Backplot V 's Verify 5-axis Multi Surf

[DavidB]

Hi Guys I'm doing some mill turning programming using the Advance multi axis toolapth.

It's a Cam lobe shape on a Mori Seiki NT.

 

The part rotates with the chuck (C-axis) and the milling tool uses X,Y and Z axis.

 

What I'm finding using MC is that Backplot works as the machine does in that the work piece rotates. The pic below is MC backplot with the part rotating around C.

 

 

Now when I use MC verify the tool rotaes around the part and the part itself stays stanionary.

 

 

What this does is shows gouges that would not be there.

For example if you machine only 180 degrees of a component the tool then rapids to the other side of the part straight through the part.

What happends in backplot and the machine is the part rotates around 180 degrees with the C axis so the tool does not actualy go through the centre of the part.

 

I can not seem to get verify to act the same way as backplot or the machine.

 

Am I doing some thing wrong?

 

Thanks in advance.

Use Dummy Clearance planes and dummy tool calls and it should go away. Yes a PIA but welcome to the world of Mill Turns. Also if you are doing any milling for turning do not use lathe stock for it will not be seen by the lathe operations and give you some big fits especially if you want to stock transfer.

Thansk Ron, I found MC verify in this case to be a real bummer. I have never thought that about MC verify before.

 

Once I relised that verify was the problem and not my toolpaths I could move on. Just don't show the customer your toolpaths in MC verify
