Virtual Device for Assessing the Geometric Parameters’ Reliability Control for Mechanical Products Depending on the Tool Accuracy

There is an urgent need for remote tools and research methods in the current conditions of training qualified specialists for work in the engineering industry. Therefore, this work aims to create a virtual device for assessing the reliability of control of the product’s geometric parameters. The Monte Carlo approach was applied jointly with the simulation of control procedures. The software environment NI LabVIEW 7.1 is used to automate the computer modeling. The virtual device opens up the possibility of predicting the range of values of the selected control reliability criterion depending on the technological forming system’s accuracy. It limits the measuring device’s error under certain assumptions about the type of random argument distribution. The ratio of the sum of correctly rejected and correctly accepted products to the total statistical sample is proposed as a control reliability criterion. An algorithmic model of a computer experiment was proposed. It was also implemented in the Flat Sequence Structure of the LabVIEW program, which consists of a certain number of subdiagrams or frames executed sequentially. The study aims to determine the dependence of the selected reliability criterion on the maximum permissible limit of random measurement error. Scientific novelty: graphs showing the dependence of the selected reliability criterion on the maximum permissible limit of random measurement error under specific initial data and limitations in process modeling. Practical implementation: The created virtual device allows a series of computer experiments.
