Aluminum Bearing Block
« on: February 23, 2011, 07:56:44 AM »
The attached picture represents a bearing block made out from an aluminum flat bar 1” thick by 2”x 3” with four 1/4" mounting holes and one hole 1-1/16” in the center for the bearing.

My question here is that I see these red lines (are they called Rapids ?) appearing to be much higher than the aluminum piece.

Am I doing something wrong or it supposed to be like that?

Nicolas,

They will be related to your 'safe Z' setting either within Mach or the software you used to create the part.

Correct me if I'm wrong (don't have Mach3 installed here), but the SafeZ setting in Mach3 has nothing to do with the rapid height.
Rapid height is controlled by your CAM software.

So the rapids height is wrong as indicated?

No, not wrong, just more travel than you perhaps really need.

I don't know what program you are using, but for LC, see see Tutorial #6 in the manual.

Thanks RICH I was already there and now I can see that these red lines are the Rapid Heights. Since this subjects involves LC and I have more questions, I will start another post in the LC section of the forum.

I want to start some cutting with LC to familiarize myself with the techniques and then I plan to purchase a more dedicated CAM software
