|Thread: Vectric Vcarve upgrade to 10.5|
This Vectric thread milling video came up in my suggestions whilst browsing the tube.
|Thread: Any body with experience of CNC PLC Controllers DDCSV 1.1 2.1 3.1 RMHV 2.1|
If you already have a suitable RaspberryPi then PlanetCNC could work for you.
I use a Windows & PlanetCNC setup and I have no complaints at all with it. I feel it would be a more flexible solution than a DDCSV, but of course you'd still need a monitor & keyboard.
|Thread: Myford S7 Cutting Barrel Shaped Cylinders|
No, they're OK milled as long as the cutter's sharp and you get a clean finish you'll be fine. Infact you're better off milling the sliding part anyway as it's easier to scrape because the surface isn't as skiddy under the scraper.
Provided your saddle isn't too worn, it's perfectly possible to skim the worn face.
To keep it simple you should try to maintain the current 'step' measurement between the sliding (worn) face and that face which the apron is bolted to. This is to ensure minimal misalignment with the rack and leadscrew.
If your 'step' measurement is currently 0.5" from face to face and you skim off 0.008", then you also remove the same amount from the saddle mounting face too. The same goes for the rear of the saddle, where its gib strip locates.
Once machined, a lick with the scraper would assure a better fit.
|Thread: Coronavirus, advice from ME|
Only when I saw on their web page: "They have determined that several features have now changed; in particular, more information is available about mortality rates (low overall)". I thought they were saying overall mortality rates were low.
You can rest assured that, like you, I'll stop trying to understand what words mean and instead trust the word of polititians and the likes of Neil Ferguson and base my future on it.
Sorry if I interrupted the simple language you must be listening to on the daily news.
Am I missing something here?
How can a gov decide to reduce the fundamental threat status of Covid-19 (months ago!) while it's still claiming and acting as if we're in deep danger from it?
That link is to a government website and amongst other things states that: "As of 19 March 2020, COVID-19 is no longer considered to be a high consequence infectious disease (HCID) in the UK."... and ..."They have determined that several features have now changed; in particular, more information is available about mortality rates (low overall)".
They're the gov's own words, so where's the conspiracy theory there?
Keeping the country on lockdown for months despite this hugely downgraded 'threat' makes no sense to me unless something else is going on.
If I'm misunderstanding something then I think they need to make their message clearer for people like me.
Do you have a link I could look at?
Here's some advice from me: Read this government web page.
|Thread: Part breakout /fixturing|
You could cut right through, but leave a few small & thin holding tabs to keep the part in place.
The next stage would be to generate a toolpath that cuts away those tabs, but before running the code, apply some hot-melt glue in the already cut areas to provide support whilst the tabs are cut.
So similar to you own idea except no need to grind the the other side to release the part.
|Thread: Old School Drawing Exercises and 2D CAD|
Drawn with three arcs and it's not too far out, using SODs clue about the 1.5" arc.
Edited By blowlamp on 03/07/2020 16:16:09
My best guess for the centre location of the 1.5" rad arc is at about 2.5" to the right & 1.5" down from the top/left corner. I'm suspecting a 0.625" rad arc at the top and a 3.125" rad arc at the bottom to join all three together tangentially.
Easy in CAD whichever way you do it.
|Thread: Exploding Grinding Wheel|
Has it really bumped off that many, or does that number include those that died with Corona virus rather than of it, or Corona related, or Corona suspected, or any other thing that is designed to make you think it's a Covid-19 death?
El Thicko could also be seen as those that are taken in by what they see on TV and read in the press and aren't interested in alternative views and opinions.
Sexist Comment: "These blokes never admit their ignorant macho posturing provoked a mate into taking stupid shortcuts".
|Thread: Free or inexpensive 2D cad for clock wheels|
Gearotic would be ideal for a clockmaker like yourself, but unfortunately it is $120 USD.
|Thread: Mill unexpectedly cutting crooked|
The cutter helix could provide the pulling force, but there would need to be some slack somewhere or inadequate grip of the workpiece to give the movement.
Maybe bowed vise jaws or a slighlty barrel-shaped workpiece would allow the part to pivot up at its pinch-point in the jaws. Loose vise jaws, even?
It sounds like the workpiece is lifting as it's being cut, if I'm seeing the problem correctly.
|Thread: Coronavirus, advice from ME|
I don't get ME, but I still want to know what's been said!!
Was it something Podiatry related?
|Thread: ER32 frustration|
Does the nut screw on OK without a collet?
|Thread: fusion 360 cam|
Ecam does a similar job to Fusion 360 using its Contour strategy. You can either define a stock model of the desired shape or use a ready-defined block adjusted to your own dimensions.
Whilst not a 3D system, it is fairly straightforward to use and it doesn't have the learning curve of Fusion 360 either.
Unlike Fusion 360, Ecam isn't free, except at the weekend (Sat/Sun), but this might well be enough for some people regardless.
Demo video I did with Ecam's solution.
|Thread: 2mm endmill help|
If you can get some good dimensions of your collet, I could CNC one up for you to try if you think yours is slack.
Just let me know if you want one doing.
