Programming POSITIP
PROGRAMMING AND EDITING
operating mode
The functions available in the
PROGRAMMING AND EDITING
oper-
ating mode are divided into four groups:
• Programming mode
for entering and editing programs
• Teach-In mode
• External mode
for transferring programs to an external data carrier
• 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
blocks. A single program can contain a maximum of 1000 blocks.
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 retype them. You can also
transfer programs to a personal computer or printer.
Programmable functions
• Nominal position values
• Program interrupts
• Bolt hole circles and linear hole patterns
• Rectangular pocket milling
• 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.
• Subprograms:
A section of a program only has to be entered once and can
then be run at various points in the program as often as desired.
• Tool call
Transfer position: Teach-In mode
This mode allows you to transfer the actual positions of the tool
directly into a program. The nominal positions for workpiece ma-
chining and the positions you probe with the HEIDENHAIN
KT Edge Finder can also be transferred 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
EXECUTE PRO-
GRAM
operating mode. See chapter I - 5 for an explanation of this
mode.
