Hello all, Thanks for entering my thread. We are looking for a low cost cad/cam software for shop use. The software features we need, drafting, 3D machining, translators for .stp. .igs, parasolid. If possible, the ability to work with native Unigraphics and Catia files. It will also have to be...

Hello all, We have a GD&T postional tolerance call out that we need help with interpreting. The feature control frame uses 2 datums, and 1 of the 2 datums,(datum A), is the surface that the hole is on. My question is where do we get the second deviation from for the true position formula...

Hello all, I am looking for some tips on machining .250 thick AMS-DTL-22499 Comp 3 Type 2 Class 2. Dilling and milling this material without it delaminating has been a challenge,and waterjet is not an option for us. Any thoughts on the type of tooling, feeds and speeds, processes (helical...

Hello all, I need some help on dimensioning and inspecting a hole location with postional tolerance. Please see drawing. First is the proper use of GD&T, and if it is, how would we measure from datum B? I understand the concept of true position when the datums are all perpendicular to the...

Hello all, We are looking for recomendations on tooling for machining 6061, 7075, 2024 in the O condition. We have up to 24000 rpm available on a variety of CNC machines. We are currently using OSG Blizzards, and Onsrud single flute up cuts. Both work fine until we get into the O materials. Any...

Has anyone had any experience with Sarrett Altissimo, Mitutoyo QM, and the Trimos V+ electronic height gages? What are the pro's/ con's, user friendly? etc. Any input would be appreciated.

Is it ok to have 2 different positional tolerances on the same slot. If this is ok, how do you calculate the deviation without a cmm? See attached file. Thanks

Can true position be measured from 3 angular datums, and if so what is the formula. Please see attached drawing. Thanks.

Looking for some ideas on how to machine 6061 aluminum from .016 thick sheet down to .006. Suggestions on cutters, holding the material, any ideas at all. Thanks

Has anyone had any luck with dry machining 6000 and 7000 series aluminum. If so what types of tools are you using? What feeds and speeds etc.

Does anyone have any tips for the best way to machine LP410A nylon. We have cnc capabilities for the maching. What types of feeds and speeds, cut dry or with coolant, what type of coolant, how many flutes, etc.

Can you have a positional tolerance feature control frame on a hole without referance to any datums? If this is a correct way of dimensioning, then what is it controling? Perpindicularity, hole to hole, something else?

Has anyone had any experience with grinding Titanium. I need to remove material on some very thin 6al-4v. We have tried milling but we are tearing the corners. If you can grind it, is there a recommended wheel, grit , coolant,etc. Thanks all.

I am looking for some type of universal clamping mechanism that would allow me to hold extrusions for 3 and 4 axis machining. The extrutions are T shaped with different flange lengths. Some of the extrusions are not 90 degree which makes it a little more complicated to be universal. Any...

Looking for suggestions on tapping Delrin. I will need to tap a 1/4-20 through hole. The Delrin is 1.5 inches thick. I would prefer to do it in a CNC mill if that is possible. Information on the type of tap, coolant, or no coolant, cutting feeds, and speeds etc.

-------------------------------------------------------------------------------- I am having warping issues while machining .125" thick 2024-T3 alluminum. It is potato chipping as bad as 7075. I am removing .05". I started off with HSM contouring with a 3/8 dia. ball nose. 10000 RPM at 150 IPM...
