Fixture

Also called workholding, soft jaws, holding fixture

This entry has not been translated yet and is shown in English.

A device that locates and clamps work in a repeatable position and does not guide the tool. Every CNC operation needs one; its whole job is making part number fifty land on the same datum as part number one. Rigidity here, not a better cutter, is what actually stops chatter.

A two-column text comparison headed "Whether the tool is guided". Left, in accent: Fixture — locates and clamps; its job is making part fifty land on the same datum as part one, and rigidity here is what stops chatter. Right: Jig — guides the cutting tool through a bushing or against an edge. If it guides nothing, it was never a jig.
