PRIMARY PROCESS SELECTION AND PROCESS SEQUENCING AS THE PART OF PROCESS PLANNING
The field of our research is defining the main criteria for selection of primary processes and types of operations in production. Selection of primary process is based on nature of material, quantity, form complexity of the part, part size/mass and some other factors. Type and sequence operation are results of influence different factors as product shape, surface roughness and tolerance. In application will be used some aspects of knowledge base. Application will enable users to better understand procedure of selection primary process and sequence operations with possible additional technological gradation support. Self learning and testing of students is included in application. In application are used IT technologies of Visual Basic.NET.
PROCESS PLANNING APPLICATION AND INTERNET CONNECTION
This work is a part of the project creating the technological database necessary for improvement of process planning and connection database through SQL server by Internet environment. Developed web site for Database System and Process Planning is useful especially during development student’s project’s of technological process inside fields Process Planning, Production and Operations Management. Here we have elaborated the first phase of selecting tool machines, tools, operations and initial material on the basis of the chosen criteria.We have indicated the problems of selection and the possibility of working out a solution. The Internet technology gives us the possibility to share our data with many users and a chance to improve the elements of Virtual Manufacturing
SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
