Fixture plates are for parts that need a dedicated setup but don't justify a custom tombstone. The part must have at least one flat face for seating — the generator orients it face-down and projects a conforming pocket from the bottom profile. Grid holes on a 25.0 mm pitch accept standard modular clamps. Four corner holes mount the plate to the machine table.
If the part fits in a 6″ vise, soft jaws are faster to machine and easier to store. If you need quick-change capability across multiple parts, zero-point plates add pull-stud registration. Fixture plates fill the gap: irregular geometry, second-op work, or parts too large for jaw stock.
Generated from real STEP files in the stress test suite. Plate dimensions, pocket method, and grid hole count vary with part geometry.

No Z-aligned flat face for fixture seating. Parts without a planar bottom cannot use fixture plates. See Soft Jaws for alternative workholding.
