Abstract
A jig for adapting a cutting machine to cut a work piece along a radius. The jig includes a base for mounting the jig to the cutting machine. A bridge is pivotally mounted to the base. The bridge is further configured to receive the work piece. A slide is disposed beneath the bridge, where the slide is configured to selectively engage the bridge at a desired position along a length of the bridge. The slide mounts to the table at a variable position along a length of the table, and the slide is further configured to move the bridge relative to the base in a generally arcuate manner.

A jig for adapting a cutting machine to cut a work piece along a radius, the jig comprising:
- a base configured to be mounted to a table of the cutting machine, the base having a base longitudinal axis extending along a base distal end and a base proximal end;
- a pivot defining a pivot point disposed adjacent the base distal end;
- a bridge having a bridge distal end and a bridge proximal end, the bridge pivotally mounted to the base adjacent the base distal end via the pivot, and the bridge configured to receive the work piece in one of a plurality of secured positions between the bridge distal end and the bridge proximal end, and
- a slide configured to engage the bridge between the bridge proximal end and the pivot point of the pivot, the slide extending along a slide longitudinal axis extending along a direction substantially perpendicular to the base longitudinal axis, and the slide including a guide configured to move in the direction substantially perpendicular to the base longitudinal axis such that the movement of the guide in the direction substantially perpendicular to the base longitudinal axis causes the bridge and corresponding work piece secured to the bridge to move in a generally arcuate manner.
A method for milling a work piece on a cutting machine having a table and a cutting tool, the method comprising the steps of:
- mounting a jig to the table of the cutting machine, the jig including:
- a base having a longitudinal axis extending along a base distal end and a base proximal end,
- a pivot defining a pivot point disposed adjacent the base distal end;
- a bridge having a bridge distal end and a bridge proximal end, the bridge pivotally mounted to the base adjacent the base distal end via the pivot, and the bridge configured to receive the work piece in one of a plurality of secured positions between the bridge distal end and the bridge proximal end, and
- a slide configured to engage the bridge between the bridge proximal end and the pivot point of the pivot, the slide extending along a slide longitudinal axis extending along a direction substantially perpendicular to the base longitudinal axis, and the slide having a guide configured to move in the direction substantially perpendicular to the base longitudinal axis of the base such that the movement of the guide in the direction substantially perpendicular to the base longitudinal axis causes the bridge and corresponding work piece secured to the bridge to move in a generally arcuate manner;
- securing the work piece between the bridge distal end and the bridge proximal end in one of the plurality of secured positions;
- engaging the cutting tool of the cutting machine with the work piece;
- and
- moving the guide of the slide such that the movement of the guide in the direction substantially perpendicular to the base longitudinal axis moves the bridge and corresponding work piece secured to the bridge in a generally arcuate manner for producing a radius cut in the work piece.
A jig for adapting a cutting machine having a cutting tool in a fixed position to cut a work piece along a radius, the jig comprising:
- a base configured to be removably mounted to a table of the cutting machine, the base having a base longitudinal axis extending along a base distal end and a base proximal end;
- a bridge pivotally mounted to the base at a pivot point and having a bridge distal end and a bridge proximal end, the bridge configured to receive the work piece in one of a plurality of secured positions between the bridge distal end and the bridge proximal end for adjustably positioning the work piece adjacent to the fixed position of the cutting tool;
- and
- a slide configured to engage the bridge between the bridge proximal end and the pivot point of the bridge, the slide extending along a slide longitudinal axis extending along a direction substantially perpendicular to the base longitudinal axis, and the slide including a guide configured to move in the direction substantially perpendicular to the base longitudinal axis such that the movement of the guide in the direction substantially perpendicular to the base longitudinal axis causes the bridge and corresponding work piece secured to the bridge to move in a generally arcuate manner in relation to the fixed position of the cutting tool of the cutting machine.
