The connecting rod is a critical part inside the marine engine. The inspection of its important parameters is directly related to the assembly and quality of the marine engine. A coordinate measuring machine (CMM) is a conventional choice to measure the parameters of a connecting rod. However, CMM requires significant resources in time and cost, which leads researchers into in-situ measurement. This article presents a fast and in-situ measuring method by using a laser-based measuring head. Two measuring strategies are adopted in the inspection process. For positional measurements (such as the hole–center distance), whose accuracy requirement is generally low, the coordinate system of the numerical control (NC) machine is combined with the measuring head to acquire the positional parameters. For dimensional measurements (such as inner diameters), whose accuracy requirement is rather high, the NC machine is used just as transportation. Note that the measuring head has the ability to perform the dimension inspection independently. The accuracy of the measuring head is high enough to meet the dimensional accuracy requirements. Experiments are performed to validate the proposed method. The measuring error of the inner diameters is from 5 μm to 7 μm. The measuring error of hole–center distance is within 15 μm. The measurement of all these parameters can be done within 1 min.

“…The reason for this could be the manufacturing accuracy of the two rotating axis components and the assembly clearance between them. The reason for this also could be that during the long-term operation of the machine tool, the A-axis was geometrically displaced due to uncertainty factors such as the weight of machine itself and the inertia of workpiece under high-speed motions [33]. Displacements indirectly affected the position error of the C-axis.…”

“…For the first time, an automatic error calibration scheme was adapted by Ibaraki [32], which used the trigger probe installed on the spindle of the machine tool to measure the space position of four standard blocks which were clamped on the C-axis worktable, and then the geometric error of the rotary axis was calibrated. Jiang [33] proposed a location error identification method using a touch-trigger probe and a test-piece on a five-axis machine tool with a tilting head. In their nature, all of these methods involve the contact detection of block standard parts.…”

This paper presents the design of a precise "ball-column" device to efficiently and accurately measure the geometric error terms of both rotary axes of the five-axis machine tool. A geometric error measurement method of spherical contact was proposed based on the influence of the geometric error term from a five-axis machine tool rotating axis on the integrated geometric error of the machine tool. A multiple degree of freedom, step-by-step contact method based on on-machine measure for measuring the spherical center point is proposed, and the solution formula of each geometric error term of the rotating axis is established, respectively. This method can identify 12 geometric errors based on the influence of one rotating axis on another rotating axis after long term operation. The spatial error field of the five-axis machine tool was constructed by analyzing the error law of the two rotating axes of machine tools based on various positions and postures. Finally, after the comparison of the experiment, the results showed that the accuracy of the developed error measurement device reached 91.8% and the detection time was as short as 30-40 min.

“…Ibaraki et al [12][13] presented a pyramidshaped machining test, and the test proposed by Velenosi et al [14] was analogous. Ibaraki et al [15] and Jiang et al [16] presented a simpler set of machining tests based on the same principle. Morimoto et al [17] presented a machining test based on a non-rotating tool.…”
