Application of the engraving machine in education has brought a new view into the technology of material cutting. Students can compare possibilities of manual cutting and cutting done by the computer programme. This innovative method brings new externalities not just in the area of technology but in the cognitive area of education of technical thinking too. The programming of the engarving machine leads to recognition of machine cutting limits, it compares ideas of students with realisation of objects. The paper deals with the technical parameters of the machine and esential information that accompanies teaching of operation and work. It includes didactic order of realisation of the topic for education.
