Would not hurt to put a small oil hole in the center of the rocker arm, from the roller side to the rocker pin hole. Include a small chamfer on the both sides to let oil collect and get distributed. Might even add one for the cup. There are more forces there than you might imagine. Then again, I can't imagine you running it for hours. Damn thing is cute.

My understanding is a true random tool changer uses a swap method.

You would have to have a Tool change arm to swap tools and then a master log file to keep track of the tool pockets and which tool was in what pocket.

not worth it, unless you have lots of tools and tool holders, and want a rotary delivery system. I think I seen Peter Homann has a rotary carousel on his mill, but I believe it puts back the tool used and indexes to the next needed tool.

So for the rest of us, can they be converted to dxf files?

This still does not make sense to me how you get defection in X or Y for a hole your drilling in Z if you have good drilling practices.

But whatever, I was always use a center drills first to get true position, then start will smaller drills and work up to the hole size I need. Using a pecking cycle helps also.

As far as a multiplier, you could change the multiplier to a variable like a b c (which is an axis your not using) and just change the value of that. So you would have f(x)=x-(y-y*c)
Now, just put .99 in the C axis DRO or enter in your code a G0C0.99.(don't forget to change back to G1 if need be, or you learn some new lessons) Later in the program I guess you could change it to some other value like C0.88. It's not a good practice and quite obscure & convoluted, but have fun and be safe.

This might work for you, or a variation of such depending on the offset you need.

Function Cfg's
Formula
don't forget to enable formulas

f(x)=x-(y-y*.99)
f(y)=y+(x-x*1)

Looks like it works but I did not do a full test to prove it out.

VB and the development of wizards / Re: key cutting

How about a standard house door key? How do we determine the code/trick? Is there a position to depth secret code. I would assume that it is different for each key company manufacturer.

But I would think knowing the number of pins and the distance between them is a starting point. Then measure from a reference point to determine the differences/heights. Then it's a matter of mapping out the transitions and filling in the boxes.

Now, I would think using a formula would work for that.

Thou it still comes down to what John, Rush & Rich refer too.

I'd have to say... don't fudge, fix!
