Basically, Mastercam has stages it goes through from the actual CAD to the final stage of having an NC program
1- CAD model on screen ( can be wireframe ( lines, arcs etc), surfaces or solid models.
2- a machine definition file is usually pre-defined ( this sets available axes that can be used, the post for this machine, and control for this machine ). Try the "Machine Type" pull-down, you may have one set-up already
3- create toolpaths applicable to the machine that you have selected that utilise the data in #1. ( eg you define a 3-axis machine, but you cannot program a 4 or 5 axis operation ).
4- When posting , mastercam uses the toolpath operation into an NCI file, which in turn is converted to NC-code using your assigned post The Post
is a .PST file that is specifically configured to your machine, it can be customised to some extent by yourself ( can be daunting to the average user, as special care is needed, miss a comma, $, etc may stuff it good and proper )
If you do not have a post, try the generic posts and select the one with closest outputs for your machine ( this would normally be the one to customise.
Customised posts can be obtained through your mastercam reseller. Not sure on $$$, 3 axis may be less than 1000 Communications to & from M/C
the NC-file would reside in your PC, another software package would need to be set-up to enable communications with the machine.
many would use floppies or USB to get the NC-file into the machine, until a comm link is set-up
I suggest you have a seperate directory, other than the c:/mcamx/mill/nc directory to place the finalise NC-file in that is to go machining in case of overposting, or the operator stuffing up editing on the machine. |
