Prikazan je postupak rekonstrukcije konvencionalne tokarilice Hobbymat MD65 u CNC (Computer Numerical Control) stroj s dvije simultane osi ugradnjom koračnih motora tipa NEMA 23 i upravljanih PC programskim sustavom Mach3-Lathe. 3D model je izrađen u programskom alatu Solid Edge ST4 – Ordered Technology, a fotorealistički prikaz modela u programskom modulu ERA (ExplodeRenderAnimate). Na temelju dokumentacije o montaži i održavanju i mjernih skica izrađena je kompletna 2D tehnička dokumentacija stroja. U programskom alatu AutoCAD Mechanical i programskim modulima Shaft Generator i Shaft Calculation izrađen je kontrolni proračun naprezanja vratila stezne glave, a analiza naprezanja- FEA u programskom modulu Femap – Solver NX Nastran.A process of reconstruction for conventional lathes Hobbymat MD65 in CNC (Computer Numerical Control) machine with two simultaneous axes installing stepper motor type NEMA 23 and managed PC programming tool Mach3-Lathe is presented in this paper. A 3D model is created in the programming tool Solid Edge ST4 – Ordered Technology, and realistically display models is created in the programming module ERA (ExplodeRenderAnimate). Complete 2D technical documentation of the machine was made based on the documentation on the installation and maintenance of measuring and drawing. The software tool AutoCAD Mechanical and program modules Shaft Generator and Shaft Calculation are used for controlling stress calculation returned chucks and FEA stress analysis in software module Femap – Solver NX Nastran
