Building a geometrical model
Building a geometrical model is a final result of input data manipulation. The analysis of geometrical sizes, datum surfaces of the working peace should be analyzed and the path is to be designed. The whole way from workpiece to the detail consists of several steps (operations, speaking technologically). Each step includes changes in geometry of the workpiece. The workpiece becomes a detail only on the last step, with the last metal removing. Using modern methods of machining it is possible to create a geometrical model, and virtually follow all the changes of shape and size on each step. Based on this model a map of path sketches is created, were final measurements for each step are indicated (and are controlled by intermediate control). Feather on basing on solid body geometry model and using CAM-system technological operation and transactions are practiced, features of shaping and cutting toolsТ trajectories are determined- the modeling process is executed.
Writing the control programs
Modern technological processes are developed to be as well used on CNC machines. Control programs a especially important in multiaxial machining of complex shapes. Writing such program requires using necessary modules and libraries. While writing the program the cutting tool, cutting conditions and axial motion trajectory of the tool are finally determined. Besides its main purpose- controlling machining process, the control program allows to virtually model the whole machining process, verify your choice of cutting tool and estimate the cutting time. Intehservis specialists also can offer you a and-to-and design method for CAD/CAM which will provide full interconnection between work study and design documents and atomizes the creation of technological processes. The implementing of and operating on CAD/CAM systems is performed by highly-qualified Intehservis specialists, who had undergone special training in companies- developers of CAD/CAM systems.
Writing the postprocessors
To allow CNC system to understand the control program a postprocessor is required for each machine- it is a УtranslatorФ from CAD/CAM codes to a system code, readable for CNC machine. Writing a postprocessor is a difficult and time-consuming process. Each move and changing of state in machine sit is documented with a relevant code pair CAD/CAM- CNC.
