...JiAn Duan; DeFu Liu The purpose of this paper is to reveal material removal mechanisms of optical fiber end-surface in lapping processes. The lapping process experiments are conducted using fixed diamond abrasive lapping films with various particle sizes of 6 μ m , 3 μ m , 1 μ m , and 0.5 μ m...

... in the tool insert from the underside to near the rake face, and an optical fiber is inserted in the hole. One of the optical fibers runs through the inside of the machine tool spindle and connects to the other optical fiber at the end of the spindle. Infrared rays radiating from the bottom of the hole...

... unacceptable welds as they are formed. Because LU systems are non-contacting, they can be used for testing moving specimens or for operation in hazardous and/or high temperature environments. A highly versatile system can be created when an optical fiber delivery system is incorporated into the design...

...S. K. Choudhury; V. K. Jain; S. Rama Krishna The present work deals with on-line monitoring of tool wear and control of workpiece diameter so as to avoid the formation of taper in the machined job. A noncontact, displacement optical fiber transducer is developed to monitor the tool wear indirectly...
