- [Instructor] Every CNC machine is different.
Machines are different sizes.
They might have different numbers of axes,
or they may only use a subset of G-codes.
In order to accommodate the wide variety
of machines available, Solidworks CAM lets
you define the type of machine you're using,
and customize how the CAM tool paths
you generate are turned into CNC G-code.
Let's take a look at the machine definition options
by pulling up the Define Machine dialog box.
By default, Solidworks CAM comes
with the three axis mill defined.
If you're using Solidworks CAM Standard,
this is the only option you'll have.
Make sure that the mill is selected.
Now let's take a look at the post processor.
In order to accommodate the wide variety
of machines available, most CAD software
will generate a machine independent toolpath
called a cutter list.
That cutter list is then translated into the actual motions
that your machine will make in order to cut the part.
That translation step is called post-processing,
and in order to know how to translate the cutting list
into the actual G-codes that your machine will use,
we need a file that acts as a translator.
When you're ready to generate the G-code,
you need to post-process the generic cutter list.
Typically, you'll get a tool post processor file
from your machine manufacturer,
and then you can upload that file into Solidworks.
Solidworks can then use that file
to convert the generic cutter list
into the actual G-codes for your specific machine.
Not all manufacturers have tool post processor files
available for their machines,
but many third parties do make them for free or for sale.
You can usually find a post processor file for your machine
by either Googling or contacting the manufacturer
of the machine itself.
