Re: [CAD_CAM_EDM_DRO] Re: toolpath creation problem or wrong interpretor setup?

As I said, Im new to all of this. So using Surfcam is a bit confusing considering they give you very vague documentation of all processes. But Im learning. And what I cant figure out.........Ive always got the great CAD_CAM_EDM_DRO group to steer me in the right direction.
I didnt realize that I should be doing the toolpaths in the minus Z and use the top of the part as Z0. DOH! Art brought this to my attention in the Master5 group, but Ive yet to try it.(Actually I didnt know that I could cut in minus Z, so I never thought of trying it)
Also Tim...
removing the G43,G49's worked flawessly. Thanks for the suggestions.
Thankfully I had enough sense to buy more than one of those endmills, so I have a few spares to break yet.
And ALan.....I had to draw the part in one orientation. I drew the toolpath offsets in 2d in Solidworks and imported the DXF into Surfcam for toolpath creation.probablt could have done it easier, but Im learning .
Maybe I'll figure it out sooner than later!
Regards,
Jim

Yeah, like the 7BA carbon steal tap (from England) I just broke! And I
was being nice to it! I'm milling the cylinder for a Stuart steam
engine. I decided to also mill a "practice" block (CNC comes in handy
for all those holes). It has "more conventional" threading. 5-40?
Right. I probably have a dozen each of the conventional 4-40, 6-32,
8-32 etc. taps, and I THOUGHT I had 5-40 taps and dies. Never found a
single one. Easy enough to pick up, but in a similar error, I also
THOUGHT I had a stockpile of 5-40 allen head cap screws. Oh well.

On the CNC, another thing that could get you in to trouble quick is
drawing the part in one orientation, and needing to have the "setup" in
another orientation. Also, having the drawing origin different then a
convenient point to "touch off" on the work piece.
