Abstract
This research presents the dry turning machining to observe the workpiece profile
of the AISI 305 by adopting ceramic insert as a cutting tool. The machining was
conducted fifth passes throughout the experiment using same specimen and cutting
insert. The image of ceramic insert before machining and after every each pass of
machining were captured under Scanning Electron Microscope (SEM) to observe the
performance during machining operation. The image of workpiece is captured by using
high resolution of DSLR camera with assistant of backlighting to obtain high quality of
workpiece profile. Appropriate setting of backlighting is significant to obtain a good
quality of image processing. The image of the workpiece will be extracted into
simulation programming to obtain the autocorrelation profile. From the autocorrelation
function profile, the surface profile will be observed to detect the gradual wear of tool.
The workpiece surface profile is examined using stylus and vision method to verify the
profile. Vision method is the most accurate measurement method compared to stylus
due to some limitations of the equipment.
