    That part looks designed for molding or printing. The pin holes are fine. If you want to machine those axle holes you need to have radii in the corners for a small endmill. It's not going to be...

    That's why for a long time I would throw it away and buy whatever was cheapest on sale when it ran out of ink or dried up and stopped working. It was cheaper and more reliable than replacing the...

    I use spindle load limits and tool breakage detection, but I'm not using backup tools. I understand how to set usage limits, but I'm not running long enough batches to get the tool life data to...

    I believe there's an overpressure relief valve, that could be toggling. I have 1000PSI TSC, and when a small drill is in the work I'll hear a rhythmic thumping sound as it oscillates. Don't hear it...

    IMHO the best case is a shrink fit thru-coolant holder with 1000PSI TSC. When I'm not using the shrink fit I'll use an ER collet and run the TSC through the collet. Minimum stickout in both cases. ...

    STL files are for printing only. If you want anyone to look at your design you need to put up a CAD format. STEP, IGES, Parasolid, etc.

    I'd revise it to be reasonable, then sign it and return it. I've done this before and never had a complaint.

    "How close does it need to be?"

    "Make it right on."

    "I mean what kind of tolerance?"

    "Dead nuts".

    "Within .001" ok?"

    Anything tighter than +/- .001" is holding tenths. +/- .0001" is within a tenth. But if you really want to know capability you have to do a capability study.

    The B&S is faster and cheaper, and you already have it. Why replace it?

    Well I know it ain't Mastercam. The license manager doesn't work that way.

    Might could do it on a 4 axis VMC with some steady rests. Another important consideration, is how many of these do you need to make?

    I've been using the Lang system for about five years, no complaints. I don't stamp, I dovetail hard stock and do nothing for soft stock (it will imprint when you close the vise.) Love being able to...

    I use HSMAdvisor and the Helical Machining Advisor. Both give good numbers and have slightly different strengths and weaknesses.

    Probably due to chips falling into the spindle taper during toolchange.

    Edit:
    Make it a five axis with the spindle rotating in the YZ plane, so it can flip over and toolchange right side up, or...

    Depends on a ton of factors. Material and heat treat, diameter, depth, lot size, am I out of tool slots, is cycle time or process reliability more important?

    I have a 2015 VF-3SS with a TR-160Y trunnion that was bought new with the machine. The A axis (tilt) brake will occasionally, once every several months, start hissing when the machine starts up for...

    I find heat shrinks work great for 1/4" and up, ok of 3/16", and kinda sorta for 1/8". That tiny 1/8" bore has to heat up a lot to expand enough to get the tool in and out. So I have two long...

    The Haas will probably be happier with dynamic milling using a solid carbide endmill rather than slow full burial with large indexable cutters. I dynamic mill Ti and 17-4 with up to 1/2" solid...

    First, consider why you want to do this. If it's for the love of the endeavor, then more power to you. If it's to make money, well, it's kind of a flooded market; you'd better have an angle. Don't...
