Programming POSITIP
Operating mode PROGRAMMING AND EDITING
The available functions in the PROGRAMMING AND EDITING
operating mode are divided into four groups:
•
Programming mode
for entering, running and editing programs
• Teach-in mode
• External mode
for transferring programs to an external device
• Deleting programs
Programs contain the work steps for workpiece machining. You
can edit programs, add work steps to them and run them as often
as you wish. POSITIP can store a maximum of 20 programs with a
total of 2000 nominal positions. A single program can contain a
maximum of 1000 nominal positions.
The External mode enables you to store programs with the
HEIDENHAIN FE 401 floppy disk unit and load them into POSITIP
again on demand — you don't need to re-enter them manually.
You can also transfer programs to a personal computer or printer.
Programmable functions
• Nominal position values (axes with saddle and top slides:
nominal value of the summed position, see “Selecting position
display modes” in Chapter I - 2)
• Interrupt program
• Multipass cycle:
Turning with any number of feed moves.
• Program section repeats:
A section of a program only has to be entered once and can
then be run up to 999 times in succession.
• Subprogramming:
A section of a program only has to be entered once and can
then be run at various places in the program.
Transfer position: Teach-in mode
This mode allows you to transfer the actual positions of the tool
directly into a program. In many cases the Teach-in function will
save you considerable keying effort.
What happens with finished programs?
For workpiece machining, programs are run in the operating mode
EXECUTE PROGRAM . See Chapter I - 4 for an explanation of this
mode.
