For G69T engineering and construction was used a Cad-Cam software, a modular system for CNC tool machine. Using it is possible create complex manufactures. The main 4 steps to obtain a single manufactured part are:

1- PARTPROGRAM
A Partprogram defines, using specifical instructions, geometry and technology of the part to work. These instructions are really a program language.

2- PROCESSOR
The Processor translates the Partprogram instructions, controls syntax, defines and generates tool ways.

3- SIMULATOR
The Simulator is an important Cad-Cam section, permitting the tool way visualization, controlling the exact working executions (often with more tools) and watching for possible toll-piece collisions. Great simulation importance is verifying the right raw material removal. The simulated tool way will be accurately reproduced during the CNC tool machine working.

4- POST-PROCESSOR
The Partprogram language is translate from the Post-Processor; it generates the file containing tool machine CNC instruction. The file is transferred to the tool machine control unit, that understands it and works to make up the programmed manufactures.
