	abstract="{This paper presents a dimensional analysis of die castings made from AlSi12Cu1(Fe) alloy. The machining process was optimized to
minimize downtime and equipment usage while maintaining product quality and production efficiency. The castings, shaped as hydraulic valves, were produced using a four-cavity die-casting mold. Due to difficulties in achieving the required geometric dimensions, each casting from a specific cavity was machined on separate Computerized Numerical Control (CNC) machines. This work focuses on the dimensional analysis of castings from each mold cavity and the optimization of the production process. Based on the analysis, it was observed that the castings could be divided into two distinct groups: the first group contained castings that, after machining, exhibited similar measurement values and remained within the specified dimensional tolerances, while the second group failed to meet the required tolerances. As a result of the conducted analysis, a new machining strategy can be proposed—assigning castings from each group to different CNC machines. This would eliminate the need for frequent machine retooling and significantly reduce production downtime. The findings point to a potential solution for optimizing the machining process and improving overall manufacturing efficiency.}",
