Gage Repeatability & Reproducibility (Gage R&R) is a useful technique in industry that is used to determine the adequacy of a measuring system. Generally, Gage R&R involves multiple operators taking multiple measurements of a particular feature. In this paper, Gage R&R of CMM is undertaken wherein the operator is replaced by three different factors which can affect the measurement like Location, Probe Diameter and Touch Speed. Internal Diameter, Overall Length, Parallelism and External Diameter of ten components were measured during the R & R study. The study revealed that percentage contribution of variance component due to Reproducibility was less than 2.18% thereby assuring that the change in location, probe radius or touch speed would not have a significant effect on the measurement of the features mentioned. This analysis would help industry to determine if measurement due to any of the above three factors is reliable.

量具的可重复性和可重复性（量具R＆R）是工业上一种有用的技术，用于确定测量系统的适用性。通常，Gage R＆R涉及多个运营商对特定功能进行多次测量。在本文中，进行了CMM的Gage R＆R，其中，操作员被三个可能影响测量的不同因素所代替，例如位置，探针直径和触摸速度。在R＆R研究期间，测量了十个组件的内径，总长度，平行度和外径。该研究表明，由于重现性引起的方差成分的百分比贡献小于2.18％，从而确保了位置，探针半径或接触速度的变化不会对上述特征的测量产生重大影响。
