Hi Art
I was chatting with Chip and this may be a clue as to what is going on in LT the stock is called out at 15.1910 and the finish is 13.150 but when the code is processed in mach in the first lines of  of code there is an X move of 8.5 MM in Radii this makes the stock now at 19 MM so the program is picking up an additional 4.2 or so MM with everything at zero why is this happening ?

How much you leave on the stock will depend on the clearance setting.. and the depth per pass. The amount left will typically be less than one pass depth and at a minimum the clearance setting..

RC,
 Interestingly, woke up this morning, looked into the mirror,  and I'm now a caveman. Lazyturn.....even a CAVEMAN can use it!

Not sure if it's a XP sp 2 or 3 issue as four computers here and they all do something a little different. When I get a chance, will try three more computers when i get over a friends. Also don't over set your refresh rate if your fooling around with the display settings as the screen may be blank when you boot up and it's a PITA to fix. I am quessing that it's an individual's computer. As long as none of the input fields go away it's tolerable. Sooner or later i'll find, tie-up, torture, .......and ever so slowly modify the little Krelin.

Hi, Art, Dennis

It looks as if it's not liking the 0.5 value.
Hears a test dxf and some pic's and a tap file.

Chip

Edit: .49 drop's a pass left side at Arrow, .48 pick's it back up, Both sides of the part are the same dia. "10" unit's from X zero. ?

Hi Dennis

Try this one with a .48 per pass value rough and LCam Turn final pass.

Hi Art
LT seams to have an issue with the cut per pass if i cut .5 MM it leaves 4.20 of stock on the profile but if you set the cut per pass less then that LT will leave less stock is it something i am doing wrong?

Dennis
Can you show me a screenshot of the rough request and the result?

Hi, Art

I've been working with Dennis about these issue's and Posted a dxf that isn't so long to show it clearer, 4 post's up, sorry to butt in.

In the Pic's: I used 5 for pullout to get it out of the way, 0 stock clerance to highlite the issue.

Pic 1, original stock size used, rough 0.5, should have very little blue showing.

Pic 2, original stock size used, rough 0.49, should have very little blue showing on the larger dia..

Pic 3, original stock size used, rough 0.48, almost no blue showing.

Pic 4, stock size inc. to 15 or larger, rough 0.5, drops rough pass at Arrow.

Thanks, Chip

Hi Guys:

 Still dont think I see the issue.. All 3 photo's seem to be correct for the depths commanded.

  The lines outside the darker blue of the stock are of course the pullouts.. and how close the other lines get to the stock is a function of if it woudl hit going in another "depth" distance..

 Since this is roughing, it will not make a closer pass, it simply goes in at .49 or .5 or whatever.. if .5 takes it so far it hits the profile, then that pass wont be made at that position..

Hi, Art

There are more issues hear, This part is dead on 10 unit's  even all over, In these 2 Pic's there seem to be Issues.

Thanks, Chip
