MODERNIZATION OF THE UNIVERSAL MEASURING MICROSCOPE MODEL UIM-21 FOR USE IN PRESICION MECHANICS

Abstract

In precision mechanics, measuring microscopes are widely used to determine mechanical parts' linear and angular dimensions in perpendicular Cartesian coordinates or polar coordinates. Currently, many older-generation measuring microscopes have degraded optical systems, making the measurement process difficult, and causing large errors, the calculations are done manually, leading to low measurement productivity. Research aims to modernize these devices by replacing the classic optical measuring system with an electronic optical measuring system and building calculation support software to restore degraded functions, and improve performance and accuracy. The measurement software is developed using the Graphic programming language, integrating basic measurements based on data from the linear scale system, allowing storage of results and measurement information. The modernized measuring microscope has important measurement parameters such as measuring range up to 200 mm, resolution 0.0002 mm, and error not exceeding (3 + L/30) µm where L is the length measured in mm. Specialized measurement software helps decrease the time required for each measurement, enhances productivity, and offers greater convenience to users.
