The final work "Machining of product nr. KG-00 on CNC Lathe" shows the implementation of modern technologies and equipment in industrial production that man has invented to help in mechanical engineering and in everyday life. The final work presents the history of the formation and development of NC and CNC machines. The development of numerical machines monitored and the development of 3D software in order to faster development of products from concept to test samples. In the process of formation of products, 3D software have accelerated the process of design, optimization and manufacturing. This work shows the practical example of creation of NC programs and products on the lathe "Hwacheon Hi-Tech 450BL YMC", the difference between programming machines with "Fanuc 0i" and Hurco "WinMax" management and programming advantages of machines using a PC with CAM software. The aim was to compare the time of programming and production times (simulation creation) in the preparation of the selected object on a single machine, and using several modes of programming.
