Several main functions of the image measuring instrument about the three-coordinate measuring machine

Several main functions of the image measuring machine about the coordinate measuring machine. These three coordinates mainly have several functions: detection function, reverse engineering. An effective tool for mold quality assurance: coordinate measuring machines are widely used in the mold industry. It is a modern intelligent tool for design development, testing and statistical analysis. It is also an effective tool to obtain unparalleled quality and technical support for mold products. The three coordinate measuring machines mainly used at present include bridge measuring machines, gantry measuring machines, horizontal arm measuring machines and portable measuring machines. The measurement method can be roughly divided into contact type and non-contact type. If there is a deviation between the mold cavity and the guide bushing guide sleeve, the deviation value can be found by the coordinate measuring machine for correction. After processing the cavity profile of the mold, the electric electrode on the electric pulse will form many inserts and partial curved surfaces. Therefore, the quality of the electrode processing and the non-standard surface quality become the key to solving the problem. Therefore, it is necessary to use a coordinate measuring machine to measure the electrode. shape. The coordinate measuring machine can use the input of 3D digital model, compare the positioning, the size of the mold completed with the digital mold, related geometric tolerances, curves and surfaces, and output graphic reports to intuitively and clearly reflect the quality of the mold, forming the completeness of the finished product Test report. In some cases, the mold has been used for a period of time and the wear has been corrected, but there is no original design data, that is, a digital model. The point cloud can be used to collect the point cloud, the output is compensated in the specified format, and the shape compensation is explored. Needle radius to achieve perfection, as an initial repair effect, when some surface contours are neither arc nor parabola, but some irregular surface, you can use cement or plaster to manually use it as the bottom embryo. Then use the coordinate measuring machine to measure the section line, feature line and parting line on each section, and output it in the specified format. In the modeling process, the shape and smooth curve of the probe radius compensation are used to design and manufacture a new mold.

Correct use plays a key role in its service life and accuracy. Please pay attention to the following points. 1. Before lifting the workpiece, return the probe to the coordinate origin to leave a larger space for the lifting position; 2. The workpiece should be lifted steadily, and no component of the CMM should be hit. Install the parts correctly and ensure that the isothermal requirements of the parts and the measuring machine are met before installation. 3. The image measuring instrument establishes a correct coordinate system to ensure that the coordinate system constructed meets the requirements of the drawing to ensure the accuracy of the measurement data.
