Application of CAM systems to simulate of a milling machine work

Abstract

Mechatronic is an interdisciplinary science which consist of subsystems like mechanics, electronics and theory of control. CAD/CAM systems are mechanics and theory of control resulted of synergy, so they are also a part of mechatronic. CAM means Computer Aided Manufacturing so it is useful to make simulation of manufacturing process and machine work. The subject of the work is to create a model in CAM program and next simulate the operation of this model. The CAM model can be use for programming numerical control machine using G-code (generated by CAM program). As an example it is propose a milling machine, which was made in the NX program using a special postprocessor. That model can simulate real work of that machine using set displacement parameters. The model was used to produce simple shaped product. The aime of the work is to generate a path of real milling tool and most precise mapping work of the real machine center. That aim was established in that form has been obtained. The created model is working and allowing to make simulation of individual product manufacturing, not exceeding the maximum of the axes values and keeping all of the parts according constrains. In the future the project could be expand in more complicated shape of product and use more complicated milling model machine (for example 5-axes milling center machines).
