The Effectiveness of Implementing a Milling Process in Reducing Production Process and Costs: A Case Study

Every product's design has a different process flow. Sometimes, designed products consist of a repeated process flow. Repeated processes are a problem that can affect production management and production output. This study has potentially proposed a new process that can replace the existing process by adding a milling process. The result shows that introducing a milling process was added to item 2 to produce a step slot and reduced the number of items used (Item 3). The assembly of Item 2 and Item 3 was converted into Item 6, which showcases a more substantial time differential, with the existing process taking 12.25 minutes and the new process requiring 0 minutes. The additional process of the new alternative milling machine reveals lower Watt, less time duration for the welding machine, reduced energy consumption for a hand-grinding machine, and lower cost demand for the welding machine than the existing process. In addition, the total cost of the added milling process shows a slight reduction in overall cost and is associated with energy consumption.
