“…2. First, a tool ball (TB 1 ) is attached to the tool nose with as short a tool length as possible and adjusted to be coaxial with the spindle axis using a DBB [16]. Here, the tool length refers to the length between the tool center point (TCP) and the tool ball center.…”

In this study, parallelism errors between the spindle axis and the linear axis of machine tools were measured using a double ball-bar. Specifically, two circular tests were performed to measure the parallelism errors using tool balls with different tool lengths and a workpiece ball fixed to a workpiece table. Parallelism errors were calculated by analyzing, simultaneously, the measured double ball-bar (DBB) data from the circular tests. The proposed method provides accurate measurements due to a large offset between the circular tests within the working space of machine tools. Additionally, the approach only requires a DBB and adjustment/extension fixtures; thus, it simplifies measurements and is cost-effective.

“…There are many investigators have carried out error modeling research for complicated machinery system using MBS [41,23,44,39], mainly focus on designing and constructing a model to determine geometric error of machine tool and developing the key technique for compensation-identifying geometric error parameters. [43,17,4,7,22,2,11] introduce the methods of geometric error compensation, thermal error modeling, position error compensation, position-independent geometric errors modeling, volumetric error modeling and sensitivity analysis and establishing a product of exponential(POE) model for geometric error integration.…”

Location errors are considered as one class of the fundamental errors of five-axis machine tools. For the improvement of machining accuracy, it is important to propose an efficient and accurate identification method of location errors. This paper uses a touch-trigger probe and a testpiece to identify location errors of a five-axis machine tool with a tilting head. All the measuring procedures are performed based on the single setup of measuring equipment. A model-based decoupling algorithm of squareness errors of linear and rotary axes is proposed. Then, a new probing procedure is proposed based on this algorithm to increase the moving distances of linear axes without additionally auxiliary equipment. This basic idea can also be expanded to other machine configurations, for instances, the one with a tilting-rotary table which is also illustrated. The experimental results demonstrate that this method is efficient and accurate.
