When
choosing the appropriate method for manufacturing a CNC part it is possible to
either program the machining path as ‘part
program’ using the conversational language and input co-ortinates manually
or it is possible to use the ‘CAD CAM’
method of drawing the component shape on a 2d package, and then selecting
parameters before exporting the program to the machine.

 

Identify
the benefits and limitations of each approach and draw valid supported
conclusions. You may use your experience of operating the machine to support
your written work.

Your
written work should include comments on the following;

An evaluation of your own effectiveness
in using the two systems of manufacture. (summarise your experience of
both methods)

 

Factors to be considered might include
how easy it was to learn the software packages, ease of programme editing
and the lead times needed to produce the components.

 

Evaluate your discussions with a
manufacturing engineer who works for a company using both systems or which
has moved from CNC part programming to an integrated CAD/CAM setup could
be used as further evidence. (Use your work experience or arrange a
‘factory visit’ to gather some evidence)

 

When
discussing the programming methods topics that should be included are:-

Control over the sequence of machining
operations for both roughing and finishing operations
The control of grouping of similar
operations (drilling of holes, pocket cycles)
Tooling considerations and the selection
of tools for operations.

(Speeds / feeds, types of tooling to be used
for specific machining operations)

Inspection of parts during programming /
after manufacture editing of program(simulation, proving, modification)
User interface (ease of programming,
flexibility, ability to edit programs)
Post-processing (transfer of files/data
between computer and machine)

 

Importing geometry files (dxf / stl) to
reduce time to manufacture from other CAD packages
