Automated drawing

The mentioned system can be modified, so a ruler is moved over a sheet of paper instead of moving a table under the cutter. Such a system is suitable for drawing complex curves based on simple instructions issued to the computer.

Such systems are used to draw the side sections of cams, and to draw large calibrations for sheet metal work, and in the manufacture of circuits

(The computer prepares new design drawings)

Microelectronic circuits that have been widely used in recent years in various electronic devices, including computers. These circuits are manufactured by spreading certain materials in small pieces of silicon through masks formed according to the required circuit, then by chemical tapping through other similar masks. Since these masks are very small, they are drawn by magnifying them greatly and then photographically reduced to the required small size. The computer seeks the optimal design for these circuits and draws the required masks.

Automatic manufacturing

The required parts can be manufactured automatically, and the computer prepares the necessary designs and controls the machine tools that produce the parts. The relevant part is drawn on a television screen using a light ruler connected to the computer. The computer scans the entire surface of the screen using an electron beam. If the light ruler is in a specific position on the screen

(Drawing by computer)
(Several machine units can be controlled in serial operations using magnetic tapes prepared by the computer for a single design).

It receives a light flash when the electron beam passes through it, and sends an interruption signal to the computer, so the computer recognizes the position of the ruler on the screen. This process is repeated as the ruler is moved on the screen, and in the end the drawing of the required part is completed. The dimensions in this drawing are determined by instructions to the computer entered via a normal touch panel. The computer interprets the required drawing correctly and prepares the pulse sequences necessary to produce the part automatically.

These pulses are recorded on magnetic tapes that are later transferred to the machine tool control devices. A single computer system may prepare designs under which several machine tools are programmed, saving a lot of time in the manual calculation of all the dimensions required in the various operations.
