Abstract:

A rotary precision circle cutter device, wherein the material to be cut is placed on a table which is rotatably mounted on a base, and cut by a cutting implement attached to an articulated cutter arm assembly mounted on the base. The articulated cutter arm assembly movably extends over the rotatable table in a direction generally perpendicular to the axis of rotation of the table, with the cutting implement being securable in any of a plurality of positions along the radius of the table by movement of the articulated cutting arm. In a preferred embodiment, the rotatable table is mounted on a swing arm to allow the rotatable table to move with respect to the base, and detachably mounted template cams are employed, which rotate conjointly with the table and a template-cam engaging bearing, such that the axis of rotation of the table can be displaced with respect to the cutter arm to trace a shape congruent with the shape of the template can during conjoint rotation of the table and template cam.
