Demand Analysis of Machine Vision Measurement Technology for the Processing of Conductive Slip Ring

machine vision methods are widely appliedin detection tasks during the machining process, such as indexing fixture anglemeasurement, gear profile inspection, crankshaft processing, headphone jackmanufacturing, intelligent grinding, and cnc machine tool automatic tool alignment.in earlier years, traditional manual lathe machining of conductive slip ringcopper rings had many drawbacks. therefore, the introduction of machine visionmethods in the manufacturing and inspection of conductive slip ring copperrings not only ensures higher accuracy and efficiency but also avoids thesubjectivity and individual differences associated with manual inspection.

to address the challenges faced during themachining process of precise conductive slip ring grooves, a positioningsolution based on image measurement and analysis principles has been proposed.this solution utilizes machine vision methods to obtain the cutting positionfor each pass and ultimately generates the g-code required for machine toolprocessing, achieving the automation of precise conductive slip ring groovemachining. as a method for automation in the process of conductive slip ringmanufacturing, machine vision measurement technology demonstrates rationalityand scientific basis but also complexity. the following analysis delves intothis issue.

the process of measuring and machiningconductive slip ring grooves within the machine involves several cumbersomesteps. the specific process is as follows: 1) mount the precise conductive slipring onto the lathe. 2) install the measuring head on the machine tool andposition it at the initial location. 3) capture four sets of images at theinitial position of the slip ring, 90°, 180°, and 270°, respectively. 4)process each set of images and calculate the average values of the four sets ofdata. 5) based on the measurement results and the machine tool's movement mode,calculate the machining position of the groove and generate the correspondingg-code. 6) remove the measuring head, install the machining tool, and run themeasurement g-code for machining.

To ensure precise measurement and controlof conductive slip ring groove machining using machine vision measurementsystems, a complex hardware setup is required. This setup includes industrialcameras, dual-telecentric lenses, lighting sources, mechanical structures, andmeasurement fixtures, among others. Undoubtedly, this increases costs, and thecomplexity of the system also introduces risks of reduced stability. Therefore,when applying machine vision measurement technology, it is necessary to enhanceits reliability and ensure long-term stable operation before deployment, whichinevitably adds to the costs. However, in the current context, intelligenthigh-end machine tools have been widely adopted in the field of mechanicalmachining. For the processing of conductive slip ring copper rings, complexmachine vision measurement technology is generally no longer required.
