Abstract Multi-scale casting parts are important components of high-end equipment used in the aerospace, automobile manufacturing, shipbuilding, and other industries. Residual features such as parting lines pouring risers that inevitably appear during process random size, morphology, distribution. The traditional manual processing method has disadvantages low efficiency, high labor intensity, h...

To solve the problem of water pressure fluctuation caused by the traditional double-acting intensifier, the paper has designed abrasive water-jet cutting machine based on phased intensifier as well as open numerical control system. The structure of cutting machine as well as the hardware structure and working principle of phased intensifier are introduced. The phased intensifier employs a const...
