RE: [CAD_CAM_EDM_DRO] Re: CAD experiment entry

Tim,
Did I claim "my approach" was superior? That depends on what approach you mean:

If you are inferring that I claimed that my approach to the machining problem (i.e. using rectangular feed stock) was superior, I must not have written clearly enough because I was making no such claim. All I stated was that the approach merited due consideration, which includes a proper evaluation of the financial tradeoffs. It may indeed be the case that collet replacement (due to wear or due to accidental damage) might be more expensive that the time and materials saved using the square stock, but my point is that you don't know until you've done a proper quantified analysis. As for the 1-2 weeks of lost production, this is another thing you have to include in the consideration: how often does this actually occur, and is it better to suffer the downtime, or to suffer the carrying cost of keeping spares for critical parts in stock (vs. going with round stock and avoiding the difficult-to-replace critical part altogether).

If you are referring to my approach of not only "thinking outside the box" but also running with ideas so generated, then yes, I do feel this is a superior approach, and has nothing to do with idle conjecture.

Your exploits or mine over the last 6 years do nothing to change this.

In any case I think this has gone completely OT since (other than the odd reference to the original example) we are now fully into the realm of business management.

I'm not offended at all. I take a sort of smug inner satisfaction when someone I am arguing with tries flashing their credentials to support their argument. In this case all your experience really means is that you would have the input data for the comparative analysis at your fingertips in your specific situation, whereas I would have to spend days digging up the information and making additional assumptions or additional alternatives to the analysis.

[...]So the first time you crash out a collet [...] you have to make [...] a new custom collet. Now you have lost 1 - 2 weeks of production. [...]

I have gone from nothing to owning my own 7000 sq ft industrial building, 2 Haas machines, a 120 watt laser, a 3D laser scanner, a 3D printer, and a $100,000 plus inventory in 6 years through a major recession.

What has your approach gotten you in the past 6 years? If you have accomplished more I will consider your approach more seriously.

Now I hope you are not offended, but I am speaking from real world knowledge and risking everything I own. You seem to be making idle conjecture and then saying your approach is superior.
