| Summary: | This report is an assessment approach, which presents the experimental results to
measure roughness of machined surface using a laser which is a non-contact method
measurement. There are two specimens has been tested which is mild steel and
aluminum. Usually, surface roughness is measured in average height of roughness (Ra)
and root-mean-square (Rq) for non-contact method measurement. But in non-contact
method, the parameters used are average pixels and standard deviation of the profile line.
The objectives of this report are to compare the results of the two different methods. Then
observing the graph line whether it has some trend or pattern. In order to do this, the
contact method is been carry out followed by thee non-contact experiment by using the
same specimens. The specimens are machined in some different parameter to see the
effect to its surface roughness. This work also presents the use of some programs such as
DT-Acquire 2 for image grabbing and Matrox 2.1 which is to do some image processing. |
