The use of machining centers in the manufacturing industry plays an important role to meet market demands for products with complex external geometries. Based on this role, machining center performance needs to be maintained in the best condition. One of the main indicators of machining center performance is the level of accuracy. The accuracy of machine tools can be affected by geometric errors that occur in machine tool components, such as in motion guidance systems. Geometric errors on the components of the motion guide system will be translated into geometric errors on the workpiece during the machining process. Standardized geometric specification tests, such as ISO 10791-2: 2001 can be utilized to check the machining center geometric specifications. Geometric specifications that do not conform the standards need to be followed up with corrective actions. In this research, the straightness motion error correction procedures of the X-axis of vertical machining center is formulated. The correction procedures are formulated based on data modeling derived from research by Holub et al., 2015. The data modeling produces a saddle surface profile where the linear guideways are mounted. The hand-scraping process is used to correct the unevenness of the surface profile. VMC 500 machine is selected to implement the correction procedure. Proposed correction procedure consist of Health, Safety, and Environment (HSE) guidelines, recommendations for the number and qualifications of workers, recommendations for equipment and materials, and corrective actions for motion alignment errors from the X-axis.
