Abstract: A template for use with a jig having a workpiece positioning member. The template supports and guides a cutting tool used to cut joint members in two workpieces and comprises a support surface and at least one set of guides formed on the support surface for guiding the cutting tool. The support surface is movable with respect to the workpiece positioning member a predetermined distance between a first position to cut joint members in one workpiece and a second position to cut complementary joint members in another workpiece. This arrangement permits accurate routing of rounded or square finger joints or other types of uniform, spaced joints as determined by the template being used. Moving the template with respect to fixed workpiece positioning members means that no adjustment of the positioning members or workpieces is necessary between cutting of complementary joint members on separate workpieces which tends to result in more accurate cutting of the joints.

Abstract: A vacuum clamping system for trimming a flat or gently curved part from a sheet of material includes a template and a plurality of hold-down members, or pods, that sandwich the template between the pods and the workpiece. The template has a plurality of circular openings through its thickness. Each pod has an expandable bellows with an open suction end that extends downwardly through one of such openings, and comes into contact with and is closed by the workpiece. Subsequent evacuation of the bellows causes it to contract, thus pulling the workpiece tightly against one side of the template, and further pulling a clamping portion of the pod tightly down against the template's other side. This fixes the template in position between the pod and workpiece. Preferably, a number of pods are used in combinatiton with any given template to improve the clamping action.
