Abstract: A furniture design and manufacturing system utilizing initial selection of a design "vocabulary" of rectilinear cross-sectional shape "beams" that integrate structural and aesthetic considerations, and utilizing panels coordinated in thickness to be received in dados and rabbets in the beams. Beam cross sections generally have a predetermined incremental size difference, or multiple of the incremental size difference, so that beams inter-fit and cooperate with panels and other beams in a graduated manner permitting a sort of "nesting" when beams, or panels and beams, are used together. This facilitates joinery in furniture using such components because, among other reasons, mortises tend to fall in thicker components than those having tenons. Production of beam stock and, if desired, panel production precedes identification of a furniture item to be produced, facilitating economies in production.

Abstract: A method of creating a decorative inlaid floor includes the first step of providing a cutting implement, such as a router, which is operable to machine an inlay recess in a finished wood floor. The next step is to position the router over a section of the floor and move the router in a particular manner so that the desired inlay recesses are machined. The operating and movement step requires that the decorative pattern be predetermined and a control program or NC tape be generated so as to control the drive motors which are associated with each of four slide assemblies. Once the desired inlay recesses are machined into the main floor, the control program is modified by scaling it up to a larger size and is then utilized on a panel of a contrasting material. A typical example would be to select a contrasting wood for the inlay elements. The reprogrammed router is then located over the second material panel and operated so as to machine a larger inlay recess in that second material panel.
