CAXA-WEDM is a powerful, easy-to-learn and easy-to-use wire-cutting processing CAM/CAD software. It can be widely used in the processing of complex mold parts and other precision parts. The automatic programming process generally has the following steps: The workpiece graphics are computerized. 2 wire trace generation and machining simulation. 3 generation line cutting plus engineering
- Magnesia cement uses in masonry construction is ancient. It was used primarily as a mortar component and stabilizer for soil bricks. Magnesia has also been identified in the Great Wall of China and other ancient landmarks. Roman cement is reported to have contained high levels of magnesia.
- In the West,Portland cement replaced magnesia for masonry uses in the 20th century when energy was cheap (see energy efficiency) and mold infection was poorly understood.
- However, some projects continued to use magnesia. New York City's Brooklyn Bridge base is made from locally mined cement, a mixture of calcium oxide and magnesia cement commonly called Rosendale cement, the only natural non-fired cement made in the US.
- Magnesia cement boards were approved for construction use in the US around 2003.
- Due to its fire resistance and safety ratings, New York and New Jersey were early adopters of magnesia cement board manufactured by Dragon Board in early 2010. Florida has adopted magnesia boards for mold/mildew resistance. Innova Eco Building System obtained the first approvals for structural uses of a magnesium board structural insulated panel. The magnesia board panels are load bearing, hurricane and impact tested magnesia cement structural insulated panels, obtaining a Miami Dade NOA certification for the high velocity hurricane wind zones of Florida, +180 mph winds.]].
- Located in Taipei, Taiwan, magnesia board can be found on all 101 stories of Taipei 101, currently the eighth tallest building in the world. Magnesia sheeting was used on the inside and outside of all the walls, fireproofing beams and as the sub-floor sheathing.
