Process chain for producing 3- to 5-axis workpieces

The production process chain generally starts with workpiece design. The data generated at this
stage provides the basis for further processing and, ultimately, for production.

Production
Creating a CAD model
Use of the CAM-internal strategies and methods to
generate the individual machining steps and calculate
the paths.
Simulation of the calculated tool paths with collision
checking.
Generation of the NC code in the postprocessor.
Generally, the path at the tool tip (TTP) is output in NC
code.
Data transfer of the NC programs and setting up of the
tool and workpiece. If required, creation of a main
program that calls the generated geometry programs.
Specification of the high-speed settings, e.g. in
CYCLE832, if this is not already taken into account by the
postprocessor. These are tolerance, compressor, path
control, smoothing, jerk and velocity.
Manufacture of the workpiece on the machine.
