Optointerferometry measuring techniques are one approach to carefully regulate the geometric correctness of machine tools (both traditional and CNC operated). These can be compared to the CNC lathe's measurement results (linear motion deviation), the CNC milling machine's measurement results (dynamic behavior), the deep drilling machine's measurement results (linearity), and the CNC milling machine's measurement results (comparative measurement linearity according to two different measurement methods, interferometry and CNC method). Optical measuring techniques are employed in machine tool metrology to quantify the angular and linear volumetric inaccuracies of machine tools. Several approaches are employed based on the size and specifications of the measurements. Interferometry, phase shifting techniques, triangulation, and time-of-flight measurements are some of these approaches. Optical comparators are a type of optical measuring device used for inspection and measurement in the manufacturing industry. Optical comparators and measuring microscopes are non-contact optical measuring tools that use images to perform optical measurements. These machines use image processing technology to perform automatic measurements that are both fast and highly accurate. As factory automation in production areas progresses steadily, the development of these measuring devices also increases rapidly. The key feature of optical comparators is that they have two-dimensional measurement capabilities (X and Y directions), unlike hand tools such as micrometers and vernier calipers or height/depth gauges, which are limited to measuring in only one direction at a time. Optical comparators can perform measurements of flexible parts without distorting them or damaging sensitive parts. During the inspection process, nothing other than light touches the part, so there is no potential for the part to bend or change shape. Optical measuring devices are important not only because of their precise measurements, but also because they have the ability to check faulty parts in production lines. Newer versions use highly sensitive CCD cameras to enable observation of color images.
