Theory of Constraints. Got it - I will examine this topic. Thanks, -r

MaxBreizh - this is the first I've heard about Poka-Yoke. I really like the example you cited. Simple and effective. I'm going to study the subject further, so thanks! Now, for the rest of the gang who's contributed so far. It wasn't my goal to initiate a "who runs the most difficult shop"...

Lean manufacturing is easy! There. I said it. I am not an expert in Lean, or any related theories or disciplines. I don't deny the benefit of Lean practices or Continuous Improvement. I'm just locked in the bitter barn when it comes to Lean because, in general, it just doesn't apply to my...

Hey CompositeGeek, or others - What systems (pen & paper / software) do you use to track you direct labor in a job shop? thx -Rob

Every surface is rough, as cast. The castings are delivered on the large side of the finished tolerance. The sanding merely being performed to get me parallel reference surfaces for work-holding in the mill. I'm not familiar with a double disc grinder. We have a grinder but are using the...

Hello - We've got a job for 5,000+ iron hinges, which we're machining from ductile iron castings. We've been belt sanding them, one at a time, to get a flat surface before the machining starts. This sanding is incredibly time consuming and costly. I'm not a machinist, but I understand we've...

My company has dealt with Uncle Sam for over 30 years. I would really recommend you get ahold of your mil-specs before you quote. If you bid an item, you're effectively agreeing to their requirements on that item. Langdon - is your firm ISO? do you have a MIL-I-45208 plan in place? Does...

Thanks to those who commented. Since the holes were already drilled on hundreds on these parts, I had no choice but to move ahead and hope for the best. It turned out alright. There was negligable deformation of the holes after bending, so the parts meet the customer requirements. -rob

I just want to put out a probe for any suggestions on a good versatile image viewer. Any suggestions? Off the top of my head, I can think of 4 different file formats which Uncle Sam seems to like using as a medium for digital drawings and specs: (1) .img (2) .c4 (3) .dwg (4) .cal I'm not...

Part of an assembly I'm working on is a curved/arc sheet. Per my design prints, there are three holes positioned at different angles of the arc. I'm sure that I could put the holes in after the sheets have been formed, but I have several to do, and it would be much more labor intensive...
