10.4. Formation of the scanning file for CNC
To form the scanning file for the machine CNC system, it is necessary to set
scanning parameters according to par. 10.3.4, press the "Form file for CNC" button in
the section "B" of the program working window, and define the place in the PC memory
where the control file must be written. The output text file contains control G-codes for
correct movements of the machine.
10.5. Scanning of the item
To perform scanning it is necessary to:
• use control program for CNC to open the file formed by the "Ashera"
program according to par. 10.4;
• position the machine movement system to a point from which scanning
must be started;
• press the "Start session" button in the section "C" of the program
working window;
• start the machine to execute the program.
The task execution time depends on the size of the scanning region, speed and
step values with which the carriage moves along the X and Y axes
After the machine has executed the program, it is necessary to switch the scan-
ning mode off by releasing the "Start session" button.
10.6. Formation of the result file
The result of scanning is displayed in the section "E". Control of the item image
in this section is possible with the help of the mouse pointer:
- dragging of the mouse with the left key pressed - rotation of the item;
- dragging of the mouse with the right key pressed - movement of the item;
- scrolling with the mouse - zoom-in and zoom-out of the item (scaling).
To obtain the result file, it is sufficient to press the "Form result file" button, se-
lect the file type (STL/DXF/TXT) in the emerging window, enter the file name, select file
folder for saving and press the "Save" button.
Note: when working with 64-bit PC, the program offers to perform simplification (STL-
file size reduction) before saving results, which is important for scanning large-size ob-
jects or for fine-pitch scanning.
In the window write percents of file reducing and save file.
To make changes in the region already scanned (discretization interval along the
X or Y axis, length and width of the region), it is necessary to enter new values and
press the "Recalculate region" button (section "C"). To return to the initial view of the
model (if filters were used and limits along Z were set), it is sufficient to switch off the fil-
ters and press the "Recalculate region" button.
