Abstract
The method of laser powder bed fusion (LPBF) is an additive manufacturing process and allows great freedom of component geometry due to the layer-by-layer structure. The LPBF components are printed on a substrate plate and must be separated from the plate afterwards. Support structures are used to attach LPBF components to the substrate plate and to sustain overhanging parts. The cutting of the components is mainly carried out by means of a sawing process using the support structure. The forces occurring during this process are very challenging because the component has to be cut off without damage or deformation. The present study investigates and discusses the resultant forces and vibrations during the sawing of LPBF components made of titanium alloy Ti6Al4V using two different support structures. The components were arranged on the substrate plate at angles of 0°, 5°, 10°, 15°, 45° and 90° to the direction of primary motion.
期刊介绍:
ournal of Machine Engineering is a scientific journal devoted to current issues of design and manufacturing - aided by innovative computer techniques and state-of-the-art computer systems - of products which meet the demands of the current global market. It favours solutions harmonizing with the up-to-date manufacturing strategies, the quality requirements and the needs of design, planning, scheduling and production process management. The Journal'' s subject matter also covers the design and operation of high efficient, precision, process machines. The Journal is a continuator of Machine Engineering Publisher for five years. The Journal appears quarterly, with a circulation of 100 copies, with each issue devoted entirely to a different topic. The papers are carefully selected and reviewed by distinguished world famous scientists and practitioners. The authors of the publications are eminent specialists from all over the world and Poland. Journal of Machine Engineering provides the best assistance to factories and universities. It enables factories to solve their difficult problems and manufacture good products at a low cost and fast rate. It enables educators to update their teaching and scientists to deepen their knowledge and pursue their research in the right direction.
