Lead time reduction and increasing productivity by implementing lean manufacturing methods in cnc processing center

Abstract

Growing competitiveness of manufacturing companies has led companies board to look for new innovative solutions to increase the productive efficiency. More and more companies are looking to maximize profit through different ways, some of them use classical methods that are focused on increasing production capacity, expanding the product portfolio, manufacturing and marketing campaigns, other operational activities, are implementing modern techniques to reduce losses. This paper propose to present the way that productivity is increased by reducing lead time through Lean Manufacturing method implementation. For this purpose a piece will be manufactured using a CNC processing center, which will contribute significantly to processing the part at a higher precision, and at the same time eliminating the down times. To highlight the contribution and the efficiency of the CNC processing center, will be present the classic production method using a classical milling machine, respectively FUS 22, the method that was also implemented, according to this case study. To analyze and graphically illustrate these two production methods, respectively classic and modern methods, VSM will be built, then the 2 methods will be compared.

Effective implementation of Japanese quality methods during health pandemics

“…Lean thrives on analyzing and standardizing processes, eliminating waste and creating value. It has been proven to help organizations in every aspect of its operations to improve service, reduce cost, minimize errors and improve profitability (Graban, 2012; Womack and Jones, 1996; Gherghea et al , 2019).…”

“…Gemba is a Japanese world that means workplace, but the true meaning of gemba in lean is to make sure the workplace thrive with continuous enhancements. Under this concept, the workplace is a place that does not have any work or health flaw (Gherghea et al , 2019).…”
