Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? In this e-book, Greg Paulsen, Xometry’s Director of Applications Engineering, and Jason McClure, Xometry's VP of Manufacturing, share their decades of knowledge on machining tolerances, their importance, and offer best practice guidelines you can use when doing your CAD designs and drawings for your next project.
