Adjustable fixture

A fixture for supporting a workpiece during a machining operation, the fixture comprising:

• a housing including a plurality of walls defining a cavity;
• a lateral clamp disposed within the cavity;
• and
• a plurality of pins disposed within the cavity, the plurality of pins comprising at least three fixed length pins and a plurality of adjustable length pins, wherein the adjustable length pins are locked at a height in accordance with a bottom surface of the workpiece when the lateral clamp imparts a lateral force on the plurality of adjustable length pins.

A fixturing device for securing a workpiece in place during a machining operation, the fixturing device comprising:

• a housing comprising a plurality of sidewalls and a bottom wall cooperating to define a cavity, wherein top edge portions of the plurality of sidewalls cooperate to define a top opening;
• an elastomeric sheet covering a portion of the top opening, the elastomeric sheet comprising a workpiece opening having a size and shape in accordance with the workpiece;
• a plurality of pins arranged along an interior surface of the bottom wall, the plurality of pins comprising at least three fixed length pins and a plurality of adjustable length pins;
• and
• a lateral clamping mechanism that applies a lateral force to the plurality of pins during the machining operation, the lateral force configured to lock the plurality of pins at a height that corresponds to a bottom surface of the workpiece.
