FAI verifies that your CNC part, built using full production processes, meets drawing, CAD and purchase specs before mass manufacturing. Distinct from basic first-piece checks, FAI follows a structured workflow: reviewing requirements, producing a representative sample, capturing measurements, compiling an

Learn when tight tolerances are truly needed, how to specify them properly with GD&T and functional datums, and which design choices raise production risk.

Radial grooving cuts circumferential grooves on turned parts, covering both internal and external variants. It differs from face grooving and supports common uses such as O-ring seats, snap-ring slots and thread reliefs. Walk through its standard machining sequence, core design

Bevels are angled edge features widely used on CNC machined parts. Understand how they differ from radii and chamfers, and the correct way to specify them on engineering drawings. The piece walks through how bevels get machined, plus critical DFM

This lathe tooling guide covers cutting inserts, tool holders and boring bars for metal turning. It runs through tool types for external turning, facing, boring, grooving, threading and knurling, alongside tool materials. Follow a practical five-step selection workflow, grasp tool

Sinker EDM uses spark erosion to machine cavities in hard metals. This guide helps pick the process based on part geometry and tool access. It explores how sinker EDM forms cavities, why electrodes factor into part design, and when this
