Abstract
This article presents an approach to investigate the variation propagation of machine tools due to the geometric errors produced in assembly process and determine a pre-adjustment method in assembl...
Highlights
The rapid development of the manufacturing industry has accelerated the ever-increasing demands for high precision and reliable machine centers.[1]
The principal sources of errors affecting the machine accuracy are classified as geometric and kinematic errors caused by thermal distortions, stiffness errors related to the cutting forces, and other sources.[3,4,5]
Among all the error sources, geometric and kinematic errors have the highest influence on the machining quality because they impart a direct effect on the relative position between the cutting tool and work piece.[6]
Summary
The rapid development of the manufacturing industry has accelerated the ever-increasing demands for high precision and reliable machine centers.[1]. The variation propagation in the assembly process should be modeled to predict the final errors and the adjustment of the components should be determined before being assembled to improve the final machine accuracy.
