green machine update!

Hi. I've watched your video and it is neat. Certainly new to me. Glad you have your motor balanced. You are attuned to this work and a pleasure to see the advancements.

What did I do this weekend? I am glad you asked. Non-circular boring anyone? (I am such a nerd)

Pretty slick. I often think of going CNC, but *computer* I work at a computer all day, and the last thing I want in my shop is another blasted piece of electronics or computers to fool with. My sole concesion is use of a DRO, so I turn cranks, and it does what I need. Still, very cool what those machines can do.

I understand. I like the motion control/computer interface aspect of this. (I work IT)

Watched a nyccnc outtakes video showing them crashing their renshaw probes. Painful to watch! Looks like you have a pretty nice setup. I wish I had the space for all those machines!

Welcome to the group!

In your video, there's confusion in terminology. The mention of the word tolerance when the word clearance would be appropriate.
Tolerance is the amount a size can vary from nominal and still be acceptable. An example might be a given size, say .2500", with an assigned tolerance of ±.0002". That designation has nothing to do with how much clearance is assigned to a mating part. It just assures that it will be acceptable. The amount of clearance is determined by proper dimensioning (along with the appropriate tolerance).

The issue you faced is a less than acceptable mismatch in sizes, which could have been controlled by tolerance, although proper dimensioning of both components would be required. The tighter the tolerance, the less chance of a mismatch, assuming the mating parts have been dimensioned properly.

My purpose in making this comment is not to lessen the value of your video. It is to reinforce the fact that the word tolerance is commonly misused, and is misleading. There's a whole community of people talking about tolerance when it has little to do with the problems being addressed.

Correct terminology is something that few seem to give much weight. That doesn't apply just to machining, of course. I frequently have to decide whether it's worth the effort to explain the difference between accuracy and precision.

"tolerance" and this has nothing to do with any members on the board here.....just a few people I know... tolerance is the ability to be able to put up with someone who claims that they know what they are doing, and brag about it, when in fact they have no idea what they are doing

[whateg0]

That sounds like another forum I know about! One that I spend very little time on because of it

Actual boring - painfully slow as I was being very conservative...
