520	3		_aControl charts are basic tools in industrial statistics to statistically assess performance-related parameters of a machine or process. The objective of this project is to evaluate the reliability of the CNC machine in the UMP lab using the concept of quality control, namely 𝑥 and R. In order to develop the control chart, a number of identical round bars will be generated on titanium in different environments. The measured data used for 𝑥 and R are diameter and surface roughness. For machining tests, all of the machining experiments were carried out on ROMI C420 CNC turning machine. The machining parameters are set based on literature. Diameters of the bars are measured with digital micrometer and the surface roughness by using perthometer. A total of 60 data for each bar was collected. In control chart, 20 samples of size 3 were used. The control charts were plotted manually as well as in STATISTICA. It has been found that reliability of the machine tested depends on the control limits defined and tolerable part dimensions.
