| Abstract | ||
| Turning machine vibration is an old problem on manufacturing processes. Unless avoided, vibrations may cause large dynamic loads damaging the machine spindle, cutting tool, or work-piece and leave behind a poor surface finish. This work intended mainly to measure the random vibration in various cutting tool length . Accelometer fixed in different points along the tool-piece to test the effect of distance from the fixed point on random vibration . A USB vibration analyzer and using a specialized program the data obtained analyzed for many random vibrational parameters (acceleration RMS, velocity RMS ,displacement RMS and maximum frequency ) .Different speed for the turning process are used (40 ,125,180 and 540 rpm ) .Result shows increasing behavior for acceleration , velocity and displacement with decreasing behavior upon decreasing distance from fixation point and decreasing behavior for maximum frequency reached. Also, a Finite element model was suggested using ANSYS 14 to simulate the cutting tool displacement and von-Miss stress distribution . | ||
