The effect of water is related to large waste, reduction in quality, and shelf life of these materials.
One analysis of this figure reveals that all processes occurred in the falling drying rate, i.e., there is no constant drying rate period for both types of materials studied, in accordance to several works reported in the literature [28-29].
As stated earlier, there was no constant drying rate period for both types of materials, and the in natura cassava cube reached equilibrium moisture content in a shorter time than the osmotically dehydrated cassava cube.

which components is the parts made of，how many is each component number, etc.), material information(ITEM, i.e. material attribute information, such as the name, code, coding, materials of each part, etc.）
，and manufacturing process information (PBOM, i.e., the arrangement of the parts process, used equipment, tooling, working hours and consumption of materials).The three kinds of information are the main content of data exchange ( integration) between the PDM and ERP, according to the above information，the ERP system arranges activities of the production and management in the enterprises, cooperates works between various departments in enterprises[1][2].
The tree of the product structure is composed of product assembly system diagram, product parts list ( including general parts, standard parts, self-made parts, outsourcing, outsourcing parts, raw materials )like a tree, each node of the tree represents each part or component, leaf nodes of the tree represent parts, each part or component has its attribute, such as the material, weight, size, color and how many componentsis is the part made of ?

Among the emerging technology for consolidating materials at high temperature at faster rates is microwave sintering technique.
However, only limited work has been conducted on investigating interaction between microwave and metal based materials.
Most of the work on heating and sintering was applied extensively for the processing of ceramic materials [6, 7].
Elsewhere, Y2O3 also has been incorporated into lightweight materials such as magnesium and magnesium alloys to achieve better properties [13, 14].

Moreover, the NC machining simulation will not have any accident, to enable students to relax the requirements of safe production, so when they are training to program and operate in the application of CNC machining simulation, they will tend to ignore the choice of cutting amount, such as cutting depth, spindle speed, feed rate, definition of blank material and tool path reasonable arrangements etc.
Although the simulation process full display machining process, but after all, just the simulation process, no workpiece materials, cutting tool rigidity and so on consideration, some cutting path in the simulation seem perfect, but in reality are hard to achieve.
