1.   Natural state material (No Hardening)
    a.   Allows for easy machining of tooling to fit parts.

2.   Limited Clamping
    a.   As long as cycle time or production numbers do not require a
          fast clamp sequence, the number of manual clamps should be
          limited.

3.   Limited Doweling or “Shimmability”
    a.   Precise location of tooling components is not required, nor is
          the ability to shim certain dimensions to print.

4.   Manual Operations
    a.   T-Pins / Hinge bases / vise grips may be used if warranted.
    b.   Fixture Speed does not require other methods.

5.   Operator Dependent Failsafing
    a.   Can you trust your associates to accurately and consistently
          load a fixture?
