I would use a horizontal mill with the part set up in V-blocks but you haven't said what equipment you have access to. You need to elaborate if you want relevant information.
This sound's like you are way overthinking it. Drill a hole, use a reamer, press in a real dowel pin. Probably will decrease the cost of your casting removing that boss if you haven't had molds made yet. If the chamfer being that big is really mandatory then some mild or stainless pins could be...
Sounds like these guys haven't used Talon grip jaws. No prep, all the ease of any vise setup and I promise you won't lose a part holding on to 0.06-0.08. It's the way I would go for sure. Check out the versa grip for any irregular stuff you need to hold also, they work great on waterjet parts.
You may want to consider a custom grind from them. They have a nice tool builder on their website for submitting quotes. The Gorilla mill name hasn't been around super long but they just came up with that name for marketing purposes. The main grinding company that they are is Carbide Grinding...

Gorilla Mill has off the shelf tools for this application. I've used a bunch of their tools in the past and the performance is incredible. Try these guys out and I doubt you'll look for anything else.
The newer ones don't have an umbrella tool changer. It rides with the spindle and it only needs to go home in y to grab a tool. Machine can sneak behind the wall when home in Y to do a "pallet change". I've never seen one in person but I've had a fancy for one for quite a fey years. It's also...
This type of post gets flamed all the time here. You have not given us enough information to even guess what the problem is. Do you have any alarms? I see it says 640M so it's a mill but people like to know what machine it is. Is it not showing up in the control or just won't run when you press...
What you are looking for is a parameter to control if it returns to the R plane or the Initial plane. I have a manual here for Smooth Control but I think for this parameter it should be the same. The parameter is E104. For face machining units it is bit 1, For line units it is bit 2. You want...

Just get Fireball's other vise. Friend of mine has one and the build quality is pretty nice. Maybe not as...
I'm not familiar with the machine you are using personally but I would be very surprised if you had more than an inch between your soft and hard limit. Can you possibly make your main or sub jaws longer? a little of both? If you want to give it a try though maybe you could override the parameter...
Spent the last 5-1/2 years at a job shop that only uses Mazatrol. We have turret lathes with Milling and Y axis, a few verticals, two Horizontals and a Variaxis true 5 axis. We do all our programming on the floor. Almost all of our customer base cannot provide 3D models for their parts. Mostly...
I haven't used the smooth AI programming but I have used the 3D assist that is just below it and something I feel needs clearly started is that it does not add functionality to conversational programming. It only streamlines the process. At the shop I worked at we were only conversational and I...
The customer surely doesn't need the tolerance they ask for but sometimes they are willing to pay for it. Such is definately the case for the parts I've been referring to. The 0.2494 +/- 0.0002 holes are for pess fit of 1/4" dowel pins and the parts hold razor blades for an industrial potato...
