Abstract: A method and an apparatus with rotating tool changer for automatically machining multiple sides of a workpiece which is trimmed and machined according to tags placed on the workpiece or preprogrammed sequence. A method that automatically selects and adjusts parametric computer machining code to machine various workpieces sizes. An apparatus comprising a handling and trimming station of parts to be machined, multiple optical, magnetic or radio-frequency identification (RFID) reading systems for processing labels or tags information for sequential workpieces machining steps, a multiple gantries computer numerical control (CNC) station for machining workpieces on various sides, multiple rotating tool changers for selecting tools used to machine workpieces, and a storage station that receives workpieces in sequential order when they have been processed.

Abstract: A key blank selector has a base, a template and a clamp. The base defines a chamber and a platform having a recess communicating with the chamber. The template is soft and pliable corresponds to and is detachably mounted in the recess of the platform. The clamp is detachably mounted around the platform of the base to hold and position the template in the recess and has an opening formed corresponding to the chamber of the base. A mother key is positioned perpendicularly on and force applied to pierce through the template and form a figure corresponding to a cross sectional profile of the mother key in the template; therefore, facilitating key blank selection and preventing misjudgment.

Abstract: A three dimensional tool guide includes first, second and third elongate guide arms mounted orthogonally and in series so as to provide X, Y and Z axes for the guide. The arms are interconnected by carriage means allowing free relative movement between adjacent arms in at least one direction and a balancing means to allow substantially unbiased vertical movement for the arm or arms. The first arm is adapted for mounting to a reference point and the third arm is adapted for holding and guiding the tool.

Abstract: The present invention is to provide a vending machine for engraved medals and a method of automatically engraving medals wherein an engraver is contained in the vending machine, and if a coin or a note is inserted into the vending machine and a starting button is pushed according to messages displayed on a monitor, a desired type of medal is selected and loaded on a bed of the engraver to be engraved according to a selected image, and the engraved medal is taken out outside the vending machine.

Abstract: A system for guiding a cutting tool utilizing a beam generator and a platten having a surface which is capable of presenting a pattern. The beam impinging on the platten is discernable. The beam generator is aligned with the cutting portion of the cutting tool such that the beam on the surface of the platten represents the position of the part of the cutting tool relative to a work piece. An operator may cut a pattern in the work piece by following the pattern on the platten with the beam image on the platten.

Abstract: An improved automatic shaping device wherein the shaping device includes a frame, a table mounted onto the frame, a movable template mounted onto the table, the table, a power-driven workpiece carrying member mounted to the table and a feed device for feeding the workpiece to a shaper mounted above the table wherein the shaper is provided with a shaper. The improvement includes a shaper mounted above the table wherein the shapper is provided with a vertically extending rotatable shaft having an upper end and a lower end wherein the upper end is in communication with a motorized drive and a cutter or shaper is attached to the lower end of the rotatable shaft.

Abstract: The engine disclosed herein comprises a number of pairs of pistons, the two pistons in each pair acting in unison and the number of pairs being arranged parallel to each other and said pistons also being positioned parallel to and in a circle around the mainshaft which has a cam lobe located at a convenient part of the mainshaft and encircling the mainshaft. The cam lobe has opposite surfaces which have rises and dips, or in other words, sinusoidal surfaces, and are in contact with pairs of bearings attached to connecting rods, these bearings being on opposite sides of the cam lobe and at one time being driven in one direction by one of the two pistons in each pair and then at another time in the opposite direction by the other piston in that pair, the two pistons of that pair being connected to each other by the same connecting rod carrying the bearings which press against the cam lobe.
