I know this was addressed in BOB forum years ago.I tried to look it up on old forum to no avail,and my memory is being dumb,but heres the question:I am using a profile strategy,machining 4 open,contoured arcs.There is 5 step downs,with 3 passes to remove on each level.The problem is as it rapids back for each successive pass,the tool path violates the material.See pic.

That side roughing feature didnt support open shapes. You can add vertical and horizontal geometryto the ends of the arcs to make it do it without violating the part... V24 supports it.

I tried that,no worky for me.I ended up makin a pocket yo th intersecting corner and dashed the 2 lines and used HSP.Not fast strategy,because I cant control z feeds seperately in HSP.Can you show what you had in mind?Thanx.

i think the best way for me was to offset the geometry the amount of
stepover and the number of passes, then do a profile with no offset,
it would always honor the retract

[jrmach]

havnt tried that,hmmm

[jrmach]

Worked like a charm.Lot more work than shoult be,but hey I have oldd software.V-23.At least it can be done and time doing is well worth it because the tool path is the quickest by a long shot.Thanx Sir.

[dwood]

so you know it is fixed in v24, not a big deal in v23 if i remember to do this first

[jrmach]

not supported or fixed??lol
Thanx again

[BurrMan]

V23 side roughing didnt do open contours. V24 does.

[jrmach]

just trying to be funny BURR.but you are right.PS still want one of those little transportation devices I saw you had on BOB.When production start.Have you showed on this forum?Its awesome!

[BurrMan]

Hey jrmach,
Thanks. Yes I showed it here as a render. It was just an exercise, so it wont be produced... Thanks again.

[jrmach]
