The Water Cooler / Re: Metalworkingfun forum

rleete posted this on HMEM earlier today:

I just wanted to get the message out that the Metalworkingfun forum is done and probably will not be back.

This is due to the fact that the forum admin, and frequent poster Vinny has died. May he rest in peace."

Here's the link that he posted to the obit: https://www.lynchandsonsoxford.com/obituaries/Vincent-Vielhaber-Jr?obId=34185860

Nice job :-)

(And a reminder to me to get on with my aging grinder project)

Slightly rude of me that I've been a member on this group for ermmm...11 years, and yet this is my first post. In my defence, I had a lot going on in my life back in 2014/15 and lost a huge amount of enthusiasm for these things.
I recognise some names on here from other forums and the old uk.rec.models.engineering newsgroup, glad to see that some of you are still around.

Anyway, little project that I did last year. Posted the entire build story over on the HSM site but I thought I'd share it here too.
I have a surface grinder (J&S540) but needed to grind some cylindrical stuff, so made up this fixture that fits on the mag chuck.
It will take 9"/225mm between centres, with a centre height of just under 3"/75mm, and has a workspiece speed of around 260rpm.
The rear centre is spring loaded and moveable via a thumb lever, and the rear centre block has a flexure for taking out taper.
It was fun to design and make, and works very well.

Got to put this one on the back burner for a bit.

I have a bunch of stuff on order for it, but time just isn't there at the moment. I need to move my home office. I have an alcove in my work shop that I am going to wall in and turn into my office. That is going to take up my time for the next couple of months.

Glad to have you aboad Phil. As you know I too have been rather remiss in the attendance department.

So this (very cold!) morning I powered the beast up and confirmed that I could still initialise the turret, move all the axis and select tool positions but still with those same errors reported.

But objective today is to power up the old ToughBook lap top with Step5 (Siemens PLC support program) that runs under Windows XT.

A lot of faffing about and trawling through grey matter and eventually I got there - we are CONNECTED to the internal PLC that runs within the Siemens Sinumerik 820T control that controls this lathe.

A few screen shots just to prove it:

It reports the correct PLC type:

 


I can read internal parameters

 


I can see PLC Ladder Logic in real time

 


Now I need to go and warm up and refresh my memory of what is where in the PLC logic that's relevant to the current issue but my brain's a bit numb at the moment :)
