6.1 Tool Movements
6.1 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.
FK Free Contour Programming
If a production drawing is not dimensioned for NC and the dimensions
given are not sufficient for creating a part program, you can program
the workpiece contour with the FK free contour programming and
have the TNC calculate the missing data.
With FK programming, you also program tool movements for straight
lines and circular arcs.
Miscellaneous functions M
With the miscellaneous functions of the TNC you can control:
n Program run, e.g., a program interruption
n Machine functions, such as switching spindle rotation and coolant
supply on and off
n Contouring 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 9.
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 10.
