I'm Mike Corliss and today I'm gonna show you how to square up a block.
We're going to start out with this piece of round stock.
And we're going to square up all four sides and then both ends so it's a square cube when we're done.
We'll be using a Tormach fly cutter to..
...mill the flats the sides, the ends.
And then a three eighths carbide end mill to true up the ends up to the sides.
I've just lowered it. I took 50 thou the first two cuts, 40 thou the third cut and now I'm going to take a 10 thou finish pass.
Now that we have one side flat we'll rotate that against the back jaw of the vise.
And then keep repeating that...
...until we have the other three side of the block cut...
...and squared up to each other.
Make sure you wipe the vice jaws and the vise bed off.
Any chips you leave in there you'll either crush them into your part...
or it'll cock the part if you set your parallels on them.
Took the 3/8" end mill and just cut a clean up pass across this end.
So now we have something to reference,
on the parallel on the bottom of the vise. And we know that this...
...cut will be square to the four sides we just milled.
And then we put the side that we just milled...
...put that to the back of the vise jaw down against the parallel.
Now that you have all four sides done just milled this end you got to break the edge on...
...these four sides with file.
When you put it back in...
...you put the same side against the back jaw.
It'd come out a little better, it should be really good anyway..
...but just consistency if you use the same edge against the back jaw.
Right now I'm just checking the squareness.
This one two three block should be pretty square.
If you hold it up against the the block we just machines you shouldn't have any...
...light between the part we cut and the 123 block.
And that's how we square up a block, all six sides.
