Information : Computerized Dot Peen Marking Machine
The computerized dot peen marking machine provides Bell Helicopter Textron, Inc. (BHTI) with a consistent means of legibly marking a wide variety of material. It is not dependent on the individual skills of the person marking the part.
The Marktronic machine is built by the Wetzel Tool Company of Bloomfield, Connecticut. The system is a computer controlled machine tool capable of marking a line of text, straight or circular, with up to 24 characters. It consists of an IBM PC with a minimum 256K RAM, a controller, and a marking head. Text is entered via the keyboard and a wide variety of sizes and depths are available. Each character is formed by a series of dots that are arranged in a 5" x 7" matrix. The characters are indented by means of a carbide tipped stylus driven by a solenoid actuated punch. Editing of all text is accomplished by adding, inserting, or deleting characters without having to retype the whole line prior to marking the part.
The text layout can consist of one to eight lines. The system has the ability to store up to 1,440 layouts in six groups of up to 240. Back-ups of all layouts may be made and stored for future use.
