복잡한 형상의 소재를 이송하기 위한 갠트리 로더 시스템과 지그 개발에 대한 연구

In manufacturing sites that process and produce parts in large quantities for the automotive and electronics industries, users require the reducing of costs and shortened delivery times. To meet these demands, an increase in the number of processes and an decrease in assembly times need to be addressed. Gantry loaders currently on the market in Korea are mostly used for processing lightweight and simple shapes and are not suitable for conveying and processing complex shapes such as automobile engines and aircraft parts. This makes it difficult to mount the material in place. This study aims to smoothen the transportation of complex shapes through the development of jigs and various approaches in the installation of the feed shaft by researching the gantry loader system for transporting multiple materials with complex shapes.

Owing to the excellent corrosion resistance of titanium alloys, they are widely used as materials for aircraft components. However, in terms of machining, dimensional deformation methods vary significantly, such as forging, owing to their difficult-to-cut property and the uncontrollable vibration generated during machining. A method to minimize the vibration generated during machining by applying advanced tools and controlling the sequence of machining processes, which can improve the machinability and precision of titanium alloy-forged low-angle components, is proposed herein. Using the proposed tool and based on a process order experiment, the efficiency of the machining process is verified by measuring the dimensional deformation of the low-angle component.

The model tested in this study was an automobile brake pedal pad that requires frequent replacement owing to the wear caused by repetitive loading. In the case of discontinued vehicles, parts supply was expected to be difficult; therefore, we reverse-engineered the existing brake pedal pad using 3D scanning and editing technology. Based on reverse engineering modeling, additive manufacturing was performed using TPU95A, a flexible material, in the FDM additive manufacturing process, and the dimensional characteristics of the initial reverse engineering model and additively manufactured parts were studied through 3D scanning and 3D dimensional measurements.
