Plastic Deformation, Mechanical and Adhesive Properties of Bio-Plastic Material

Given the added need for eco-friendly material, environmental scientists are constantly on the look-out for new solutions. In this respect, biodegradable polymer proved to be a promising one. The Selfix material, being a bioplastic, is biodegradable and, unlike other plastic products, can be considered feasible for the industry as a smart material capable of biodegrading at the end of its life cycle. Using Selfix, waste paper can be re-used, thus eliminating the need for recycling and helping to reduce the CO2 emissions. The present paper develops 3D models with Selfix material to offer benefits such as easy-cutting and sticking properties in a way that can be educational for children. We examine the mechanical properties of this material using tensile testing, laser-cutting, CNC milling, surface roughness and also scanning electron microscope or SEM.

CNC part program simulation using solid modelling techniques

CNC programming on all but the simplest cases needs graphical verification or simulation. The programming paradigm advocated for this task is line-by-line execution of the program with simultaneous creation of the volumes swept by the cutting tool and their subsequent subtraction from the volume of the initial material block. Tool movement is defined following ISO (or G-) codes and auxiliary commands are supported, too, e.g. tool change. A library of tools is maintained and can be easily expanded. The system exploits Boolean operators (notably subtraction) and solid creation operators (extrusion, revolution) as well as solid manipulation operators (3D rotation, offset etc.). The prototype system was created as an Autocad extension using Autolisp and DCL for user interface development.
