Abstract
An apparatus and method for forming a workpiece or chair mat with cleats on the underside thereof, and with a marginal peripheral area void of cleats, and for trimming the edge of a generally planar workpiece. A rotatable work table is provided for positioning the workpiece. A router head includes an inclined router blade engageable with the edge of the workpiece to form a beveled ramp edge thereabout. A template is positioned between the workpiece and the work table, and the router head has a cam follower engageable with and movable along the edge of the template for guiding the router blade along the edge of the workpiece during rotation of the work table. A cooling medium is directed toward the area of engagement between the router blade and the edge of the workpiece. The depth of cut is controlled by a cam disk mounted on the bottom of the router head engageable with the top of the workpiece.
