@RotarySMP

2 ай бұрын

If your Dovetail height is 11mm, you will need the TCMT16's. The TCMT 11 are about 9.5mm high. It has been pointed out that by moving the cutting edge so far forward of the plane through the center (4.4mm), my cutter will actually cut a slight radius on the dovetail face. I was trying to ensure I had enough clearance to prevent rubbing on the rear edge. I screwed up and made it 4.4mm instead of the intended 2mm. Probably not relevant in this static use case, but if you need to meachine a sliding way, keep the cutting edge closer to the center line. The 7° clearance angle on TCMT means you could probably get away with on CL, as long as your cutter diameter is above about 30mm.

I`ve been watching Stefan`s videos for quite a while, and those compound slides by Schau that he worked on are also made in a stupid way in regards to oil grooves... To be precise, the grooves are made in such a way that they leave a high spot over time in a section, which then galls the rest of the slide should you actuate it towards the more extreme ends of the travel...

Have u checked the dovetail angle after cutting it? If the TCMT11 insert's cutting blade plane is on the rotation axis the insert will rub on the dovetail that is being cut in the upper part, but the dovetail angle will be correct. To prevent rubbing the insert is better placed half its thickness above that plane (it's center plane then contains the rotation axis), but this affects the cutting envelope and subsequently the resulting dovetail angle, so the insert needs to be rotated in its seat to compensate.. it's a bit tricky.

Since I monetised my channel, I can't use the hobby license of Fusion, but dont generate anywhere near enough revenue to justify a commerical license. I have a 20 year seat of FeatureCam. Not the most productive tool paths, but it is a hobby, and I am patient.

1:26 Chris might have the lead in the graphics but I prefer your sound effects! Btw is there any chance I could reach out to Franz regarding the Prvomajska? We have a similar, possibly a gen older mill at the university in not so good condition and I am trying to make it usable again. Insights from the pro would be very much appreciated.

Hi Micheal. I have some nato rail bolted like that, but had a light mounted on it. I really need to redo the who lighting and camera mount set up around the mill, as it is a bit of a PITA.

So was that angle now right or not? Or will the be the cliffhanger for next episode?

Question: Why not drill the screw hole all the way through? Granted, I know you'll be the only one using it and *probably* not leaving it lying around with no anvil or screw in it. I just worked a place where we had to machine many of our own parts and features for old machines, and *someone* would always lose anvils for the tool holders, so swapping between a LH RH Center he'd take the anvil off another one, leave it on the carriage, then pack it full of chips (we had to machine metal, epoxy resin, other non-ferrous materials that make nasty dust that cements when wet/oiled). So many of our tooling bars we wasted time picking clean that we eventually through drilled them all. This also let us use any length screw since the different holders sometimes had a screw 1mm different and well, you guessed it, if he was losing anvils he was losing screws and then F@#$king the next guy over because the inserts wouldn't actually be clamped tight.

Yeah ... That cutter will not cut a real straight angle. It might look 60 degree but it will be somewhat bowed because of that huge off center cutting flutes. If the cutting edges are straight on a rotating tool they need to be on center, if you need them to be off center for whatever reason then they need to be set at a compound angle or helical. It's just maths ... But nice try. You could still salvage it I guess

I'd have loved to watch MotoGP, but ServusTV stopped broadcasting in Germany, so F'in Sky TV of all scumbag companies scooped up the exclusive rights to broadcast MotoGP in Germany, meaning I also can't just go to ServusTVs streaming site, since that just tells me it's not available in my country. So I guess I'll just watch the highlights this season since I'm not about to burn 30€ a month on Sky just to watch a few hours on a few weekends. Screw 'em.
