Aiming at the disadvantage of the existed algorithm, an efficient remachining tool path generation method for pocket with island is proposed in this paper. Firstly the pocket and island boundary curve recognition method is described in detail, and then the machinable and remachining region recognition method is presented. Moreover the tool path generation method is introduced. Finally the validity...
The pilot-scale experiment is done to speed up the pace of industrial application. The results show that the whole set of devices runs smoothly, the process for pilot-scale experiment is reasonable, the desulfurization rate can be above 92% for long time, the rate of leaching Mn2+ can be over 80%;The product of MnSO4 can arrive the fertilizer level(GB1622-86) and feed level (GB5252-876).
Now the compound surface is applied broadly in the industry production design. So the tool path planning closely related to compound surface numerical control (NC) machining needed to studied in depth. In this paper, a novel cutter location (CL) point fitting method in the phase of post-process is proposed. In the calculation process, the first the initial cutter location points are calculated applying...
As an important component of the CNC milling machine, the stiffness and vibratory modal of spindle need to be analyzed in the process of design. In this paper, the above two performance parameters were analyzed by use of finite element method (FEM). For stiffness analysis model, the beam elements (BEAM4) and spring-damper elements (COMBIN14) were used. For modal analysis, the solid elements (SOLID45)...
A surface reconstruction method based on generalized regression neural net (GRNN) is presented. First, in order to eliminate noise points, some sample points are chosen from the measured data to construct GRNN. Thus a neural net to approximate the measured points is obtained. And the distribution probability of the approximation error is figured out. In result, the noise points are eliminated when...
