For most machinists or carpenters, as long as you’re not building medical equipment there’s maybe twice in your professional life that you need a level of precision that justifies the extra expense. For everyone else, for 99.99% of the time, it’s “measure with a micrometer, mark with chalk, cut with an axe”.
