Basics
Technology blocks, specify in which way the machining should take
place, e.g. centering first, and then drilling, the contour blocks describe
the contour you want to machine and the positioning blocks determine
the positions for the drilling or milling machining (e.g. position the drill-
holes in a full circle on the front surface).
A program chain is closed when a technology element is completed with a
position element. Otherwise an error message lets you know if one of the
parts is missing.
2.2.4 End of program
End of the program signals to the machine that the machining of the
workpiece has ended. In addition, you can specify the number of
workpieces that you would like to machine.
This program block is marked by the icon
of Program" with a letter "N", indicating the number of workpieces you
want to machine:
2.2.5 G code blocks
In the work plan G code program blocks can also be inserted, besides the
ShopTurn program blocks.
For this, you must place the cursor somewhere in the editor window
where you want to insert the G code block.
Pressing the yellow "INSERT"-key on the keyboard, opens a new orange
command line, marked with the letter
can enter G code commands.
From a G code line you can not switch to a parameter mask window.
2.3 Navigation in the editor window
For a fast and comfortable navigation within a sequential program and the
parameter masks you can use the blue cursor keys.
With the blue "cursor-up" key on the keyboard you
can navigate upwards in the program editor and the
parameter masks.
With the blue "cursor-down"-key on the keyboard
you can navigate downwards in the program editor
and the parameter masks.
The arrow symbol (extend-symbol), on the right
side of the program block line in the editor window,
indicates that you can access the parameter mask
by pressing the "cursor-to-the-right" key.
The "cursor-to-the-right" key opens the parameter
mask of the corresponding program block.
The "cursor-to-the-left" key closes the parameter
mask of the corresponding program block and
brings you back to the work plan window, displaying
the ShopTurn program steps.
