길이가 긴 소재 가공을 위한 고속가공기 설계

Abstract

In this study, we design a high-speed machining machine that can simultaneously process the top and sidesurfaces of a material with a length of 8 m. The high-speed machine is modeled such that it can preciselyprocess two pieces of material (length = 8 m; weight = 10,000 kg) on a table. Stress, which is a designresource, is determined using an S-N curve(Stress Number of cycles to failure) based on a safety factor ofthree, and displacement is determined by applying a first-class control tolerance of 0.5 mm. Structuralanalysis is performed by applying the weights of the structure bed, table, column, and girder using software. Based on the result of the structural analysis of the high-speed machine, the displacement of the spindle andtable is 0.1282 mm, which satisfies the target displacement of 0.17 mm, and the maximum stress of thestructure was 15.8 MPa, and the safety factor was 13.3, which was very safe.
