1.1 smart.Turn and ISO Programming
NC blocks begin with an N followed by a block number (with up to five
digits). The block numbers do not affect the sequence in which the
program blocks are executed. They are only intended for identifying
the individual NC blocks.
The NC blocks of the HEADER and TURRET sections are not included
in the block number organization of the editor.
Program branches, program repeats and subprograms can be
used to structure the program (example: machining the front/back of
a bar, etc.).
Input and output: With “input” you can influence the flow of the NC
program. Using “output,” you can communicate with the machinist.
Example: The machinist is required to check measuring points and
update compensation values.
Comments are enclosed in brackets “[...].” They are located at the
end of an NC block or in a separate NC block.
You can also enclose more than one program line in square brackets
to mark them as a comment. To do this, enter a comment containing
the character “[” and conclude the section by entering another
comment containing the character “]”.
