Very true. Besides that, not everything is automated... Yes, a lot of difficult, and standardized parts are CNC'd now-a-days, however, there are still applications where a unique, custom, only one to be made, parts still are required. A good example is creating a jig or fixture which will be used to secure a part in a CNC. It makes zero sense to spend time drawing, reviewing, coding, optimizing, etc, if all you need is one which suffices. Furthermore, as you mention, just because you stick your CAD drawing into SurfCAM and generate some tool paths and some M and G code, doesn't mean that it will work all the time, or even at all. One funny example we used to run into in school was that we would generate our paths and M&G code in CAM simulation software without taking the jigs/fixtures into account, and NUMEROUS times rookies would run a diamond tip bit through the custom jig which we fab'd, as well as the stock fixture in the HAAS CNCs, costing several 1000$ each time it would happen. Not only do you have to replace the bit and the fixtures, you need to check the spindle bearing and alignment, as it is almost always thrown off with an unexpected side load, completely defeating the purpose of machining on a CNC--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------EDIT: even when I go back and try add paragraphs it tells me to fuck off . This just started happening and I hate making walls of text
What velocity do you think a tool holder flying off a turret while hitting a chuck in rapid at 5000 rpm is going to be?
Faster than bullet proof glass can stop it
