Tool movements

Path functions

A workpiece contour is usually composed of several contour
elements such as straight lines and circular arcs. With the path
functions, you can program the tool movements for

straight lines

and

circular arcs

.

Miscellaneous functions M

With the TNC's miscellaneous functions you can affect

the program run, e.g., a program interruption

the machine functions, such as switching spindle rotation and
coolant supply on and off

the path behavior of the tool

Subprograms and program section repeats

If a machining sequence occurs several times in a program, you
can save time and reduce the chance of programming errors by
entering the sequence once and then defining it as a subprogram
or program section repeat. If you wish to execute a specific
program section only under certain conditions, you also define this
machining sequence as a subprogram. In addition, you can have a
part program call a separate program for execution.

Programming with subprograms and program section repeats is
described in Chapter 7.

Programming with Q parameters

Instead of programming numerical values in a part program, you
enter markers called Q parameters. You assign the values to the Q
parameters separately with the Q parameter functions. You can use
the Q parameters for programming mathematical functions that
control program execution or describe a contour.

In addition, parametric programming enables you to measure with
the 3-D touch probe during program run.

Programming with Q parameters is described in Chapter 8.
