FEKT-NTMSAcad. year: 2018/2019
Mastering the work through the electronic product definition method. As opposed to the classical way of Technological Preparation of Production, when the development of the product as a whole is carried out by several workgroups and minute co-ordination of the activities is necessary, this method represents a solution that connects the individual „isles“ into one logical whole from the form of the design to the connection with the production itself. The teaching in the created simultaneous environment, common work on one task. Simulating activities from practice, where the individual teams work together on one task, although they are not resident in the same place.
Simulating the technological preparation of production, analyis with the input of the simulation programs into the process of technological preparation of production, simulation of kinematics, finite element method, finite volume method, heat conductivity.

Solution of a task by the Electronic Product Definition method
Until now, the main problem in implementing CAD/CAM/CAE technologies has been the focus on solving only one concrete issue. Customer who wanted to speed up the Technological Preparation of Production selected a CAD system to suit these specific needs. The system must be able to support individual tasks but the real benefits (including a financial one) can be achieved only when a complete solution is applied which interconnects all processes into one logical whole. The new method consists in introducing th electronic definition of the product (EPD). A traditional CAD system becomes a part of this solution. EPD makes it possible to logically link all the individual applications. There are more and more companies interested in EPD. Its complexity changes the status quo in this area to such extent that especially big companies do not look for a CAD provider, but for a partner who will help them create an EPD system. Therefore there is a strong pressure from the industrial practice for universtiy graduates to be knowledgeable in this area. We teach large CAD systems in the context of EPD from the Sketcher to CAM manufacture. The course aims to teach students the basics of this method. The basic modules - which constitute the backbone of EPD - are as follows: SKETCHER - serves for easy 2D sketching that can be transferred to a parametric modeller. PARAMETRIC MODELLER - for solid model creation. ASSEMBLY - models are put together into assemblies in this environment. It also makes it possible to make additional changes in individual models. The EXPLICIT environment serves for creation of basic technical documentation of the models. The MANUFACTURE module compiles a binary code for each model which can be compiled into NC-code and control NC machines. The production process can be first simulated in an NC verifier In the past, it was necessary to make a real working model for testing.. ANALYSIS MODULES simulate various features, making this unnecessary and saving costs and time. The courses present large CAD as a complete set of tools for literally materialising an idea.
