled form member comprising:
- grinding at least one groove in the member via a plurality of passes with a rotating grinding wheel, including moving an axis of rotation of the grinding wheel back and forth relative to the member;
- and
- moving the axis of rotation of the grinding wheel relative to the member in a feed direction oriented perpendicular to the axis, including moving the axis via an oscillatory motion thereof relative to the member.
A motorized apparatus for grinding a workpiece comprising:
- a workpiece holding device which holds thereon a workpiece to be modified;
- a grinding wheel which rotates about a first axis, the grinding wheel having a radial face and two opposed axial faces, each of the axial faces having a circumferential edge, each circumferential edge being joined to the other by the radial face;
- the first axis rotating about a second axis that is generally parallel to and offset from the first axis, defining an oscillatory motion of the first axis relative to the workpiece;
- and
- wherein the workpiece holding device and the grinding wheel are moved together in a direction of feed, defining a primary motion of the first axis upon which the oscillatory motion is superimposed, that is normal to the first axis permitting the radial face to grind against the workpiece.
