영문 초록

A laser cutting M/C is designed for the precise fabrications in the machine recently. The cutter is a gantry type one with specified functions of movability and strength in order to satisfy the workability. The gantry frame should move with a certain velocity in a relatively short time for the proper cutting of the object materials. The gantry is fitted with rack and pinion and the acceleration field is formed by actuating this rack and pinion. The relative displacement should be within the allowable design criteria to make sure the precise cutting of the materials by the laser. In this paper, modal and structural analysis for a laser cutter which is commonly used in the fabrication of machine, is carried out to check the design criteria or the system. The system is modeled by placing the proper shell and solid finite elements and fictitious mass properties to represent the real one.
