GD&T in CNC Machining: Everything You Need to Know.

Why Does GD&T Matter in CNC Manufacturing? (autodesk) What is GD and T? Ask five machinists to interpret a drawing without it and you might end up with five completely different parts. That's because traditional linear dimensions and notes can only go so far, leaving plenty of room for misinterpretation. This is where GD&T (Geometric Dimensioning and Tolerancing), the universal language of engineers, is used to define how a part should truly function and fit. At its core, GD&T is a symbolic system tha......
