komputer murah: MASTERCAM 9.1

MASTERCAM 9.1 FULL VERSION

I recently finished converting my Smithy 1220 LTD to a CNC. I designed all the hardware from scratch,

as everything that I found available seemed inadequate for my needs. I design electronics

for a living, so it

was no big deal to me. However, I was totally unprepared for the world of CAM software. I use Mach3,

and although it comes with some nice wizards, they are a far cry from my needs. I finally selected

MasterCAM 9.1, as it is available to me, and is (despite its DOS-like appearance) an extremely capable

system (as you would expect for $20,000+, I think).

For those who have access to it, this article is a short introduction to how to use MasterCAM 9.x to

generate a workable G-code for the Mill. It mainly outlines the design process, and provides enough

background to allow the reader to experiment and learn its operation. I placed an emphasis on smaller

retrofit machines running controllers such as Mach3.

ADD FEATURES TO MODEL:

It may be necessary to add points etc, to make certain operations easier to define. For example, if

the corners were chamfered, it would be handy to have a point when translating model to origin.

RE-POSITION THE MODEL IN CARTESIAN SPACE (optional):

This can be done by either moving the model, or using the offsets. I prefer to move the entire

model.

Make sure that all the features are visible (LEVELS). From main menu use

XFORM/TRANSLATE/ALL/ENTITIES/DONE

The next menu will let you chose the translation method. I mostly use Rectang and Between pts

depending on what is needed.

If the model needs rotating use:

XFORM/ROTATE/ALL/ENTITIES/DONE

And then select about what point it is to be rotated, and the method of rotation. Make sure that

correct construction plane is selected, so the rotation will be in appropriate plane.
