Kit: Yes, we have been in this debate more than a few times now. If nothing else, I have learned to summarize the whole debate clearly in just 5 lines. <G>
When I was in the Helicopter industry, I was part of a major shift from hand done drawings to 3D, solid modelled parts. What was interesting is that the amount of design work and effort actually increased, because we had MORE PRECISE CONTROL over the most minute details in the parts. While the assembly time decreased, other aspects of part production, like inspection, increased. We actually worked harder and longer to make batter parts, and, we had to be real careful about managing our data. Ultimately, the results were worth it. We achieved levels of fit and finish that were staggering, and, we improved the quality of our product by a great degree.
I generally spend at least 20-40 hours of computer time on a folder design before I even cut a part. That's what it takes to verify the design, double check the design, write the programs and make the tooling. Now, I'm not getting paid for that time. I'm counting on being paid over time, which assumes that my customers will buy the knife and I'll get to make more than just a few. The benefit for me is that the parts fit together consistently, and, thus I am able to focus on those operations that I am not doing by CNC.
My productivity has NOT quadrupled by the use of CNC and other sophisticated equipment. BUT MY QUALITY AND CONSISTENCY HAS!
And, I can INNOVATE, which keeps me motivated and my customers happy.
I recently invested in tumbling equipment that will enable me to vastly improve my finish on S30V, which is a bear to finish out at the higher Rc levels that I prefer. Although the tumblers require no input from me other than loading/unloading parts (apparently a timesaver), I actually have to hand finish the blades to a finer and more uniform finish than I would if I weren't tumbling them. So, I'm using technology AND working longer and harder because of it. Why?
BECAUSE THE QUALITY OF MY FINISHED PRODUCT IS HIGHER.
And, that's the truth...
