摘要： 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.
摘要翻译：一种用于在其下侧上形成具有防滑板的工件或椅垫的装置和方法，以及具有楔形物的边缘周边区域以及用于修剪大致平面的工件的边缘的装置和方法。提供了可旋转的工作台来定位工件。路由器头包括可与工件的边缘接合的倾斜路由器刀片，以在其周围形成斜面斜坡边缘。模板定位在工件和工作台之间，并且路由器头部具有与模板的边缘接合并可移动的凸轮从动件，用于在工作台旋转期间沿着工件的边缘引导路由器刀片。冷却介质指向路由器刀片与工件边缘之间的接合区域。切割深度由安装在可与工件顶部接合的路由器头部的底部上的凸轮盘控制。
