Cutting force is the major factor which causes machine tool geometric error, for the sake of finding the relationship between cutting force and the machine tool geometric error, this paper established a model to simulate and analysis, Mastered the situation of stress distribution of various points on the machine and the regularity of internal stress and strain distribution; designed experiments for the precise measurement, and obtained the actual data of machine geometric error. the data matches the results of the simulative analysis. the results has a certain referential value to optimize the design of machine tool, the geometric error modeling and make the realization of software compensation, etc. |
