    I've had great results with Helical brand cutters in 17-4 H900 and Ti6Al4V. 5 hour life dynamic milling with a 1/2" 7-flute at recommended parameters. I've occasionally used them on harder...

    If you want a serious answer, look at Harvey Tool. They specialize in small cutters in standard and special geometries.

    I wrote a serial macro a number of years ago that would scale, put the numbers in a line at an angle, or an on arc, and optionally project that on a cylinder. Used NCPlot to debug.

    On my TR-160Y trunnion in the VF-3 I use a Lang Quickpoint plate with a Makro-Grip 77, an ER-40 collet fixture, or a custom tombstone fixture I made. The vise and collet block can also go on a...

    What's the dollar value of the time spent questioning and justifying a $10 purchase, including the delays waiting for emails to be read and responded to? Bet it's a lot more than $10.

    Last I checked Citizens are still really limited on memory size, still measured in meters of tape. Have they fixed that yet? How's Tsugami in that regard?

    When I want a super good finish on a top face in Ti I'll use the exact same parameters and cutter as if I were dynamic milling at full depth, but with a minimum cleanup for depth. The MRR isn't...

    Order them resin printed from 3dhubs.com. Choose a tough resin. I recommend only ordering two or thee to start and check your fits. For the axles you might want to make most of the X profile a...

    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.

    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.
