Not really sure what you are talking about there FastFarmer, the two contours that need to be merged are both open and do not overlap. Pretty much like two open brackets next to each other " [ [ "...

For what it's worth, Dolphin can cut this feature on a part mounted flat using the merge function. The part would need to be flipped to perform the same operation on the other side.
As per this...

Read up on the calculation of true feedrate during circular interpolation.
Here are several pages from the kennametal catalogue which explain it fairly well.
Have a read and see if you are...

Well done! I've often thought about doing something similar. Looks good

That sounds like a very sensible plan.
I have a full sized VMC that I started my own business with, but even now I still contemplate buying a Tormach since they offer a toolchanger.

Normally I...

You probably need to change the order of things. This would be the correct way to write what you have written.

My "Clarkson" corner rounding cutters look suitable for this purpose. Checking them with a radius gauge, I couldn't see any excess material.

I have a busy business doing CNC milling, so I can't comment specifically on your equipment, but if I were in your situation this is what I would consider doing:

The city I live in has quite a few...

Long ago I purchased 3 vices all in the same style as the cheaper vice you linked, but now I find myself regretting that none of them can be mounted on their side. Go for the one with ground sides!

The part you need is called a bush.
They are very common in a range of sizes, but the part you need has a 1mm wall thickness which is unusually thin. Most bushes are 2.5mm wall. I.E. a 25mm ID and...

Quoting the OP here "I have a bunch of wheel bearings that are 32mm ID".
The part you labelled "Hub" in the 3d drawing, does this item contain a bearing as your OP suggests?

Has this feature been implemented correctly in V11?

With such a low depth of cut I'm surprised you are having trouble, but 2500 rpm is unusually slow for a carbide cutter that size in aluminium so you might try upping the RPM to whatever maximum your...

How does the new simulation time work? Are we now able to input rapid rates & toolchange times to get accurate cycle times? Or does it just still only measure cutting time?

G09 = Exact stop check
G61 = Exact stop check mode
G61.1 = High-precision control mode
G62 = Automatic corner override

All of those will cause the machine to "pause" between moves.

G64 =...

Can we open our V10 files in V11?
Are there any other features in V11 not listed in the brochure you have sent via email?
Will remotely reprogramming the dongle disable it for use with V10?

Sounds like you are stuck in MDI mode.
Do you have a rotary switch with MDI, MEM, Tape, Handwheel etc on it?

Don't know about the 80's, but back in 2010 a guy in my city had the interlocks disabled on a horizontal cnc boring machine, can't remember the whole story but I think he spun a huge boring tool up...

txcncman said it best, I started out with a slightly bigger machine doing prototypes in aluminium, and what he said is what I did.
Lots of ER32 holders, a good set of drills, a few solid carbide...

I used to cut lots of PE foam with regular uncoated carbide bits.
Long series Garr endmills worked very well for me, however for a full 2 inch depth you will need to take two passes in Z for...

Chiming in with the DolphinCAM users.
I use it everyday for 2.5d and I love how easily I get correct, consistant toolpaths.
No 3d though, unless you count the "Merge" features and whatnot. These...

Worked in electronics for 7 years straight after dropping out of highschool. Bought a used CNC machining center off a guy going bust in Oct 2008 at age 24. Didn't have any experience in machining...

That is a very shallow helix for aluminium. The greater the angle the better the finish is the rule of thumb. Also that is a long overhang how that I can see it. Try using a three flute cutter (more...

I've never had a problem using uncoated carbide while cutting dry, using an air blast.
I know there are several coatings designed specifically for aluminium, perhaps if evacuating the chip doesn't...

I dry machine a fair amount of aluminium but I always use a strong jet of compressed air aimed at the cutter. I've been experimenting with misting raw ethanol too with good results. No fires yet!...

I can't help but notice aldepoalo's posting is just as invasive as BobCAD's sales calls. This thread was about SprutCAM in a Tormach forum. This thread is now about BobCAD. BobCAD was first mentioned...

Hi mate, I might be able to help. Send me an email (I'll send you a PM).

It doesnt sound like exactly the same issue, but sometimes I cannot select edges or faces after using sprut for a while and I have to go back to the "Model" tab and re select the imported file...

Well I can agree with this actually, as a user of SprutCAM 7 and Dolphin CAD/CAM. I started a part time CNC machining business and purchased Dolphin shortly after; as soon as I became full time I...

Hi guys, I have just recieved a drawing which has an external BSPT thread. I tried playing around with Dolphin's threadmilling cycle, but I can't seem to get the taper function to do anything. The...
