The competition in the textile market has become more severe, and the export of foreign trade has become more and more inward. In view of the current certification of many textile products, many enterprises are hesitant. Customers can not make a few orders a year, and the costs of certification can not be earned. Is it necessary to do it? Yes, if we only consider the certified orders, there may not be such a large quantity for the time being. However, if we look at the issue of certification from another perspective, assuming that......

FSC and PEFC are both European initiated certification. However, PEFC requires stricter requirements. PEFC requires that wood and lumber are imported from abroad. For FSC certification, wood and lumber can be domestic manufacturers and forest farms that have obtained FSC certification qualification. The Difference Between PEFC and FSCFSC and PEFC are both European in......

The so-called reverse engineering technology is to 3D scan the physical prototype, data acquisition, through data processing, coordinate dimensional reconstruction, and other processes, to construct a three-dimensional model with the same shape and structure. Then, innovation is achieved by copying the prototype or redesigning it on the basis of the prototype. Therefore, reverse engineering is not a simple 3D scanning and copying process. The purpose of reverse engineering is to use physical objects to obtain point clouds and optimize and innovate designs based on point clouds. Of course......

Probe calibration is the basis to ensure the measurement accuracy, the main factors causing error in the process of probe correction are: the bending deformation of the probe, the position of the contact point when the probe is corrected, the measurement force, the touch speed and the detection distance, etc., the smaller the measuring force, the lower the accuracy, a certain measurement force and speed measurement should be selected for correction, and the appropriate detection distance should be selected to ensure the accuracy of the correction. CMM Probe Calibration Is Mai......
