The article presents a comparison of manual programming CNC machine tools and programming through the use of dedicated software packages. Introduce the use of presentation software package for the manufacturing of the product by milling. The aim is therefore to present the possibilities offered by modern software. The learning process takes place step by step: modeling product suitable for milling, G code programming manual, G code programming with control software, control manufacturing milling software. Students in the program mechanical technician can use this software for immediately verify whether the write appropriate program for the control or not. In this way, they can also find their mistakes and try to eliminate them. The work takes place much faster than without such software.
