Abstract: A milling machine for a dental item comprises a six (6) axis motion system. A workpiece is fixed in space. Each of a pair of opposed tool spindles operates in 3 DOF, with an x-axis (laterally, left or right) being along an axis of each working tool, a rotational (theta (?)) axis (rotationally in or out), and a z-axis (up or down). On each respective side of the block, the x-axis rides on a ?-axis, and the ?-axis rides on the z-axis. Each z-axis supports a first carriage adapted to move up or down along the z-axis, and the first carriage supports a motor having a shaft. The shaft's rotational axis is the ?-axis. A second carriage is mounted on the shaft for rotation about the ?-axis.

Abstract: A system enables a consumer to generate a filtering program based on criteria set forth by a system operator during run time. During system operation, the operator selects appropriate filtering criteria from a display screen associated with a respective consumer. Each consumer implements filtering criteria in a filtering program that is registered with a distributor. The filtering program may include simple true or false tests, or more complex tests. The distributor compiles each filtering program during registration and thereafter dynamically loads the compiled program before executing filtering queries.

Abstract: A power tool (e.g. a laminate trimmer 10) includes an adjustable support for setting the position of the motor unit (16). The support includes a first collar element (24) secured to the motor and a support upright (14). A stud (32) threadedly secured to the collar is slidable in a slot (28) and co-operates with the slot (28) to maintain confronting surfaces (14a and 26a) of the elements in face to face engagement. The elements are thus constrained to slide only in a direction parallel to the upright (14). A clamping screw (36) threadedly engaged in the stud can be tightened to lock the adjustable support at a desired position. The arrangement provides high stability to permit adjustment of the motor position even when the motor is operating.

The machine includes mechanism which is manually actuated to effect controlled movement of the tool relative to either a rip fence which is selectively positioned on the table or a miter gauge slidable along a groove extending across the table. The rip fence or miter gauge is effective to prevent backlash and vibration of a work piece as one edge of the work piece is fed into cutting engagement with the router bit while the opposite edge of the work piece is in operative engagement with the fence or miter gauge.

Abstract: Apparatus for monitoring or tracking the angular position of a rotating camshaft during grinding or milling of cams on the camshaft. The cams may be milled, but in the apparatus shown, they are ground by abrasive belts which are guided by actuators driven by CNC controlled motors, to obtain the desired cam contours. Monitoring is carried out by a pick-up member engageable with a locating pin on the camshaft. The pick-up member has a slot for receiving the locating pin between a locator pad and a leaf spring. The leaf spring clamps the pin against the locator pad. The pick-up member will closely follow the rotation of the camshaft despite variations in pin size, and feed back the exact rotative position of the camshaft to the CNC controlled motors consistently and accurately.

Abstract: Contouring of a stack of one or more circuit boards is effected by first partially cutting the contour, leaving a portion of the contour long enough to ensure the rigidity of the circuit with respect to the board. The circuit is then clamped, while the remaining portion is cut without any discontinuity in the cutting. The machine comprises an operating head and a workpiece pressing pad which is operated for clamping the circuit during the cutting of the remaining portion of the contour. The pad is movable with respect to the head in a direction parallel to the uncut portion of the contour for displacement at least equal to the length of such portion. After the cut, as the head is raised, the pad is returned to rest position by the camming action of a roller against a sloping edge.

Abstract: A pair of routers are serially mounted on a pivotable support on a cutting table such that the routers may be adjusted in unison relative to the table. In addition the routers are adjustable relative to each other in a seesaw manner about a central cutting axis so as to maintain the axis. The apparatus and process of the present invention is particularly useful for making the male and female cuts of a dovetail joint in a single operation without requiring any adjustment of the routers relative to each other after the initial positioning. Depending on the cutting tool employed, dovetails, splines, rabbet cuts, mortise and tenon joints and countless other cuts may be made.
