A Scientific Approach of using the DMAIC Methodology to Investigate the Effect of Cutting Tool Life on Product Quality and Process Economics: A Case Study of a Saudi Manufacturing Plant

One of the major priorities for manufacturing companies in globalized economy is ability to offer high-quality products customers at lowest production cost. Globally, process improvement methods and techniques are used reduce waste improve product service quality. This paper aims propose a systematic model based on methodologies tools help decide cutting tool life other issues. research seeks prove that some common industry practices, such as changing machining processes, can significantly affect economics overall performance plant. The mainly analyzing real field data using DMAIC methodology identify improvements order achieve balance between quality Saudi Although study was concerned only with an air conditioning plant, its findings conclusions be generalized all processes.
