Abstract
An edge finishing system for items such as polycarbonate panels. The system includes a multi-purpose edge-finishing tool which trims and smoothes the edges of a workpiece. The tool includes a contour cutter portion having a concave toroidal surface and a straight cutter portion having a cylindrical shape. A flute extends generally along with the tool's axis and defines a straight cutting edge and contour cutting edge. The system may include a fixture with vacuum cups nested within a platform so as to secure a contoured workpiece by static friction, permitting edges of the workpiece to be both trimmed and smoothly finished using a multi-purpose edge finishing tool, without marring or disfiguring the surface of the workpiece.
Claims25
An edge finishing system, comprising a multi-purpose edge-finishing tool for performing work on a workpiece, said tool comprising a cylindrical shank centered about an axis and insertable into a rotary power source, the tool including a contour cutter portion comprising a concave toroidal surface centered about the axis and interrupted by at least one contour cutting edge, the tool also including a straight cutter portion comprising a cylindrical surface centered about the axis and interrupted by at least one straight cutting edge.
An edge finishing system, comprising:
- a fixture for securing a workpiece;
- and
- a multi-purpose edge finishing tool for performing work on the workpiece secured by the fixture, said tool comprising a cylindrical shank centered about an axis and insertable into a rotary power source;
- the tool including a contour cutter portion comprising a concave toroidal surface centered about an axis and having a flute formed within the toroidal surface defining a contour cutting edge;
- the tool further including a straight cutter portion comprising a cylindrical surface centered about the axis, the flute extending through the cylindrical surface and defining a straight cutting edge;
- wherein the flute extends continuously between the contour cutter portion and the straight cutter portion.
