They are, in most cases, the most cost-effective solution for handling bulk material mass flows over short and medium conveying distances.
The optimal design of belt conveyor should take into consideration the influence of variables, such as idler roll diameter and spacing, belt speed, cover properties, and bulk material properties.

The Workpiece Material Information.Metal parts is the main object of numerical control processing, such as all kinds of steel, aluminum alloy used in military enterprise accounts for a high proportion, high strength steel, titanium alloy, magnesium alloy, high temperature alloy also have a certain proportion, and the physical properties of the workpiece material will be focused on in the process of machining.In the dynamic simulation optimization of workpiece material identification of milling force coefficient correctly or not directly influences the accuracy of the simulation results.Cutting force coefficient considering the properties of cutting tool and workpiece material, cutting tool geometry, card loading condition such as main factors.Comprehensive consideration of the complexity of the model and the calculation precision, the average cutting force coefficient model [3].Experiments show that for the precision of the conventional material average coefficient of cutting force model
Fig.5 Dynoware raw data graphics It has completed five categories and more than 90 kinds of materials of the milling force test and parameter identification of materials, the milling force coefficient has been inputting CNC milling cutting database.
