Any Entry Into Program (Mid-Program Startup) - HEIDENHAIN TNC 320 User Manual

Any entry into program (mid-program startup)

The RESTORE POS AT N feature must be enabled
and adapted by the machine tool builder. Refer to
your machine manual.
With the RESTORE POS AT N feature (block scan) you can start a
part program at any block you desire. The TNC scans the program
blocks up to that point. Machining can be graphically simulated.
If you have interrupted a part program with an INTERNAL STOP,
the TNC automatically offers the interrupted block N for mid-
program startup.
Mid-program startup must not begin in a
subprogram.
All necessary programs, tables and pallet files must
be selected in a program run mode of operation
(status M).
If the program contains a programmed interruption
before the startup block, the block scan is
interrupted. Press the machine START button to
continue the block scan.
After a block scan, return the tool to the calculated
position with RESTORE POSITION.
Tool length compensation does not take effect until
after the tool call and a following positioning block.
This also applies if you have only changed the tool
length.
