3D touch probes
The TNC provides the following features when
used in conjunction with a 3D touch probe (see
Chapter 9):
• Electronic workpiece locating (compensation
of workpiece misalignment)
• Datum setting
• Workpiece measurement during program run
• Digitizing 3D surfaces (option)
• Tool measurement with the TT 110 touch probe
Floppy disk unit
With the HEIDENHAIN FE 401 floppy disk unit you
can store programs and tables on diskette.
It is also a means of transferring programs which
were created on a personal computer.
With the FE 401 you can transfer programs that
were written on a PC to the TNC. Very large
programs that exceed the storage capacity of the
TNC can be “drip fed” block-by-block: The machine
executes the transferred blocks and erases them
immediately, freeing memory for more blocks from
the FE.
Electronic handwheel
Electronic handwheels give you manual control of
the axis slides. Similar to a conventional machine
tool, the machine slide moves in direct relation to
the rotation of the handwheel. A wide range of
traverses per handwheel revolution is available.
Portable handwheels such as the HR 330 are
connected via cable to the TNC. Integral hand-
wheels such as the HR 130 are built into the
machine control panel. An adapter permits connec-
tion of up to three handwheels.
Your machine manufacturer can tell you more about
the handwheel configuration of your machine.
