Building Modular Setups
Using Stevens Setup Components to build a fixture involves the same basic steps that are used to design conventional fixturing. Setups can be designed (1) on CAD, (2) in a setup staging area, or (3) at the machine.
STEP 1 - DETERMINE WORKPIECE LOCATING DATUMS
6 independent locating points required to fully constrain workpiece in x, y, and z. On many workpieces, it is convenient to categorize locating points into:
  1. Primary (3 datums defining a plane).
  2. Secondary (2 datums oriented perpendicularly to primary plane).
  3. Tertiary (1 datum oriented perpendicularly to both primary and secondary location.)
STEP 2 - SELECT MODULAR LOCATING COMPONENTS
To eliminate indicating or probing requirements, use the built-in accuracy of the qualified surfaces and bushing locations of Stevens Setup Components.
STEP 3 - SELECT CLAMPING COMPONENTS
Clamps should directly oppose locators. Check for spindle tooling clearances when positioning clamps.
