ABSTRACT:
A method and apparatus are provided for total profile machining of a part, such as from a block of thermoplastic polymer. A first side of the part is machined together with an encircling recess. A registration/potting fixture is placed into the encircling recess. The registration/potting fixture is used to evacuate air from the machined side of the part and to pressure pack degassed fluid potting compound against the machined side of the part. The registration/potting fixture is cooled such as with a coolant to solidify the potting material. Then the registration/potting fixture is used to fixture the block in a new orientation for CNC machining another side of the part. Upon removal of the potting material from the part, the total profile machined part is freed for shipment to the customer.
