circle mill

[notso]

A quick question to try to extract some of the infinite wisdom available here.

 

Is there a way to adjust the entry and exit ramp moves separately when using circle mill? I want the tool path to begin in the center of my hole (to go with the pilot hole), ramp out to the geometry, interpolate around, then only ramp off alittle (not all the way back to the center). Having trouble w/ the end mill hitting the loose slug thats left over. I ended up manually adding a Z .1 move before ramp off to get around the problem this time. Luckily it was only about 20 holes! Any ideas would be greatly appreciated.

I use Contour Ramp. Select a 2d circle set type of cut to ramp.You can have different lead in and lead outs.

Not really. You have more control over entry exit using toolpath-contour-chain (or single)than with circle mill toolpath.

Other than this make a larger pilot hole

I just tried using using contour and then using "start holes" to get my pilot holes. tried it twice and both times it got about 90% through developing the tool path and then mcam crapped out on me. "Mcam9 has generated errors and will be closed by windows". has anyone else had this trouble?

Gotta head home now, I'll check back in the morn...

Thanks again

thanks, for the input. I messed with it a little more and by bumping up my tool path & data base allocations I got it to write the start hole tool path(only kills Mcam about 1/2 of the time). what kind of alocation #s should I try to use? I think my pc has 523,244 KB of RAM. Mcam is the only big program running on this machine(no Acad, Solid works etc.).

I forgot, I'm running Mcam 9.1 w/ solids

Set mcam to use around half your ram.
