The demand of measuring the internal topography of holes with submillimeter diameter and high aspect ratio is increasing. However, moving a coordinate measuring machine (CMM) probe tip into a submillimeter hole manually is extremely difficult because the diameters of the probe tip and the hole are extremely small to be seen clearly with human eyes. An automatic measuring method and system is presented in this study to simplify the operation and improve the measuring efficiency. A micro CMM system was built. Two cameras were used to image the probe tip and the holes to be measured. The obtained images were magnified, and the edges of the probe tip and the holes were extracted. The image coordinates of the center points of the probe tip and the hole were obtained. The center coordinate values of the probe tip and the hole in the world coordinate system were achieved using the principle of binocular stereo vision. The probe tip was moved into the holes by the differences in the obtained coordinate values. Experiments were conducted. The effectiveness of the proposed method and system was verified by moving the probe tip into a hole with 1 mm diameter. This method can be used to assist in the measurement of deep submillimeter holes, especially in nonbatch measurement situations.

“…A few commercially available retrofit systems require the addition of dedicated controllers and interfaces and lack standardisation and flexibility. Most of the other developments in this field have been directed towards enhancing the capabilities of CNC-controlled CMMs [ 1,2]. A microprocessor-based system was developed for 2D tracing and measurement using a touchtrigger probe retrofit on an NC milling machine functioning as a CNC-controlled CMM [3].…”

This paper presents a sculptured surface recognition and localization strategy for the inspection process using the CMM. First, the database is generated from the CAD data based on the Z-Layer concept. Then, the three-dimensional shape of the object on the CMM table is constructed using a vision guided CMM. Two vision cameras are implemented to guide the CMM to the object, and B-spline interpolation method is applied to generate a surface that passes through the obtained data points. As a following step, the Z-Iayers of the generated surface are created and the geometric properties are calculated to determine the best matching surface in the database. Rough location and orientation of the object are determined by analyzing the image data, and the minimization algorithm is applied as a next step to obtain more accurate localization results. The experimental results show that the proposed method can be applied effectively for sculptured surface recognition and localization in the inspection processes.
