"Weird Science" is perfect with "Blinded Me With Science" running a close second.
"It's poetry in motion"
Odd thing is that I only built this machine to build an invention of mine. I just couldn't afford getting multiple prototypes made. I made an aluminum melting furnace as well. I've always wanted a lathe, but needed something to pseudo mill my parts more. I'll buy an entire machine shop with the money I make from my invention.
Did the first operation of my part production. I cast a rough 3"X6" block of aluminum and machined one face flat using a 4mm end mill. It took forever at 20mm per minute. At least I think it was 20mm per minute. I used the F20 command and then G21 to convert to metric. So, did I go at 20mm per minute or 20 inches? It was pretty slow, so I'm guessing millimeters. I didn't pull out the ruler and stop watch, maybe next time. I need to get a bigger end mill if I ever do this again.
The machine performed better than I expected. There are obvious variations in the Z-axis, but the part wasn't clamped very tight and these are insignificant in the final part. It shows every swirl of the end mill's cuts, but feels quite smooth to the touch.
Had one interesting moment on the second lap around the perimeter. The rotozip lost its grip on the mill and it dug in gradually to a depth of about 3mm. I knew I shouldn't have gone in to watch T.V. I had to do it over two nights and turned off everything in between.
My question, is there a way to set each axis to a measurement? As an example, I turned everything off with X at 12.002mm, Y at 10.033mm and Z at 0.000mm. When I started up again X was 1.346 inches, Y was 0.954 inches and Z was 0.000 inches. I converted the inches to metric, but it wasn't even close. I had to move a lot of stuff around to get back where I wanted to be. It would have been much easier if I could have just set the numbers for each axis in turbocnc. Is there a way to do this?
I also found quite a few pores in the aluminum. I'm casting way too hot, throwing wet aluminum in the melt and letting the aluminum sit way too long. All the bad things for porosity. I'm suprised the pores were as small as they were. Time to turn the furnace down, dry my aluminum and get some chlorine. Anyway, here is a picture of the block.
