Abstract:
A coping apparatus that performs a cope cut of varying diameters and angles on varying sizes, diameters, and types of materials without having to change the diameter of the cutting tool. The apparatus comprises a table with a clamp, a cylindrical housing with an aperture pivotally mounted to the table, a motor, a tool, and a yoke assembly. The yoke assembly is rotatably received within the housing and comprises a upper disc with a channel, a lower disc with a channel, a upper arm, a lower arm, a connector, and a handle. The arms are received in the channels of the upper and lower discs and moveable in a direction radial to the rotation of the discs. The motor is mounted to the lower arm and turns a spindle and the tool. Upon manipulation of the handle, the tool is plunged into the material to make the cut.

Abstract:
A circuit board router (10) and method thereof. De-paneling of printed circuit boards (62) off a panel 860) is efficiently increased by a router (40) which is positioned at a location above the panel (60). A fixture positions the panel 860) below the router (40) on a base (16). A controller (64) activates a first drive mechanism (20), a second drive mechanism (26), and a third drive mechanism (32) to guide an X-arm (18), a Y-arm (24) and a Z-arm (10), respectively. The router (40), located on the Z-arm (30), moves downward to engage a router bit (42) to the panel (60) to depanel the printed circuit board (62) from the panel. A fixture chip (72), which has a preprogrammed pattern of the panel (60), is embedded inside the fixture (58). A radio frequency transmitter (80) transmits the pattern to a radio frequency receiver (82) that relays the pattern to the controller (64).
Abstract:
An improved electronic controller for the motor of a high-speed spindle attachment used in conjunction with a cnc milling machine. The controller comprises preventative circuitry that protects the spindle assembly of the attachment from overload accruing as a result of relatively moderate increases in torque demand during use. The controller senses the power level being used by the motor while it causes high-speed spindle rotation, and when it identifies a power consumption rate by the spindle that exceeds the operator pre-set maximum level determined to be safe for avoiding catastrophic spindle damage, the electronic controller sends a signal back to the computer controlling the axes of the cnc milling machine that is sufficient to slow, pause, and/or stop the feed-rate.
Abstract:
A machine tool (1) for the at least partial machining, contour-dependent cutting or milling of a component from a plate-shaped workpiece (2), for example a wood plate, is provided, and includes a suction device used as a clamping device for engaging on the back side or lower side of the workpiece (2). A second clamping device including at least one hold-down device (6) that is used to apply pressure to the side of the workpiece (2) facing away from the suction device (3) and (4) is provided. The hold-down device (6) has on its contact region that applies pressure to the workpiece (2) at least one or two spaced-apart pressure rollers (7), and is displaceable under pressure relative to the workpiece (2) transversely to the axis of the pressure roller(s) (7). The displacement is synchronous with a tool (8) used for the machining of workpiece (2), which tool can preferably be situated between the two spaced-apart pressure rollers (7).
Abstract:
The system constructed according to the present invention operates by properly positioning a base compact disc (CD) onto a cutting table and then cutting the CD to a preprogrammed shape. Base CDs are stacked on an elevator system. The CDs include one side on which data is recorded, and another side on which the CD label is printed. A robotic arm with a vacuum gripper then picks-up a CD from the stack and moves the CD to a cutting table. While the arm moves the CD, a machine vision system takes a picture of the CD label and compares the picture to an image of the label stored in data. An image mapping program then determines the rotational orientation of the CD by comparing the picture and data image. Once the orientation of the disc is known, the robot arm rotates the disc a calculated amount so that it can then be placed on the cutting table in a proper normalized orientation. The CD is held in place on the cutting table by a vacuum chucking system. A routing tool then plunges through the CD and cuts an edge of a desired shape. Once cutting is complete, a second robotic arm with vacuum grippers picks up the shaped CD and associated single scrap piece. The shaped CD portion is placed on a vertical mandrel and the scrap piece is discarded in a bulk bin. The completed system is intended to have four (4) independent machine vision systems and routing stations so that four CDs can be shaped at the same time.

Abstract:
Described is a draw-in nipple for fastening a palette on a machine tool, with the draw-in nipple for fastening of the palette being received by a rapid-action clamping system, with the draw-in nipple being attached afflicted with clearance on the palette and through application of a tension force in its longitudinal direction away from the palette being lockable free of clearance. The draw-in nipple is herein preferably received in a resilient element which upon exertion of a tension force becomes deformed and locked through the draw-in nipple.
Abstract:
The invention relates to a process of butt-welding together sheet metal plates, in particular those having different sheet metal thicknesses, by means of an edge preparation to the extent that the edges of the sheet metal plates are milled in a sheet metal stack (5). For this purpose, the appropriate apparatus has a supporting and clamping means (1, 2, 3, 9, 10).
Abstract:
A roller hold down device for removable work table which has a pair of rollers which extend transversely across the workpiece mounted on the movable table so as to hold it down and with a pair of cam roller members mounted on either side of the movable table and formed with cam portions so as to engage the rollers at the end of travel so as to force the rollers up away from the workpiece and also so as to prevent the rollers from falling off of the end of the workpiece. The rollers are controlled by hydraulic cylinders which can be actuated to automatically move them to the down position and also to move them to the up position.
