The illusive Boxford 260vmc

[Ricardoco]

Rick, i thought of you today as i removed a front panel from a boxford 240 lathe, all those lovely switches never to be used again......lol

lol Well mine will look nicer!!!! all those pretty buttons, when my friends come around how complicated will that look.... (anyone can operate a pc my friends think) but this looks like rocket science to them.... lol ......

boring... lol

lol.....a machine with flashing lights is illumination, nothing more.:surprised:
You see the point i'm making is, when i press cycle start and walk away i don't care how many lights are flashing, or tacho's are counting.:sad:

The machine is working, and the sweet music i hear, is metal being removed.lol

CNC does not mean "cuddle not cut":twisted:

Twang!!!! squeel!!! screach!!! i2i runs back to the machine, the expensive part in the machine has a big gouge out of it....Oh no...lol.


.....Somewhere else in the world Rick notices that the spindle is not spinning as fast as it should be, a quick glance at the g-code shows mach is trying to cut too much material in the first pass, on closer examination the cutter is lower in the holder than it should be, it wouldnt have mattered much anyhow as the little enhancement passes the spindle speed back to mach and this alters the cut rate so when he walked away the expensive part would have been safe.

CNC also does not mean "computerised not controllable"

However i can see this debate and its anacronims going on for some time..
so I just say "que sera sera"

Rick..

Rick, despite having a handheld tacho, you've made me feel I am missing something if I don't have one on the minilathe now! grrrrr lol

All those circuits using a PIC are fine but you note how there's never any source code to download or firmware to burn... so watch this space...

Well ive stated my reasons for wanting one and to be fair MACH does have the facility, However as i said mach says spindle go at 3000rpm, but there is no way of you knowing if the motor has obeyed this command, this could be a too higher feed rate lowering the spindle rpm, i just thought it would be nice for me to be able to see if the spindle was doing as it was told and maybe in the future incorperating a feature that lowered the feed rate to keep the rpm of the spindle at its desired speed, that is why i wanted feed rate control as well....

I WILL BE WATCHING, BE ASSURED OF THAT lol

Cheers George, the way i see it, even if i dont use the design it may be very usefull to other members should they wish to investigate the tacho question...thats what forums are about.. for a group of people to pool thair resources and help each other out to achieve similar goals and have a bit of a laugh and share friendships and experiences along the way.......so thats why i say "Im In!!"
