My solution is to use a tension compression head with a torque limiting collet. I have to do this anyway, rather than true rigid tapping, as my spindle can't be fitted with an encoder (rather like a Bridgeport, there's no easy way to do this on my turret mill). Instead, the spindle speed and downfee...

So, to clarify, does the Fusion post processor output G84 with F or Q for the thread pitch? It looked as if most Fusion posts including Centroid set the spindle speed and then convert the pitch into a downfeed, F. Uwe talked about creating a modified post to take advantage of Centroid's G84 that all...

Yes, I checked back through previous NC files generated in Fusion and no matter what settings you choose, it uses F, not Q. There's even a check box in the Fusion PP for "use feed per rev" but this still outputs G84 with F. My machine doesn't have spindle positioning, so I have a tension c...

I've generated rigid tapping from Fusion no problem. I'm away from my machine right now but could it be that you need to select "use canned cycles" or similar within Fusion CAM?

You shouldn't need to edit the PP to get this working. I'll see how I did this later when I get back....

Thanks. I've seen that thread. I think it might answer my question but just to be clear: it doesn't matter that the motor has a small gear on it and the spindle shaft is larger. As long as I have a 1:1 ratio from the spindle shaft to the encoder, the ratio of motor:encoder is irrelevant, correct? T...

It's not recommended to put large capacitors (total 200nF in this example) across the output of an opamp. In the case of the LM4324, that max recommended value seems to be around 100pF and certainly below 500pF (where the phase margin becomes zero). It's not going to be possible to define how the de...

The CAM integration is great, and I'm not stuck with a several hundred dollar bill annually. What CAM are you using with SW? At one point they were giving HSM Works 2.5D for free with SW but then HSM was acquired by Autodesk and it now forms the CAM elements of Fusion and Inventor. I'd assumed the ...

How to use M101 - this is from the lathe manual but I assume it's valid for mill too:

Those marks are suspiciously evenly placed, which perhaps suggests they are due to a spec of swarf or metallic particle. If so, they may be built up rather than worn away (ie convex rather than concave). Take a closer look and also use a sharp blade to determine which it is. You may well find they c...

As stated airblast / mist / flood aren't adequate on deep cuts up to 3 x cutter diameter. (Not to mention the unwanted mess of high pressure airblast.) Almost all of my cutter breakages have been due to inadequate clearing of chips, resulting in recutting / welding. The choice seemed to me to be be...
