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 tools’ 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 “translator”
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.
