PROCESS CAPABILITY EVALUATION OF SHAPED METAL DEPOSITION INTEGRATED SYSTEM THROUGH CONTROLLING THE DIMENSIONS OF FABRICATED PARTS OF AUSTENITIC STAINLESS STEEL
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2016, Vol 5, Issue 2
Abstract
The aim of this work is to investigate the process capability of the shaped metal deposition processes to be able to fabricate products with geometries meet the required specifications of the designed parts. The intent of the present paper is to highlight the using of the statistical techniques and process capability for the continuous current and pulsed current TIG-based shaped metal deposition processes in order to achieve the suitable performance. Two experiments with different sets of deposition process parameters were carried out in order to study the capability of the SMD processes at different conditions. The results showed that all the experiments were performed under statistical control state. The parts produced by PC-SMD method are very close and consistent with the target specification comparing to the CC-SMD method. However, the CC-SMD produces wall with lower side wall machined layer less than that of PC-SMD process. As results the CC-SMD method is recommended for future usage sine it give more saving in the metal removal during further machining processes.
