Abstract

The urge for achieving highe productivity of domestic production alongside broadening o poduct assortment conditions more intense application of numeical NC and compute numerical control CNC machines and of basic devices for automation of small serial and medium serial production as dominating ways of production. It is, thereore easy to undestand the attention being paid to installing a bigger number of CNC machines in the production process in the last few years, whose development is in close connection to the development of electronics and computing technique. Computer controlling presents the basic automation of a working process. All the pieces of information necessary for controlling and working process realisation that are programmed are systemised and coded in the form of a programme. They are entered in the memory of a controlling system. The basic elements of the design process in industrial practice are graphical simulations of a working process on CNC machines, which are most frequently presented by an independent software, depending on the applied control type. The independent Win3D-View software, version 2.00 with basic characteistics and possibilities presented in the paper on the example of turning has also been developed for that purpose. The software has been created for the purpose of the 3D graphical simulation of turning and milling on CNC machines and it is most frequently integrated with WinNC and WinCTS software. The working process that is graphically simulated on the CNC machine is previously programmed in SINUMERIK 810T controlling format (or in one of the following types of control: SINUMERIK 820T, GE FANUC Series 0-TC, EMCOTRONIC T2). The graphical simulation, primarily designed for industrial use, realistically presents the working process, unmachined part, tool, clamp device, and different views and sections of a processing piece. A library with standard tools is formatted during the software installation, from which all the tools necessary for the processing are chosen. It is also possible to create one’s own tools for the 3D simulation. The paper presents a modelling procedure of a typical tool for turning.
