Process capability index Cpk measures how well a process output fits inside its specification limits, accounting for both the process mean (x̄) and its spread (σwithin). The formula is Cpk = min[(USL − x̄) / 3σwithin, (x̄ − LSL) / 3σwithin], and it only means...

A surface finish chart converts and cross-references roughness values (Ra, Rz, RMS, micro-inches, micrometers) so you can translate a drawing callout into a real, measurable surface. The tables that matter follow three references: ASME B46.1 for parameters and...

Machine D2 tool steel in the annealed condition whenever possible, then finish after hardening with CBN or ceramic tooling, or grinding, rather than trying to hog material out of an already-hardened blank. The single biggest failure mode is dwell: letting a tool ride...
