The invention relates to mechanical engineering and can be used in the raster data can be printed signs with changeable width of the stroke path, for example the texts of the Arabic alphabet.

Source information is not known a method of applying information with a variable width of the stroke path that is required for the application of the Arabic script, but it is known device [1], equipped with a marking insert, which is made in the form of a raster grid, consisting of isolated conductive elements associated with the programming device, the feeding of the individual electrical signals in accordance with the configuration of marked character.

However, this device does not allow you to put signs with changeable width of the stroke path.

The invention is aimed at obtaining a font with variable width of the stroke path.

This is achieved by working on the raster elements of the tool serves the voltage from the power source, the value of which for each work item is chosen in proportion to the ratio of the desired stroke width on the workpiece to the width of the stroke to raster tool.

It is also known device [2] for the bitmap marking, in which the conductive elements are assembled in blocks, forming horizontal and vertical (tilt) the series in the form synthesisof is of marked character.

The disadvantage of this device is the inability to obtain signs with changeable width of the stroke path.

To implement the method a device (1)comprising a raster grid 9, consisting of isolated conductive and non-working 1 12 elements associated with the programming device, which is equipped with a sensor width of the stroke path 5 connected with the analog system 4 identify elements of marks in the raster, while at work and non-work elements of the raster offset set to a value close to polprasert between the largest and smallest width of the path opposite of stroke damage information, and the cross-section of business and non-business elements of the raster is not more than the minimum width of the stroke path on the workpiece.

The invention is illustrated by figure 1 and 2. Figure 1 shows the diagram of a method and device in figure 2 is the device for its implementation. At work items 1 (1), required for the formation applied to the preparation of the index, the current supplied from the current source 2 through the switch 3, the input current on all working (under current) elements 1. In the analog system 4 the width of the stroke path by the information in place for the broadening of h2(figure 2) is compared and is the ratio of h2./h1.From the system 4, the signal value is supplied to the sensor width is by the path of the bar 5 specific work item 1, where is the voltage regulator 6. When the voltage rises around a work item (for example 1 in figure 1) occurs, the electric field boundaries 7, reaching the border 8 of the extended part of the stroke path, opposite the considered element (for example 1). Extreme in the raster 9 working elements 10 is connected to the extreme element 10 has been shifted relative to the border 8 by a value not less than h (figure 2). The diameter of all raster elements 9 is not more than the minimum width of the contour of the fixed portion 11 of the bar. In raster 9 may include not involved in the marking of outside elements (such as 12 in figure 1).

The method is as follows. According to a drawing by the data set size and location of plots contour strokes with a width different from the width of the main circuit of the sign. Data is fed into the analog system 4, which are identified in accordance with the specified information with the non-working elements 1 in the raster 9 and for each work item is the ratio of the width of the circuits 8 and 11 (2) (h2./h1.This ratio may be greater or less than unity. Data value received in the voltage regulator 6, where for each work item 9 raster is formed by the voltage applied to the switch 3 with the identification of a work item from the analog system 4 through Yes the chick width of the stroke path 5. In the analog system 4 by the well-known relations (see, for example, Vpostav, Gpomerantz, Subcatego Electrochemical marking details. M: mechanical engineering, 1983, 72 S. [3], 13, and 21, calculate the voltage for the circuit is caused to mark the outer boundaries 7 (figure 1), which coincides with the boundaries of the circuit 11 or 8 (figure 2). The increase in the contour of the sign to the border 7 allows you to find the ultimate border of the anodic dissolution of the workpiece about the extreme portion of the path 8 of the working element 10. Analog system 4 selects a work item near the extreme section of the sign, corrects for him at offset h the value supplied from the controller 6 voltage from the power source 2.

An example of the method: you want to put information in Arabic alphabet letter "F"with a local thickening of 1.2, thickness of lines of the main circuit, of a width of 0.28 mm Depth marks on the workpiece is not less than 0,005 mm By known [3] to the recommendations of the select voltage marking 4, and 13 in [3] we find the voltage at the working element of the contour of the sign in place thickening (4.8 In). The data entered in the analog system 4 and the sensor bar width 5. The described process can be carried out automatically, if you know the dimensions of the contour of marks applied to the item. The voltage regulator 6 according to the signal from an analog system 4 pod is t on the selected system 4 work item (or items) in the zone of expansion of the sign of the increased voltage, forming the "broadening" of the path to the border 7. After a definite time to 0.72 seconds (set by a timer, not shown in the illustrations,a mark is formed and the process is terminated. Measurement of the sign showed that its dimensions match the drawing (the amount of the thickening 0,34±5%), and the depth 0,006-0,007 mm Thus, the present invention allows to expand the technological capabilities of raster marking on signs with changeable width of the stroke path, for example, for application information, the Arabic alphabet.
