Abstract

Operating high-power lasers are very hazardous to the health and safety of the workers. In addition, positioning a sample material during laser operation is very dangerous. Thus this paper will report the design and fabrication of Controlled Motorized Stages (CMS). The stages consist of two mechanical parts; an x-axis high-precision translational stage and a rotational stage. There are three main parts of CMS that are mechanical system, electronic interfacing and motor driving circuit, and control system. The mechanical systems were design and fabricated using a lightweight aluminum with high-precision resolution. They were drive by a stepper motor that can drive up to 1.0 kg sample on the stage. The electronic circuit was interfaced to microcomputer. In order to control the stepby- step motion of the stages, a program was developed with the aid of Visual Basic 6.0. The result shows that the x-axis stage can move in a range of 90.0 mm with resolution of 26 μm in step-by-step mode, and speed exceeding 0.2 mm/s when operating continuously. In the other hand, the rotational stage can move 7.2° per step angle.
