Problems solved by technology

One of the problems encountered in the prior art in forming joints is the requirement for clamping mortises together to permit bonding agents used to permanently secure the workpieces together to set.
Still an additional problem encountered in the prior art is the necessity to provide labor for applying such clamps and subsequently removing them when the bonding agent has cured.
Such an operation is undesirable in the sense that it adds additional labor to the construction of the final product, and may detract from the appearance of the product, weaken the completed joint or possibly even result in damaging the material beyond salvage.

Embodiment Construction

[0014]Generally, in the cabinet making trade, machining operations required for making mortise and tenon joints for joining panels together are performed on a CNC router. The various components comprising the main body of a kitchen cabinet, as an example, are generally machined on a flatbed CNC router, from full sized sheets of panel stock. The process also may be carried out using a handheld portable router, or by using ordinary cabinetmakers' hand tools, although the latter is considered more of an art than a craft.

[0015]Referring to FIG. 3 of the drawings, in a typical manufacturing environment utilizing a CNC machine 301, components are manufactured by first loading a tool-path program into the machine control 302. Material in the form of full sized sheet stock is then placed upon worktable 302 of the CNC machine. The tool-path program through the computer component of the machine control 302 then guides the tool 304 through multiple program cut paths, producing components that ...

Abstract

A method of forming a joint between first and second workpieces generally consisting of forming a recess in one of such workpieces, provided with at least one side wall having a serrated cross-sectional configuration with inwardly projecting, distortable segments; providing a portion in the other of such workpieces, insertable into such recess, having a cross-sectional configuration sufficient to engage and distort such segments as such portion is inserted into such recess; and inserting such portion of the other workpiece into such recess, causing the segments to distort and thus provide an interference fit between such workpieces.

Description

[0001]This invention relates to an method of forming a joint between a pair of workpieces, and more particularly to a such a method that does not require the use of clamping devices in positioning and holding such workpieces together, allowing a bonding agent applied to the joint to set. Such invention further contemplates a product formed through the use of such method and a tool functional to configure such workpieces to facilitate the practice of such method.BACKGROUND OF THE INVENTION[0002]In the manufacture of furniture and other similar products, it is a common practice to utilize mortise and tenon type joints to interconnect various workpieces used to construct a product. The mortise and tenon joint consists of a socket formed in a first workpiece, and a protrusion formed on a second workpiece adapted to be inserted and snuggly fit into the socket or mortise of the first workpiece. In the cabinetmaking industry, the terms mortise and tenon often are used to describe a broad r...
