Abstract: The majority of computer controlled machining centers lack any provision for loading individual parts onto the machine for future machining operations and lack the ability to remove these same parts after machining operations commence. A mechanism which fits into the spindle of existing machine tools and harnesses the energy to the rotating spindle to grip parts facilitates automated machine tool operation without making significant changes to the architecture of the machine tool or requiring the addition of an external part loading device. Parts awaiting machining operations can be arranged on the table of the machine tool, stacked on the machine table, fed via a chute to the machine tool, or fed using some other traditional method of parts feeding. To further facilitate automated machine operations, dedicated tool holders for taping and drilling operations may be equipped with reservoirs containing cutting fluid which is dispensed when the spindle is rotated sufficiently fast before being stopped.

Abstract: A dadoing system that can be set up to cut multiple dados in a workpiece. The dadoing system uses a sliding channel clamp to keep the workpiece from moving in a transverse direction, while the dados are being cut into the workpiece. The sliding guide rails are used to put downward pressure on a workpiece while guiding a router across the workpiece during the dadoing process. Once the system is set up to cut the dados in the desired locations on the workpiece, the sliding guide rail stops can be secured into place. The stops will insure that the sliding guide rails are set up in the same place thus allowing multiple workpieces to have matching dados that line up properly during assembly.

Abstract: Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

Abstract: A device for holding an object, and an assembly for holding and rotating an object. The device includes a base, a series of posts, each of which is equidistant from a center point of reference and further pivotably holds a follower rotationally linked to all other followers. Each follower has a gripping portion dimensioned to hold an object. An actuator serves to displace the followers radially about the post holding it creating a motion that causes the gripping portions to move either towards or away from the center reference point, dependent upon the displacement of the actuator. As all followers are rotationally linked, each follower of the device rotates to a substantially equal degree.
