The wear failure mode of a paver spiral blade was simulated by EDEM software. High-manganese steel, medium chromium alloy and high steel were selected as matrix materials; SiC particles WC surface particle reinforcement the prepared EPC process. performance mechanism analyzed microstructure, hardness, impact, pin disk, erosion test, morphology. Modeling with software applying discrete element a...
Casting has many process variations depending upon the material, the type of pattern, mould and the pouring technique like sand casting, investment casting, die casting, squeeze casting and lost foam casting. Sand casting is the most widely used process which can be used to produce intricate parts in almost every metal that can be melted. Casting defects analysis is process of finding the root ...
a water–soluble gelatin combined with polyethylene microspheres were developed to prepare alumina composite foam. gelatin was used as the gelling agent and polyethylene was used as pore making template. on the other hand, kaolin was used to provide green strength and cuo was applied to decrease the required temperature as a sinter aid. alumina bodies need elevate temperature for sintering, incr...
Since the early 1980s, CAPP has been expected to bridge the gap between CAD and CAM. Though numerous research works on CAPP have been reported, it is not easy to ®nd a commercial CAPP system applicable to complicated objects with freeform shapes such as mold and die. The dependency on CAM system is holding one leg of CAPP, while the complexity of the solution space in freeform shape machining h...
