| 總結: | High-quality products and shorten manufacturing lead time are very important factors addressed
by many companies. Typically, low-quality products are induced by inconsistent of manufacturing process
performance. To get a constant laser power in Infrared (IR) Laser Marking process was a common problem
facing by many engineers in the manufacturing industry. This consequences might effect on laser marking
characteristics such as the possibility of burn marking or blur marking particularly on the products.
Therefore, the objective of this paper is to study the interaction between Infrared (IR) Laser Marking input
parameters such as current (amp), frequency (Hz), water flow (l/min) and laser beam size (mm) on laser
power (watt) as the main response. Furthermore, the response of laser power from Infra-Red laser process
can be predicted when all combinations of parameters are tested. The IR marking machine was deployed and
experimental studies were conducted in order to meet this objective. The experiments were based on Design
of Experiment (DOE) and Response Surface Methodology (RSM) because second order model or polynomial
equation was needed to fit for the response. The relationship between input and output parameters can be
visualized by 3D graphs which were developed from Mathematical modeling. Based on the experiment results,
the parameters that have significant effects on the laser power are current, laser beam size and water flow.
However, frequency does not have a significant factor in this study. |
