Fast Assessment of Machine Tool Errors Using a Touch Probe and Cube Array Artifact
터치프로브와 Cube Artifact를 이용한 공작기계 오차의 신속한 규명
Abstract
In this paper, a methodology to assess machine tool errors quickly is suggested using a touch probe and a cube array artifact. Parameterized error models derived are expressed of model coefficient vectors and backlash errors to be determined. To determine the unknown model coefficient vectors, a cube array artifact is proposed. Considering CMM measurement data of cube vertex coordinates. error vectors for all axes ate obtained and used to complete the error model. Some simulation results show that the suggested error model can follow the true values within 10
