TCL and more to learn


Hello Everyone;


Up to now I have succeded to write post processor file for our Mitsubishi M70 control unit for 3 and 4 axis milling machine. I have jusy arranged G codes adding additional T, Z, M codes etc. or change the order. Sometimes at the start of each operations I have to change some codes before sending the shop.  Actually it is enough for our factory. It is okey but I want to learn more about post builder.

Also I have't write any TCL command by myself. 

How can I learn tcl command?

What can I do and where to start to learn and write more sophisticated post processor using post builder or post configurator?

like to read people want to learn more :-)

You can start watching some videos in the separate post discussion group.
Some stuff to start with some information.

The final step would be to attend a post-processor developer training.

This allows you to create a post-processor for one particular machine of yours with the help of someone more knowledgeable.

Videos are good, but they don't answer questions they don't cover.

If you want to learn tcl, search the web for tcl tutorials.  Or buy a book.  (Brent Welch's book is typically considered very good, although it covers a LOT of stuff you'll never need for post development)

Siemens training offers a course covering post builder (see for US/Americas)

Siemens Learning Advantage (I think) has a lesson on Post Configurator (

There are a bunch of videos in the tech tips part of this manufacturing forum.


Besides posting itself, you'll want to learn how UDEs work, and know how NX CAM operations work (so if you need to do something, you can figure out if it would be better to set a parameter in an operation/tool/geometry/method parent, of if you need a UDE to add additional data).

NX comes with a set of TclTK manuals.


look in C:\Program Files\Siemens\NX 12.0\POSTBUILD\tcl and un zip theTclTk8.0Manuals


There are several books you can get, even Tcl/TK for Dummies
