Oh, Forgot to add: DUH!!!

Wow, it's the simple stuff eh? Nothing like a little feature to make ya scratch yer head, I've been running full speed for a while now, and never encountered it, must have changed my selection by accident and lo, had to get humble. Thanks for the wake up.

Yep, Gnom moves but geo doesn't. Also having the slow issues described in the other thread. Just visited this I am going to roll back and see if it fixes it, Ditto what crazy said, "Thank you Microsoft"

All of a sudden, no work, anyone else have this happen? M/C 2018 Dell XPS 8500, 24g ram, NVidia GeForce GT650 Win 10 Home

Use "computer" for all cutting, rough and finish, I use "wear" for any tight tolerance feature, ie: mating part, tooling fit, hole / bore sizing.

had it running over 180 before, machine got real jerky, 2005 vintage. I'm actually jealous of Ron, 400 just has a good ring to it.

Nice work! You have that animal running real smooth. I would be interested to see what the machine settings and MC parameters are.

Cool stuff Ron, Thanks for passing the info along! Still running my 7.5 hp minimill at 120ipm in 4340, 1/2 dia, 5 flute SGS, 1.0 deep, I suppose if I dropped from 20% stepover to 10% stepover, I could probably get it to run over 200. Whaddya think?

Quite possibly a recreated, duplicated, redundant copy of a certain troll, but the troll started at X2! Bob, I use the "reference point" almost exclusively, I simply use it at the last operation before I know I will rotate the 4th ax, thus keeping all of the ops for each part down in the cut as close as possible, including using incremental retract and feed planes to keep it even closer. I have saved a ton of time doing it this way.

This PARALELL SAMPLE.MCX-7

How about requiring a user to log changes into the Verisurf add-in notepad tab, date, time, changes and reason for change. The "part note" area will stay with the part file, while the "note" area will stay with M/C regardless of file opened, including closing and reopening M/C Small thinking, but maybe small enough to chase down the offending party, and create some projected accountability.

Stop by the shop, I have a hard copy

Surface finish shallow, use edge curves created from the solid pocket edges for containment.

Stand it up and use a .130 Thurston slitting saw or equivalent to mill it after milling the profile of the outside of the fins, use an extended arbor to get all the slots in 1 op. If you have to stay laying down, maybe try to select all the fins and go with a simple contour with depth cuts, and step down by depth, then take a finish pass on the walls, it would create a lot less code. Made a few heatsinks before, these are two of the techniques we used.

I didn't mean to kill this thread! To the OP, What did you end up getting the part done with? Tool? Toolpath?

7500 might be a little too hot for the 3/4tool (1472 sfm) I threw this together, I have used this method in 4340 at 45Rc with success. 350-400 sfm is about all your going to get away with, that is, with an altin or equivalent coating. TRY THIS.MCX-7

Ditto!! I have changed many of my constant use programs over to Opti and dynamic, the savings are fantastic, and, the hidden bonuses are slowly coming to fruition. The reduction of finishing toolpaths and the complete elimination of tools for subsequent ops are just a couple of the "un-obvious" features. Cycle time, both in roughing and finishing ops has been slashed, up to 70% in many cases. Haas Mini-mill? 7 1/2 HP. 120. ipm, in 4340? dry? Just wish it had some more RPM! Thank you for the work you have put into these toolpaths, and the overall improvements that have been made! 35 yrs in this trade, 20 of it with Mastercam, and I still get excited watching a cool program run, Opti and dynamic are cool! "D"

End mill would be last choice, the center is loading up and pushing the thing all over, the holes will not be predictable or on size. The circuit board drill is the best option here. They are cheap and deadly accurate, even without a centerdrill or spotdrill.

Well then, come by the shop and sniff some coolant with us!! We'll get you fixed right up, chips and noise included. Ya gotta get out now and then, you know what happens when you stay at the keyboard too long!

Happy New year, How is the job going?

Brandon, FWIW, I run a 1/2" endmill, .70 - .90 deep at 550 sfm and .04 step over (8%) on a minimill in 4340, (4200 rpm @ 90.00 ipm) I have removed an average of 105 lbs. of stock before the tool needs changing out. I would assume that a $50.00 solid carbide endmill, vs. a $180.00 solid carbide (3/4) endmill would be a no brainer for an old school guy, and the cost of 5 endmills would be a lot cheaper than many hours on the machine. I cannot view the file as I am away from my M/C computer, so, I don't know what the part looks like, but, I do know that a "Dynamic" toolpath, with a 1/2 endmill might just save you a ton of time and the boss a heck of a lot of money, Crazy would know the S and F's for the Ti, as I do not run a lot of it, but I would bet his #'s would yield some good results. Good Luck

M/C settings for comm were set improperly, I will give the specifics when I get to the shop this am. In other words "PEBCAK" D

Got it figured out,,,,,,,,,,,,,,,,,,,, Thanks for looking

Having some troubles with a new system and sending files, it worked good for a few days, now it sends the file on the screen, but doesn't load it into the control. I don't think it is a M/C problem, but, is it something someone else has run up against with Win8? TIA Darrell MCX7MU1 Mill level 3 Lathe Solids Dell XPS 8700 I5 24g ram 2g vid 2t HDD WIN8

Getting the solids option will be money well spent, er, invested. I have built entire assemblies with it, made all of my tooling with it, including 4th axis tooling, vises, plates, etc. Being able to view the part inside of the raw stock, on the "machine" has been a valuable resource, and now, with fill holes and other new features that I have yet to use , it has just gotten better.
