[Abstract]:Through the analysis of the standard deviation of the standard deviation and the standard deviation of the measurement system and the acceptance criteria of the three indexes in different cases, the interval distribution diagram of the comprehensive evaluation system was constructed. According to the distribution of the measured data in the interval distribution, the process capability of the manufacturing system is analyzed, the measuring capacity and the measuring accuracy of the system are measured, and the feasibility of the measurement system is determined, and the improvement suggestions are put forward. The paper puts forward the comprehensive evaluation system of the quality of the part in the machine measurement system, which is applied to the automatic production line of the motor end cover developed by the independent R & D, and the inner diameter of the machine is tested and evaluated. The improved process capability index is improved to 1.18, the measuring capacity is 11.29%, the measurement accuracy is 9.64%, and the automatic production line has higher production efficiency and economy and meets the requirements of product batch production. The results show that the comprehensive evaluation system of the machine measurement system has good feasibility and practicability in the evaluation of the measurement system of the automatic production line of the parts.
