1. Non-contact, in line inspection of the surface finish of crankshaft journals Hagay Bamberger ; En Hong ; Reuven Katz ; John S.Agapiou ; Susan M.Smyth הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY Presenting: Gilad Gal Yuval Kaminer

2. Discussion Topics הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY The Crankshaft: Crankshaft’s requirements. Experiment objective: Go No-go. Shaft Crank_Pin Oil hole

3. Mass inspection in Mass production Mass production without loosing product quality. Mass inspection. Automatization. הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY

4. On the agenda High Volume high quality product. Unpredictable machining failure. Low reliability and second hand inspections (as of the moment). הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY

5. The proposed solution - Basics Camera based high resolution vision inspection method. Unaffected by external disturbances – such as ambient light. Fully automated. High reliability. Roughness – Reflection connection. Blue light source wavelength array. הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY

6. The proposed solution proof of concept Illuminating the crankshaft with LED light. Placing the camera above the center. Image processing the light reflected from the object. Analyzing the results and defining a go no-go criteria. הטכניון – מכון טכנולוגי לישראל TECHNION – ISRAEL INSTITUTE OF TECHNOLOGY
